In this study, the effect of runoff from alluvial soil on fish diversity in river Oko-Mayon along Sagamu express road between February to August, 2017 was assessed. Fish samples from fishermen using assorted gears were identified to the species level. Soil sample was collected using soil auger from the bank of the river to determine the alluvial level. Water quality parameters were also determined. The results showed that 311 fish species sampled had 13 fin fish species from 12 families. Mochokidae family had the highest composition(21.21%) while the most abundant fish species in the river was Synodontis violacea. The values should be for Physical and Chemical parameter of soil assessed included temperature (27.84±0.90-27.98±0.084)?C, %, sand (75.28±3.85-78.48±9.65), % silt (7.68±1.67- 9.60±3.17), % clay (11.92±2.54-17.04±2.83), pH (13.30±0.09-13.37±0.10), Conductivity (84.20±19.77-122.00±25.17), Total dissolved solid (42.20±9.81-60.60±12.34) mg/L, organic carbon (0.61±0.60-0.70±0.45), nitrates (0.11±0.01-0.14±0.02) mg/l, Phosphate (34.16±3.06-42.56±1.50) mg/l, with significant difference (p<0.05) except in percentage of sand and silt.

Published: February 2021

Consumption of processed meat products has greatly increased due to availability and accessibility of ready to eat meat products. Despite increased patronage of ready to eat meat products, food safety implication of processed ready-to-eat-meat products is of global concern. Against this background, this study was aimed at assessing the quality and safety of processed ready to eat meat products sold in Ibadan. Samples of asun, suya and kundi were randomly collected from four selected markets in Ibadan metropolis and subjected to chemical analyses. The total cholesterol content in suya (1538.00 mg/100mg) was significantly higher (P<0.05) than in asun (1277.60 mg/100mg) and kundi (1277.60 mg/100mg). Kundi had significantly (P<0.005) higher crude protein (70.66 %) and ether extract (23.42 %) than asun with 20.17 % and 10.85 % ether extract, respectively. Lipid peroxidation of suya (6.18 mg/MDA/kg) at day 28 was significantly higher (P<0.05) than kundi (4.50 mg/MDA/kg) and asun (4.19 mg/MDA/kg). The total polycyclic aromatic hydrocarbon (TPAH) was 5.31μg/kg in suya, 2.02μg/kg in asun and 1.55μg/kg in kundi. The total heterocyclic aromatic amine (THAA) was 51.66 ng/g in suya, 28.12 ng/g in asun and 23.70 ng/g in kundi. The total heterotrophic bacteria count in suya (28.17 ×10-3cfu/g) was higher than in kundi (11.19 ×10-3cfu/g) and asun (3.99×10-3cfu/g). Therefore, safe keeping and quality of suya in Ibadan metropolis was low based on the above parameters measured.

The study was aimed at assessing the effects of two varieties of cashew (Anacardium occidentale) apple pulp as feedstuff for ruminants. Samples of the yellow and red varieties of cashew apple pulp were collected, processed and analysed for mineral, crude fiber fraction and pH. Results showed that sodium value in red variety was significantly higher (P<0.05) than that of the yellow variety. Potassium value in red variety was significantly higher (P<0.01) than that of the yellow variety. Values for calcium, magnesium, and phosphorus in the yellow variety were significantly higher (P<0.01) than those of the red variety. Values for cellulose, hemicelluloses and neutral detergent fibre in the red variety were significantly higher (P<0.01) than those of the yellow variety. Acid Detergent Lignin value for the yellow variety was significantly higher (P<0.01) than that of the red variety. Values for acid detergent fibre, crude protein, carbohydrate and pH were not significantly affected (P>0.05). Yellow cashew apple pulp from the results of this study is richer in minerals when compared to the red variety. Results from the crude fibre fraction suggest that the yellow cashew apple pulp variety may have a better digestibility when compared to the red variety. Although the values of the various parameters from the 2 varieties show that they are fit to be used as feeding stuff for ruminants, the yellow variety appears to be better on the general basis.

This study was carried out to evaluate the haematological and blood biochemical parameters of broiler chickens fed graded levels of Roselle Seed Cake (RSC) diet as replacement for groundnut cake (GNC). Proximate composition of the test diet and experimental diets were conducted to determine their nutrient contents. Four diets were formulated for the broiler chickens. The Diet 1 served as the control diet while diets 2, 3 and 4 contained 8%, 16% and 24% with Roselle seed cake (RSC) diets respectively as replacement for groundnut cake (GNC). A total of 120, one day-old Ross broiler chicks were randomly allotted to four dietary treatments with four replicates and each treatment consisted of 30 birds in a Completely Randomized Design (CRD). Feed and water were provided for the birds ad libitum. The blood parameters measured are haemoglobin, packed cell volume, red blood cell, white blood cell, heteropils, lymphocytes, monocytes, eosinophils, basophils and band cell. The results from the parameters measured for blood quality showed no significant (P?0.05) differences for haemoglobin level, packed cell volume (PCV), white blood cell (WBC), across the treatments. But the red blood cell (RBC), heterophils and lymphocytes had a significant difference across the dietary treatments and this implies that Roselle seed cake (RSC) inclusions in the diets of the birds had a positive effect on the oxygen carrying capacity, immunity level and antibodies producing capacity of the birds. The blood biochemical parameters measured are total protein, albumin, cholesterol, creatinine, triglycerides, HDL and LDL. The parameters measured showed no significant (P?0.05) differences in total protein (TP), creatinine, high density level (HDL) and low density level (LDL) across dietary treatment while albumin and cholesterol had significant differences (p>0.05) across the dietary treatments. RSC can replace GNC at 16% dietary inclusion levels.

A study was conducted to evaluate the reproductive performance/reproductive organ weight of Nigerian indigenous chicken (cock) fed diet with graded levels of turmeric rhizome powder (TRP). The objectives of the study were to determine the effect of TRP on the characteristics (relative organ weight), and to evaluate the effect of TRP supplemented diet on the reproductive organ weight of Nigerian Indigenous cocks. One hundred and twenty adult local breeding cocks divided into four groups with 30 birds in each group were used for the study. Each group was further replicated into three replicates of 10 birds per replicate. The birds in the experimental groups designated as T1 , T2 , T3 , and T4 were fed with TRP supplemented diet at various inclusions, 0.0%, 0.25%, 0.50 %, and 0.75% respectively for eight weeks. The following parameters were measured, full reproductive organ (g), right vas deferens (g), paired vas deferens (g), right epididymis (g), left epididymis (g), paired epididymis (g), right testis (g), left testis (g) and paired testis. The result showed a gradual (p < 0.05) decline in reproductive morphometric weight and were significantly (p < 0.05) improved in the TRP supplemented group better than the control group. In conclusion, Turmeric powder supplemented diet at 0.25, and 0.5 % inclusions performed better in the reproductive morphometric of Nigerian indigenous cocks, although care should be exercised in prolonged supplementation above 0.5 % inclusion to prevent its deleterious effect on the organ weight. The reproductive organ weight of Nigerian indigenous cocks fed with Turmeric powder supplemented diet as observed in this study compared favorably and even better than the control T1. This is an indication that Turmeric powder has a significant propensity to enhance the reproductive performance of our indigenous cock semen since semen quality is determined to a large extent by the size of the reproductive organ. Although, the Turmeric powder has no significant deleterious effect on the major reproductive organs which make it very safe for inclusion in the diet of our local indigenous cocks. Also from the study, to a better performance, good morphometric quality and size of the Nigerian indigenous cocks and with no negative effect on the reproductive performance of Nigerian Indigenous Cocks, 0.5% inclusion level is highly recommended.

This study was conducted to assess the growth performance, carcass traits and economics of production of broiler fed soya bean replaced with gliricidia sepium leaf meal diet. One hundred, 4 weeks old broiler chickens were randomly distributed to five treatments of two replicates with t10 birds per replicate. The birds were fed trial diets containing 0, 10, 20, 30 and 40% levels of soya bean replaced with G. sepium leaf meal for five weeks. Parameters measured included weight gain, weight of feed consumed, feed gain ratio, price per kg of feed, price per kg of broiler and weights of carcass parts among others. Data were analyzed using Analysis of Variance. Results showed that weight gain were not significantly influenced (P>0.05) by the dietary treatments. Feeding trial exerted effects on feed intake however, feed gain ratio and feed efficiency were not significantly different (P>0.05). No significant difference (P>0.05) was observed in thigh, wing and breast muscle weights of the birds fed G. sepium meal substituted diet however, liver weight was significantly affected by the diet. Price/kg of feed reduced with increased G. sepium in the diets but the cost per/kg animal produced was not significantly affected (P>0.05). It could therefore be suggested that soya bean meal could be replaced with G. sepium leaf meal up to 40% level without adverse effect on performance and weights of major primal parts of the bird. This will also reduce the cost of feed and competition for soya beans between man and livestock industry.

Published: February 2021

A 63-day study was conducted to evaluate the dietary effect of Pleurotus pulmonaris treated cocoa bean shell meal diets on fibre fraction utilization of West African Dwarf (WAD) goats (aged 9 -12 months) with an average live weight of 6.31±0.3 kg. Six diets were formulated such that wheat offal was replaced with ensiled Pleurotus pulmonaris treated cocoa bean shell meal at ratio 0 (A), 20% (B), 40% (C), 60% (D), 80% (E), 100% (F) in complete diets. The experimental diets were fed to 18 WAD goats in three replicates per treatment using completely randomized design. The determined parameters included; chemical composition of the diets, dry matter and fibre fractions intake, weight gains and feed to gain ratio. The dry matter of raw cocoa bean shells was 88.53% and dry matter of Pleurotus pulmonaris treated cocoa bean shells was 87.38%. The crude protein contents of raw bean shells and Pleurotus pulmonaris treated cocoa bean shells were 11.98 and 26.63% respectively. The dry matter of the diets ranged from 86.83 to 90.70%, diet B had the highest value while crude protein ranged between 19.73 (diet A) and 28.88% (diet F) and increased with increased inclusion of Pleurotus pulmonaris treated cocoa bean shell meal in the diets. The nutrients intake was significantly (P<0.05) influenced by the treatment except dry matter and cellulose. The crude fibre and fibre fractions were efficiently digested. Nitrogen balance, apparent digestibility and weight gain were significantly (P<0.05) influenced by the treatment. The goats fed diet A converted their feed to flesh better than other goats. However, goats fed diet F performed best compared to other goats fed diets B, C, D and E that contained Pleurotus pulmonaris treated cocoa bean shell meal. It can be concluded that Pleurotus pulmonaris treated cocoa bean shell meal incorporated in goat's diet could supply energy and protein to sustain the growth without adverse effect.

Published: February 2021

The effects of feeding different levels of a concentrate supplement to growing rams fed ammoniated ensiled threshed sorghum top (AETST) as basal diet on voluntary intake and body weight changes were evaluated. The experiment consisted of four treatments: 0, 300, 450 and 550 g/d in a completely randomized design using 16 growing Yankasa rams. Data collected include feed intake, growth performance and economy of production. Except for AETST intake, and dry matter (DM) intake (% BW) and feed/gain ratio (F/G) which were higher (P<0.05) for the non-supplemented control, total DM, crude protein (CP) and organic matter (OM) intakes and average daily gain (ADG) were greater (P<0.05) for the supplemented diets. Among the supplemented groups, intakes of DM, OM and CP were higher (P<0.05) and F/G lower (P<0.05) for 450 and 550 g/d concentrate levels compared to 350 g/d level. Concentrate intake and ADG followed this rank order: 350 g/d < 450 g/d < 550 g/d P<0.05). Total cost of feed consumed/ram, weight gain (mutton) and monetary value (Naira) of mutton were higher (p<0.05) for T4 than for T1, T2 and T3 diets. Net benefit was higher (p<0.05) for T1, differential and relative benefits were superior (p<0.05) for T2. The study suggests that feeding ruminant animals with AETST supplemented with lower level of concentrate can improve voluntary intake, body weight and economic benefits to farmers. However, diet with 350 g (T2) concentrate supplementation had better economic benefit than other dietary treatments.

Published: February 2021

Testosterone has been reported to have anabolic influence on various organs of animals. Thus, an experiment was carried out to investigate the influence of crude testosterone in bovine testicular fluid (BTF) on the growth performance of broiler chickens. One hundred and twenty-five broiler chicks (Abore Acre) were used. They were raised for one week and randomly allotted into five treatments consisted of five replicates (five chicks per replicate) under the intensive management system. Four different levels; 25mL, 50mL, 75mL, and 100mL of bovine testicular fluid per litre of water were administered to the birds, while the control birds were offered ordinary water. Feeds (broiler starter and finisher diets) were provided ad libitum on daily basis at weeks 2-4 and 5-8, respectively and clean water was given at free choice throughout the period of the study. Average daily feed intake (ADFI), average daily water intake (ADWI), average daily weight gain (ADWG) per bird, and the feed conversion ratio (FCR) of the birds were determined. At week seven blood was sampled to assay for level of the luteinizing hormone (LH), follicle stimulating hormone (FSH), and testosterone. The results indicated that ALW and the ADWG of the T5 birds (1850.00g/bird and 43.79g/bird, respectively) were significantly (p<0.05) higher than birds in T1, T2, T3, and T4, while the ADFI of T1, T3 and T4 birds (90.33g/bird, 94.09g/bird, 90.39g/bird respectively) were significantly (P < 0.05) higher than T2 (84.60g/bird) and T5 (84.60g/bird). ADWI of the T5 and T4 birds (101.01mL/bird, and 98.68mL/bird, respectively) were significantly (P < 0.05) higher than TI (82.13mL/bird), T2 (86.50mL/bird) and T3 (93.01mL/bird) birds. Birds administered 100mL of BTF/litre (T5) had the best percentage carcass yield and feed conversion ratio of 76.60% and 2.11 respectively, among the treatments T1, T2, T3, and T4 birds. The result of the enzyme-linked immunosorbent assay of the serum concentration of the sex hormones showed that the expression of the serum testosterone increased as the inclusion levels of the Bovine testicular fluid increased with birds on T5 having significantly (P < 0.05) higher values (3.64 nmol/L) than those on the control (2.60 nmol/L). However, testosterone levels in T2 (3.18 nmol/L), T3 (3.24 nmol/L) and T4 (3.40 nmol/L) was not significantly different from T5. This study suggests that 100ml of bovine testicular fluid per liter of the drinking water can be used as a growth promoter for broiler chickens.

Published: February 2021

This study evaluated the effect of aqueous extracts from cocoyam leaf on the growth performance of broiler chickens fed full-fat Soya bean. The study was carried out with seventy-two (72) day old broiler chickens in a completely randomized design. The seventytwo (72) broiler chicks were randomly assigned into four groups (T1, T2, T3 and T4), each treatment had (3) birds per replicate. The T1 which was the control, contained 0g of aqueous extract of cocoyam leaves while the birds in T2, T3 and T4 were offered aqueous extract of cocoyam leaves at 100g, 150g and 200g per 6 liters of water, respectively. The test ingredients were analyzed for nutritional and phytochemical composition. Data was collected from the broiler chickens' daily feed intake, feed conversion ratio, specific growth rate, body weight gain and daily weight gain. There were no significant differences (P>0.05) on the feed intake, daily weight gain, feed efficiency, feed conversion ratio, initial and final body weights of the broiler birds. However, total water and mean daily water intake differed significantly (P>0.05). The extract administered groups (T2, T3 and T4) had lower water intake as the quality of cocoyam leaves increased. The significant variations in the water intake as the quantity of cocoyam increased may be attributed to anti-nutrient factors (tannins) found in the leaves. The cocoyam leaves are rich in nutrients when assessed by the proximate and mineral composition. It can serve as a feedstuff for livestock. Cocoyam leaves extracts should be used with caution due to the anti-nutritional factors present in it. It is therefore safe to recommend 100-150g of cocoyam leaves/ 6litres of water for broiler chickens without any negative impact on growth rate of the broiler chickens.

An experiment was conducted to investigate the replacement value of Acha (Digitaria exilis Staph) for maize in broilers diets. Five diets were formulated in which unprocessed Acha replaced maize at 0, 25, 50, 75, and 100% levels for the starter phase. Two hundred and twenty-five unsexed Marshall Broiler chicks were weighed and randomly allotted to the five dietary treatments with three replicates per diet in a complete randomized design (CRD). The highest (P<0.05) daily feed intake (71.,90g) and (P<0.05) daily weight gain (24.60g) were obtained in the birds fed diet 5 while the best feed conversion ratio was found in diet 2 as 2.55. Hematological evaluation was done at the end of the experiment and, the dietary treatments had no significant (P>0.5) effect on RBC (x102L, WBC (x109K Hbc (g/dl) MCH (pg) and MCHC (g/dl) and had significant (P<0.05) effect on PCV%, Lymphocytes (P<0.001) and Neutrophiles (%). Unprocessed Acha (Digitaria exilis Staph) could completely (100%) replace maize as energy source in the diets of broiler chicks at starter phase.

Published: February 2021

Considering the inherent attributes of processed African Yam bean meal (Sphenostylis stenocarpa), it's appropriate utilization for chicken diets may enhance performance of finisher broilers. The study was therefore carried out to determine the dietary substitution of soybean meal with processed African yam bean meal as protein source in the diets of finisher broilers. The Processed African yam bean meal was used to substitute soya bean meal at various levels to determine the best substitution that would give optimal performance in finisher broilers. The seeds of the African yam beans were soaked in water for 24 hours The soaked seeds were thereafter air dried for three days. The seeds were toasted for 35 minutes in a frying pan and milled using hammer mill. In the finisher feeding trial, the  substitutions were 20%, 40%, 60% and 80% processed African yam bean meal respectively. Each finisher diet was fed to a group of 30 broilers for 4 weeks using completely randomized design. Each treatment group was divided into 3 replicates of 10 broilers chicks each. The finisher broilerswere kept in pens in deep litter and given feed and water ad libitum. The parameters measured included initial body weight, final body weight, feed intake, body weight gain, feed conversion ratio, cost of production and carcass characteristics. The proximate composition of processed African yam bean meal showed that it contained 8.29% moisture, 91.71% Drymatter, 3.40% ash, 21.12% crude protein, 5% ether extract, 5.73% crude fiber and 56.4% nitrogen free extract. In the finisher feeding trial, the broiler group on 40% processed AYBM significantly (P<0.05) recorded higher body weight gain than the rest of the treatments possibly because of the proper substitution of soya bean meal with processed AYBM in their diets and it appeared that the finisher broilers could tolerate high levels of processed AYBM in their diets. The group on diet 2 (20% AYBM) and control diet recorded similar body weight gain (P>0.05) which were significantly (P<0.05) superior to the groups on diets 4 (60% AYBM) and 5(80% AYBM). The internal organs expressed as percent of the live weight were not affected by the treatments. Cost of production (cost/kg feed x feed conversion ratio) was lowest for diet 2 (N450.64) as against N480 for the control diet. The finisher broiler on diet 3 (40% AYBM) recorded the highest dressing out percentage of 78.78. The results of the trial have shown that processed African yam bean meal can be used to substitute soya bean mealin the diet up to 40% for optimum performance of the finisher broilers without affecting the body weight gain, feed intake, feed conversion ratio and carcass  characteristics as indicated in this study.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

This study focused on polymorphisms of haemoglobin in some indigenous ruminants. Blood samples were collected from a total of 2400 ruminants (600 cattle, 900 goats and 900 sheep) and analyzed. Body Weight (BW) and Nine linear body measurements viz: Height at withers (HW), Body length (BL), Heart girth (HG), Face length (FL), Neck length (NL), Neck width (NW), Rump width (RW), Ear length (EL), Tail length (TL) and shoulder width (SW) were measured on each animal prior to blood sample collection. The results revealed that animals with heterozygotes genotype Hb AB had higher values for body weight (313.42 kg), body length (158.23 cm), shoulder width (28.21 cm) and heart girth (150.39 cm) in cattle. In goats, individuals with Hb BB and Hb AB had similar heart girth (69.33 and 66.16 cm), body weight (21.08 and 20.92 kg), and shoulder width (10.43 and 10.23 cm), though they were better than those with Hb AA genotype. In conclusion, while Hb AA is an adaptation genotype in sheep, Hb AB is the genotype of choice for both adaptation and meat traits in cattle and goats.

Globally, hunger and poverty are major challenges with number of household malnourished increasing daily. Conscious integration of the home gardens strategy into peri-urban and urban development can help to achieve food security. In this regard, a total of 412 questionnaires were administered to home garden owners around the National Horticultural Research Institute (NIHORT) in Ibadan (Southwest Nigeria), Mbato (Southeast Nigeria), Bagauda (Northwest Nigeria) and Dadinkowa (Northeast Nigeria). In all, 366 (88.8%) questionnaires were found suitable for analysis. The data collected was analyzed using descriptive statistical analytical tools. Majority of people involved in the practice of home gardening were male (78%) and young <50 years (53%), implying that they were capable of handling more tedious activities than the female and the elderly respectively. Land and house ownership were found to be the most important factor in home gardening. Goat (77.1%), sheep (58.7%) and local fowl (49.7%) were the dominant livestock in the areas investigated.Most of the livestock were fed with household waste and crop residues which ought to have caused great problem through microbial build up, while the animal wastes were usually incorporated into the soil to serve as soil amendments. Some of the livestock owners were also mindful of zoonosis.

This study was carried out to determine rumen dry matter degradability of Brachiaria ruziziensis (Congo grass) by cannulated Yankasa rams fed different supplements (maize offal, wheat offal, groundnut hay). The research was carried out at Polycon Research farm, Federal Polytechnic Bauchi. Four (4) cannulated Yankasa rams were used for the study, each animal was replicated three times. In-sacco method involving small nylon bags containing experimental diets were inserted into the rumen of the cannulated rams at 0 hour, with inspection at 6, 12, 18 and 24 hours. Three (3) nylon bags marked with different colours containing different treatment diets were inserted into the cannula of the rumen to test for degradability, the small nylon bags were removed at different hours (6, 12, 18 and 24 hours, respectively) to test their degradability. The supplementary treatment diets were wheat offal (WO), Maize Offal (MO) and Groundnut Hay (GH) while Brachiaria ruziziensis was fed as basal diet. The rumen degradability showed significant difference (P<0.05) across the treatments at different hours. Results from this study showed that MO had the highest value (P<0.05) at 0 (27.20%), 6 (36.75%), 12 (38.62%) and 18 (46.15%) hours. However, WO had the highest value (64.72%) at 24 hours, but the value obtained was similar with 61.32% obtained for rams fed maize offal supplement. It was concluded from the result of this study that treatment T2 (Brachiaria ruziziensis + Maize offal) had the best rumen degradability. Itis therefore, recommended that maize offal should be supplemented with Brachiaria ruziziensis hay at 370g/day for better rumen degradabilit y in ruminant animals.

A 21-d investigation was conducted to ascertain the effect of 50% whole millet grain replacement for milled millet on growth performance, gastrointestinal conditions and development in broiler chickens. Eighty-four one-day-old unsexed broiler chicks were randomly allotted to two treatment groups with 7 replicates of 6 chicks per replicate. Two diets; whole millet diet (WM), consisting of 50% of the millet provided as whole grain, and the ground millet diet (GM), as the control, were formulated and fed ad-libitum throughout the study period. Performance data: feed intake, daily live weight gain and feed conversion ratio were recorded weekly, i.e. at 7, 14 and 21d, while gastrointestinal assessment: jejunal, digesta pH, relative weights of the proventriculus, gizzard, pancreas and liver, and jejunal and ileal morphometry were conducted on 21d. Similarities (p > 0.05) were observed in the growth performance, digesta pH and relative weight and length of duodenum, jejunum, ileum and caeca for chickens in both treatments. A 25.7% increase in gizzard weight was observed in chickens on WM, as well as significant (p < 0.05) increases in jejunal and ileal height and jejunal villus width were recorded on the chickens. A significant reduction in flock uniformity was observed in chickens fed the whole millet diet at 14d. It could therefore be concluded that 50% whole millet grain replacement for milled millet resulted in similar growth performance and improved gastrointestinal function and activity in 21-d post hatch chickens.

Insufficient quantity and quality of feed for ruminants during the dry season is a major limiting factor for effective production and management. Smallholder farmers generate large crop residues in the wet season, which are rich in nutrients in which ruminants can feed on in the dry season by proper ensiling. Cassava Leaves (CL) and Maize Stover (MS) residues were thus ensiled to evaluate their nutritional qualities as feed for ruminants. Fresh cassava leaves and maize stover were collected, chopped and wilted. Silages were prepared as: T1 (100%CL), T2 (100%MS), T3 (50%CL+50%MS), T4 (25%CL+ 75%MS) and T5 (75%CL+25%MS). Ensiling lasted for 21 days after which they were opened to determine the quality using physical assessment of colour, smell, texture, pH and temperature. Chemical composition of the silages comprising Crude Protein-CP, Crude Fibre-CF, Ether Extract-EE, ash content, Acid Detergent Fibre-ADF, Neutral Detergent Fibre-NDF and Acid Detergent Lignin-ADL were assessed. Nutritive values of the diets were evaluated using in vitro fermentation technique to determine Total Gas Production (TGP), methane, Metabolizable Energy (ME), Short Chain Fatty Acids (SCFA) and Organic Matter Digestibility (OMD). Coefficient of Preference (COP) was determined using a cafeteria feeding technique. Olive-green colour, alcoholic smell and firm texture were observed in the silages. The pH ranged from 4.13 to 4.73 while higher pH was observed in 100%CL. The temperature was between 31°C and 32ºC. The values obtained for the DM ranged from 64.37 to 67.9%. The CP values varied between 8.64 and 19.68%. The lowest CP of 8.64% was observed in T2 (100%MS) while 19.68% was obtained in T1 (100%CL). The ash content ranged from 8.65 to 13.00% and the CF value varied from 33.70 to 40.39%. It was observed that 100%MS had significantly (P<0.05) higher CF (40.39%) compared to other treatments. The EE values varied between 4.45 and 5.22%. The EE value in 100%CL (5.22%) was significantly (P<0.05) higher compared to other silage treatments. The NDF, ADF and ADL values varied from 62.70-69.80%, 43.95-47.90% and 22.95-25.80%, respectively and significant differences were observed. The total gas volume ranged from 8.33 to 13.8mL, methane 5.3 to 7.6, OMD (32.72-42.5%), ME (4.06-5.28kCal) and SCFA (0.15-0.27). The CoPof the silages was ≥to the unity of one with the exception of T2. It can be concluded that, combinations of 50% cassava leaves and 50% maize stover could be used as feed for ruminants.

An experiment was conducted to evaluate the comparative effect of feeding sundried sweet potato and its whole meal to weaner rabbits. The proximate analysis conducted revealed that sundried sweet potato meal and whole sundried sweet potato meal samples were rather low in protein contents as compared to maize. Twenty seven Weaner rabbits averaging 0.35kg were randomly allotted to 3 treatment groups in a completely randomized design. Each treatment group was replicated 3 times. Sundried Sweet potato meal and its whole meal replaced maize at 20% inclusion level. Treatments 1, 2, and 3 contained the control, sundried sweet potato meal (SSPM) and whole sundried sweet potato meal (WSSPM) respectively at 20% levels of inclusion. The weaner rabbits were fed ad-libitum throughout the experimental period. Significant differences (p<0.05) were observed for growth performance of the rabbits in average daily weight gain, average daily feed intake and feed conversion ratio in the weaner rabbits using sundried sweet potato and its whole meal. The values of mean daily weight gain ranged from 16.33g in treatment 2 (SSPM) to 18.47g in treatment 1 (control). Treatment 3 (WSSPM) gave a higher value that is comparable (p>0.05) to that of the control diet but better (p<0.05) than that of treatment 3 (SSPM). The values of average daily feed intake also ranged from 43g in treatment 2 (SSPM) to 50g in treatment 1 (control). WSSPM was consumed more than (p<0.05) than the SSPM which however influenced the cost of total feed consumed. Moreover, the values of feed conversion ratio (FCR) ranged from 2.54 in treatment 3 (WSSPM) to 2.70 in treatment 1 (control). Significant differences (p<0.05) were also observed in bio-economics of production of weaner rabbits using the test diets. The cost per kg feed, cost of total feed consumed per rabbit, cost per kg weight gain and revenue of the rabbits fed the test diets were significantly lower than the control diet however, the cost per kg weight gain was lower (p<0.05) for treatment 3 (WSSPM). For gross margin, WSSPM value was significantly higher (p<0.05) than SSPM value and the control diet. It was concluded that whole sundried sweet potato meal can be a good feed ingredient in rabbit diet.

Effect of toasted jackfruit (Artocarpus heterophyllus) seed meal (TJSM) on performance of 120 2 weeks old broiler chickens was investigated. The birds were divided into four dietary treatments having 3 replicates and 10 birds per replicate in a completely randomized design. Diet one (T) was soybean based while toasted JFSM meal was added to diets 2 (T), 3 (T) 1 2 3 and 4 (T) at 5, 10 and 15% levels of inclusion, respectively. Growth performance was 4 generally depressed with increased inclusion of toasted JFSM in the diets. Feed conversion ratio of birds fed T and T were the same and significantly better (P>0.05) than those of the 1 2 remaining treatment groups. Birds fed T had significantly higher values of live weight, 1 dressed weight and dressing percentage followed by birds fed T. The prime cut parts were 2 similar in all the treatment groups. Organ proportions showed no significant differences across the treatment groups except the spleen. Cost per kg feed decreased with increased inclusion of TJSM. The cost of feed consumed was higher (P>0.05) in T (531.29) but 1 decreased with increased inclusion of TJSM. The cost per kg weight gain, cost of production and revenue were similar across the treatment groups with birds fed T significantly higher 1 (P>0.05) than the remaining treatment groups. The gross margin obtained for birds fed T 1 and T are comparable and higher than other treatment groups. From the foregoing TJFSM is 2 a potential feed resource and could be included in the diet of broiler chickens up to 5% inclusion level.

Carcass traits and relative organ weights of growing rabbits fed graded levels of processed (ash treated and rumen liquor fermented) kola nut (Cola nitida) pod husks (PKPH) were investigated. One hundred and twenty (120) weaner rabbits of mixed breeds (New-Zealand white × Chinchilla) of equal sexes and average body weight 525.46g were randomly allotted to four (4) dietary treatments at 0 (0.00 % PKPH), 10 (10 % PKPH), 20 (20 % PKPH), and 30 % (30 % PKPH) inclusion levels and designated as diets 1, 2, 3, and 4, respectively. Each treatment group was replicated ten (10) times with three (3) rabbits per replicate and was fed ad-libitum for 56 days. The highest slaughter weight (1813.80 g/r), dressing weight (1068.70 g/r) and dressing percentage (58.54 %) recorded in rabbits fed diet 3 (20% PKPH) were similar to those fed the control diet (0 % PKPH) and diet 2 (10% PKPH) but was significantly (P<0.05) higher than those fed diet 4 (30 % PKPH). The lungs, liver, kidney, heart, and spleen of the rabbits fed dietary treatments were not significantly influenced. It was concluded that processed kolanut pod husk had no deleterious effect on carcass and relative organs weight of weaner rabbits.

A total of 324 local pullet chicks (1- 8 weeks) were used for the research project to evaluate the feeding value of raw and boiled pigeon pea seed meal (PSM) on their growth performance. Nine iso-caloric and isonitrogenous diets were formulated, with raw and boiled pigeon pea seed meal at inclusion levels of 0%, 15%, 20%, 25% and 30%, respectively. There were 36 chicks per treatment replicated into 3 at 12 chicks per replicate. There were significant interactions between form and PSM levels on the final live weight, daily feed intake and daily protein intake. Final live weight of pullets fed both raw and boiled PSM followed the same trend, pullets fed control (0%) and 15% raw PSM 128.10 and 132.33g respectively performed better than the rest of the treatment levels but statistically similar at all levels. Daily feed intake and daily protein intake showed significant interaction among the treatments. Pullets fed control (8.95g) and raw diets (8.79g) consumed more feed than pullets fed boiled PSM II (105.05g), III (117.77g) IV (91.27g) and V (112.80g) diets. Daily weight gain, feed conversion ratio and protein efficiency ratio had no significant (P>0.05) interaction between form and treatment groups for the pullets. 30% PSM raw or boiled can be fed to local pullet chicks without any deleterious effect on the growth performance.

A feeding trial was conducted to evaluate the growth performance and nutrient of broiler chickens fed varied levels of steam-treated Cattle Rumen Epithelia Scrapings (CRESM) in replacement for fish meal at 0, 25, 50, 75, and 100% level. Two hundred and four (240), one-day old Abor Acre strain of broiler chickens used for the study were randomly divided into 5 treatments of four (4) replicates each. There were 12 birds per replicate to a total of 48 birds per treatment in a completely randomized design. Data were collected on the feed intake, weight gain, feed to gain ratio, feed cost per kilogram weight gain at the starter and finisher phases while digestibility trial was conducted at the finisher phase. The results indicated that feed intake (44.15, 48.20, 48.87, 47.18 and 49.30g) and weight gain (20.73, 24.13, 24.63, 23.69 and 23.34g) for 0, 25, 50, 75 and 100% CRESM, respectively were higher (P<0.05) and feed: gain ratio lower in birds that received diets containing CRESM at starter phase. Feed cost and feed cost per kg weight gain decreased with increased level of CRESM at this phase. At the finisher phase, feed cost per kilogram weight gain (₦260:01) of treatment five (100% inclusion of CRESM) was the lowest (p<0.05) compared with other inclusion while the control was the highest. It was concluded that 100% fishmeal could be replaced with steam-treated CRESM in broiler diets, thus ultimately reducing the production cost and increasing the profit accruable to farmers.

Molecular markers-based selection is a novel tool for unbundling complexities associated with the selection of animals for breeding improvement programmes because these markers could contribute to full exploitation of animal potential prior to enrollment for improvement programmes. This study examined in-silico polymerase chain reaction amplification of some selected Male Specific region Y (MSY) genes in genome assemblies including Bos_taurus_UMD_3.1.1/bosTau8 and ARS-UCD1.2/bosTau9;BaylorBtau_4.6.1/bosTau7, Bos_taurus_UMD_3.1/bosTau6, and Baylor4.0/bosTau4. The results of the amplification showed that 12 out of the selected 30 genes were expressed at an average primer melting temperature of 61.78 oC; while salt and annealing oligo concentrations were 50 mM and 50 nM per reaction, respectively. Out of expressed genes; 6, 5 and 1 genes were expressed in genome assemblies Bos_taurus_UMD_3.1.1/bosTau8, ARS-UCD1.2/bosTau9, and BaylorBtau_4.6. 1/bosTau7, respectively. The study concluded that the expressed genes are potential markers for selection of fertile bulls and the primers used are suitable for in-vivo annotation of the genes in the prospective bull selection process for breeding programmes.
