Authors: Martín Cristina Muñoz San , Tapia María Elena Martínez , Aguirre Luz Helena Sanin 
Published: March 2021

La vitamina D ha llamado últimamente la atención del ambiente científico al ser descritos sus efectos de inmunomodulación, desintoxicación xenobiótica, reducción de estrés oxidativo, defensa antimicrobiana, acción antiinflamatoria, además de su implicación en la salud ósea (Angel Gil, 2018) (Giancarlo Isaia, 2020). La caries es altamente prevalente y es un problema de salud pública que se ha asociado con diferentes predictores, como la dieta rica en carbohidratos. Sin embargo, un aspecto no documentado en México y que ha cobrado relevancia con respecto a la caries es la relación con la vitamina D. Con el objetivo de buscar la asociación entre las concentraciones de vitamina D y la caries se realizó este estudio de casos y controles, donde se seleccionaron 15 niños con caries y 15 sin caries, de la consulta del Hospital Infantil y de una clínica privada. A todos los niños se les determinó la vitamina D a través de la medición del nivel sérico de la 25(OH)D3. Se encontró que en el grupo de niños con caries la media de vitamina D fue 33.9 ± 7.5 ng/mL versus 34.4 ± 6.2 ng/mL en el grupo sin caries donde la proporción fue mayor en 1.4%. Si bien este es un estudio piloto vemos que la asociación entre la proporción de nivel de suficiencia de vitamina D tiende a la significancia. Encontramos elementos para decir que vale la pena hacer un estudio con un número mayor de niños para seguir ampliando esta línea de investigación.

Published: March 2021

The introduction of new and changing technologies has led to changes in all areas of society, and the world of work is no exception. This had created a need for an analysis and reformulation of habits and actions related to workplace health and safety. “Technostress” has emerged as one of the risks associated with the increasing use of information and communication technologies. The aim of this work is to analyze the effectiveness of positive psychosocial interventions aimed at technostress management. To do this, the two concepts are analyzed via a case study. The study begins with an assessment of technostress among the management staff of a service company. Based on the results of this initial assessment, a range of ongoing Positive Psychology interventions were designed and implemented. It is concluded that Positive Organizational Psychology can be an effective tool for technostress management. The main constraints of this work would be associated with the size of the sample, which does not allow the generalization of the results. Nonetheless, it opens a door to a new research paradigm to delve deeper into the issue of technostress management from the field of Positive Psychology, which a connection that to date has received scant theoretical attention.

Published: March 2021

Observations on the age at first breeding of West African Dwarf Sheep at the University of Ibadan. Nigeria showed that the optimal age and weight at 1st breeding of young ewes was not less than eleven months and at least 13kg respectively When mated earlier, the incidence of abortion in­creased and lambs tended to the smaller at birth. In ewes mated at older ages the lengthening of the generation internal was unacceptable. The relalionuship between weight (4 ) and age (X) from four to 56 weeks was estitnated as: Y (kg) = 3.12 + 9.62 x — 0.02 x 2 + 0.0002 x 3 for singles. or Y =2.59 + 0.46 x = 0.01 x2 + 0.0001 x 3 for Mins.
EFFECTS OF SPACING ON DRY MATTER YIELDS OF F1PENNISETUM HYBRIDS AND ELEPHANT GRASS (PENNISETUM PURPUREUM SCHUM)
Authors: Aken'ova M. E. , Chheda H. R. 
Published: March 2021

Crown splits of three bulrush millet (Pennisetum americanum) (L) K Schum) x elephant grass F1 hybrid genotypes and an improved local strain of elephant grass were set every 30, 45, 60 and 90 cm in rows 90 cm apart to ascertain the effects of spacing on forage dry matter (DM) yield. Plants were harvested by cutting 30 cm above ground level every 5 weeks during the late rainy season of the first year (4 harvests) and the rainy session of the second year (7 harvests). There were significant differences in DM yields between spacing treatments, as well as between genotypes. When averaged over genotypes, total DM yield in the two years of study at 90 x 30, 90 X 45, 90 x 60 and 90 x 90 cm were 31.16, 27.27, 25.75 and 23.13 t/ha, respectively. Genotype x spacing interaction for DM yield was not significant. Spacing, in general, had no appreciable effects on forage quality so that linear regression analysis revealed no relationship between spacing on one hand and DM content, percent leaf, crude protein (CP) content, and in vitro organic matter digestibility (IVOMD), on the other. The results indicated that close spacing can be utilized to increase DM yields of F1 Pennisetum hybrids and elephant grass without detriment to quality.

The effect of feeding different protein levels during the rearing and development of egg-type pullets as well as on eventual egg production was investigated in two experiments. In experiment I, the dietary crude protein (CP) regimens (and old to point of lay notations) in isocaloric diets for the periods 0-8 weeks and 9-20 weeks respectively for treatment 1: 20% and 16% (20:16), treatment 2: 16% and 16% (16:16), treatment 3: 12% and 12% (12:12), treatment 4: 16% and 12% (16:12), treatment 5:20% and 12% (20:12) and for treatment 6 theregimens comprised 20% for 0-8 weeks, 16% for9-16 weeks and 12% for 17-20 weeks (20:16:12) In experiment 2, treatments 1 to 5 for experiments 1 were repeated while three step-up dietary treatments 6, 7 and 8 were evaluated in addition. For the periods 0-8 weeks and 9-20 weeks respectively, the CP regimens for treatment 6 were 12% and 16% (12:20) and for traetment 7, 12% and 20% (12:20) and for treatment 8, 16% and 20% (16:20). From 20 weeks in each experiment, a common layer diet containing 16% CP and 2,449 Kcals metabolizable energy per kg was fed ad libitum to all treatments and all the subsequent egg production was monitored for a further 16 weeks . Both studies indicated that production was reported egg-type chickens fed diets with a drastic protein restriction (12%) in the starting period (0-8 weeks) had significantly reduced body weights at 20 weeks and delayed sexual maturity. However, when such birds were subsequently (9-20 weeks) offered diets with higher protein content significant compensatory effects on weight gain and feed conversion were indicated. The step-up CP règimens in experiment 2 performed.
SELENIUM AND VITAMIN E SUPPLEMENTATION OF HIGH N-ALKANE GROWN YEAST IN CHICK DIETS
Authors: Oguntona T. , Heale R. 
Published: March 2021

A total of four experiments have been conducted to evaluate performance of chicks given high (300/kg diet) n-alkane grown yeast diet supplemented with vitamin E and selenium. Four levels (0,10,20,30 mg) of vitamin E were examined in experiment 1 while five levels (0,12.5,15.0,17.5,20mg) were examined in experiment 2. Performance was also measured at four selenium supplementation levels (0, 50,100, 150 µg Se/kg diet) initially and finally at five other (0,100, 125, 150, 175 µg/kg diet) more detailed levels. Supplementation of a 300g/kg yeast diet with 15mg Vitamin E produced significantly (P < 0.05) higher body weight than unsupplemented high yeast diet. Higher levels produced no further growth response. At this level of vitamin E supplementation every level of selenium examined gave significant (P < 0.05) increase in weight but optimum growth response was obtained at 100µg Se/kg yeast diet. There were no significant treatment effects on feed intake at all levels of vitamin E and selenium examined. Nitrogen retention also showed no response at the highest levels (100 - 157µg) of selenium supplementation. The results show that supplementation with appropriate levels of vitamin E and selenium significantly reduced the depression in growth rate caused by high levels of inclusion of n-alkane grown yeast in chick diet.

Published: March 2021

A study was conducted to examine the influence of five environmental factors on birthweight (BWT) and litter birth weight (LBWT) and to obtain heritability estimates for both traits in Yankasa sheep. Records of 2490 lambs sired by 133 rams and 1225 lambs sired postnatally by 120 rams from 1983-1993 at Shika were analysed for BWT and LBWT, respectively. The Yankasa flock was semi-intensively l managed in an accelerated lambing programme. Least-squares means were 2.48±0.03 kg and 3.57±0.03 kg for BWT and LBWT, respectively. All five environmental LBWT in factors considered (parity, sex, type of birth, Yankasa sheep High season and year of birth) were highly significant (P<0.001) for both traits. Lambs from multiparous ewes had higher body weights than lambs from primiparous ewes. Likewise, rainy-season-born lambs were heavier than dry-season-born lambs. Ram lambs were consistently heavier than ewe lambs for both traits, their superiority also being reflected in higher LBWT for mixed sexes. Single born lambs. were, superior to single lambs for LBWT. Heritability estimates by paternal half sib analysis, after appropriately adjusting data for the fixed effects,were 0.410, 0.8 and 0.12±0.07 for BWT and LBWT, ; respectively. These results indicate that high genetic response is expected from selection for BWT, while low response is expected for LBWT. Adjustment for environmental effects is necessary to enhance the accuracy of selection for superior individuals in terms of gene expression for these traits.

The first of two experiments was conducted to substitute cassava starch for molasses at levels of between 0 and nutrient blocks are discussed. 100% in urea-molasses blocks in six treatments. In a second experiment, of Gliricidia sepium, Leucaena leucocephala Gmelina arborea and cement were included at 15% levels respectively as substitutes to cement as feed block binders. A fifth treatment combined cement and the various leaves as binders. Parameters monitored included block hardness, stability in water, colour, storability, nutrient quality and cost. Results showed that the blocks dried within 3 - 7 days and the weights of the blocks progressively decreased (P<0.01) within the drying period, Final block weights were 88 to 97.5% of initial weights. The crude protein contents of the 100% molasses blocks were lower while the fibre contents of the leaves - substituted blocks were higher (P>0.05) between 25 and 28% CP. The blocks were strong and did not dissolve in water for 3 to 5 days. Increasing levels of cassava starch substitution made the blocks harder, Block colours varied from dark brown to dirty white. Use of leaves as binders reduced the cost of the blocks by as much as 20%. Blocks stored better when the sides of the plastic mould were lined with cellophane paper. The cassava substituted blocks stored up ic 9 months without moulding. Gliricidia sepium leaves, however, served as a good binder just like the other two leaves types used. aThe implication of using cassava starch and browse leaves in urea-molasses multinutrient blocks are discussed.

Published: March 2021

Meat samples from West African dwarf buck Were stored at -10°C for 6 weeks with the aim studying the effect of frozen storage duration on organoleptic properties. Analysis of variance showed that the flavor of the meat was significantly better (P<0.05) at the commencement of storage than 2 weeks later. generally objectionable, Mean flavor rating at 4 weeks was higher (P<0.05) than that at 6 weeks but no higher than rating at 2 weeks (P>0.05). Changes in color and juiciness were not significant (P>0.01) throughout the storage period while those in texture and overall acceptability were non- significant (P>0.05). There were high, but negative and very highly significant correlation (r-0.83to -0.99; P<0.001) between the duration of storage and organoleptic properties, as well as duration accounting for 90% and 99% of the variabilities in flavor and acceptability respectively. Strong positive and very highly significant correlations (r=0.87 to 0.97;P<0.001) were observed between acceptability juiciness, texture and flavor ratings. The strong influence of flavor on acceptability supported the widespread but unpublished indications and reports of the desirability of the strong sex odour by buck meat consumers in southeastern Nigeria.

Authors: Faniyi G. F. 
Published: March 2021

Maize was replaced with Mango seed kernel meal MSKM at 50% levels (w/w) in broiler starter and finisher diets in an eight week feeding trial. 120 day-old broiler chicks were used for the experiment, 30 chicks were randomly assigned to each of the four treatments in a completely randomized design. There were differences (P <0.05) in the average feed intake, average body weight gain and feed conversion efficiency during both phases. Mortality was generally low. However, as MSKM content of the diets increased, performance of the broiler decreased at both phase. At the end of the starter phase, feed intake (g/bird) was 1363, 1239, 1275, 1075 for the diets that contained 0%, 50%, 75 and 100% MSKM respectively. At the finisher phase, consumption was higher in the maize – based diets (0%) and least in 100% MSKM – based diet. Body weight gain (g/bird) was 568, 422, 390, 510 and 310 at finishing in that order for the diets that contained MSKM 0%, 50%, 75% and 100%. Feed cost kg-1 and feed cost kg-1 live weight gain increased from 0% to 100% MSKM could be used as an energy source in broiler diets but it need further processing to fully realise this potential

Published: March 2021

Digestibility trials carried out in November and December, 1971 with twelve West African dwarf ram fed Cynodon nlemfuensis var. robustus; Cynodon nlemfuensis var. nlemfuensis: Pennisetum purpureum Schum; and Panieum maximum, Jacq, each at 4 weeks and 8 weeks of regrowth showed that the differences that may exist between methods and among treatments in organic matter digestibility were not statistically significant (P> 0.05). Similarly, analysis showed no significant differences among animals or between periods within each treatment except for Cynodon nlemfuensis var. nlemfuensis where differences between period were significant (P <0.01). There were high positive correlations between in vitro and in vivo organic matter digestibilities as well as between in vitro organic matter digestibility and Total Digestible Nutrients (TDN). It is suggested that in vitro organic matter digestibility can be used to predict the digestibility of these tropical grass species and, may be, other similar grass species.

Authors: Olaloku E. A. , Fagbohun A. F. 
Published: March 2021

Samples of four major brands of tinned evaporated milk purchased from the local markets in Ibadan and cartons of pasteurized fresh milk from the Iwo Road dairy were left sealed or unsealed after opening. The samples were then stored on the shelf, in a bowl of water or in a refrigerator (storage conditions commonly used in many Nigerian homes). At 0, 24, and 48 hours, the samples were assessed for percentage fat and protein as well as bacterial quality using the plate count and the dye reduction tests. The results showed that percentage milk fat remained unchanged after 48 hours of storage under the different conditions. Changes in percentage milk protein were also minor. Keeping quality in terms of total counts and dye reduction times, were poorest under shelf storage and best under refrigeration. Sealing the samples resulted in better keeping quality.

Two feeding and digestibility trials were carried out to investigate the effects of groundnut cake (GNC) supplementation on feed intake, DM digestibility, nutrient utilization and liveweight gain of three breeds of cattle fed on all-roughage rations (hay and fresh grass) of Cynodon nlemfuensis var robustus. The results showed a decrease in mean DM intake of the basal ration by approximately 13.14%; 1.9% and 6.4% and an increase in total dry matter intake (basal + GNC supplement) of approximately 0.42%), 11.56% and 11.04% for the indigenous, crosses and exotic animals respectively. The results also showed non-significent increases in the apparent digestibilities of the nutrients. Both the total Digestible Nutrients (TDN) kg/W0.75 and Metabolizable Energy (ME) Kcal/W0.75 intake by the three breeds of cattle were increased with supplementation and mean daily liveweight increased by 18.92%, 13.15% and 16.27% respectively.
