title: Protein-energy supplementation frequency on ruminal variables, intake and digestibility in steers receiving low quality hay

description: Abstract The aim was evaluated the effect of reduce in protein-energy supplementation frequency on nutrients intake, forage digestibility and degradability, as well as, ruminal pH and ammonia nitrogen (N-NH3) concentration in beef cattle receiving low-quality hay. A 4 x 4 Latin square design were used. Four steers were fed with low-quality hay and subjected to four treatments: no supplementation (control); protein-energy supplementation with 0.82% of body weight (BW) offered three times per week (3WK); 0.49% of BW offered five times a week (5 WK), and 0.35% of BW offered seven times per week (7 WK). The use of protein-energy supplementation increased intake of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), ether extract (EE), non-fibrous carbohydrates (NFC) and the digestibility coefficients of CP, EE, and NFC. However, no differences in DM and NDF degradation visit the website to get the how were observed between treatments in the evaluated hay. Supplementation did not alter ruminal pH, but the N-NH3 concentration was highest in treatment 7WK. Reduction in protein-energy supplementation frequency of daily to 3WK or 5WK does not negatively affect intake, digestibility and degradability of nutrients in beef cattle receiving low quality hay.

title: Chemical composition in soybean silages with inoculant and molasses

description: Abstract Chemical composition was assessed in soybean silages without any additive (control), with a microbial inoculant (I), with I + molasses (I+M), and with molasses only (M). Soybean plants were harvested at the reproductive 6 (R6) stage and ensiled in 2 kg-capacity PVC laboratory silos. The SIL ALL C4 inoculant produced by Alltech Brazil was used in combination with or without 2.5% molasses added to the natural matter base. A 4 × 6 factorial arrangement (4 additives × 6 fermentation periods) in a completely randomised design with 3 replications was used. The assessed fermentation periods were 1, 3, 7, 14, 28, and 56 days. Excluding the dry matter and crude protein contents it was observed an interaction effect (P&lt;0.05) between the additive and fermentation periods in the silages. It was observed higher average values of dry matter, equal 290.02 g kg-1, and crude protein, equal 151.28 g kg-1, to I+M and M silages, respectively. It was observed lowest values (P&lt;0.05) to neutral detergent insoluble nitrogen (NDIN) and acid detergent insoluble nitrogen (ADIN) contents in I+M silages, equal 180.47 and 125.07 g kg-1, respectively. The addition of inoculant associated or not with molasses improved affect the chemical composition of soybean silages.

title: Wafer-type biscuit waste in meat-quail diets

description: Abstract Two experiments were carried out to evaluate the nutritional composition and effect of different levels of inclusion of wafer-type biscuit waste (WW) in the diet of European quail on production performance, carcass yield and economic viability. In the metabolizability trial, WW showed 87.45% DM, 4,128.53 kcal/kg GE, 3,833.14 kcal/kg AME, 3,818.92 kcal/kg AMEn, 9.37% CP and 17% EE. The metabolizability coefficients of DM, GE, EE and CP were 93.20, 92.85, 93.01 and 47.16%, respectively. In the performance trial, feed intake decreased linearly (P&lt;0.05) from 22 to 42 and from one to 42 days of age. Weight gain and feed conversion were not influenced (P&gt;0.05) by WW inclusion. The WW inclusion levels did not influence (P&gt;0.05) carcass yield. The diet with 20% inclusion of WW provided the best financial return. Wafer-type biscuit waste can be included up to the level of 20% in quail diets without compromising production performance, carcass yield or the economic viability of the activity.

title: Performance of intact and castrated nelore steers grazing Brachiaria humidicola (Rendle) Schweick (Poaceae) alone and intercropped with forage peanut

description: Abstract This study aimed to assess the performance of intact and castrated beef cattle on the pasture of Brachiaria humidicola alone and intercropped with Arachis pintoi cv. BRS Mandobi. The experiment was carried out from February to June 2016 on the private property of a partner of Embrapa Acre. The experimental design was completely randomized in a 2×2 factorial arrangement, with two sex classes (intact and castrated) and two types of pasture (alone and intercropped). The leaf to stem ratio was high (P&lt;0.05) in the pasture alone. No significant difference was found for stocking rates. Dry matter intake was high (P&lt;0.05) in the intercropped pasture compared to that alone, with means of 8.96 and 6.66 kg/ day, respectively. Animals managed in intercropped pastures had better performance (P&lt;0.05) than those castrated under pasture alone. Nelore steers castrated at 20 months of age, managed under intercropped pastures, showed similar productive performance (P&gt;0.05) to intact animals.

title: Types of sterilization in feed containing different lipidic sources for golden hamster (Mesocricetus auratus)

description: Abstract The Golden hamster has been gaining significance as a new experimental biomodel, finding use as a reliable diagnostic tool in biomedical research and for zoonosis. Authentic data in terms of digestibility, interactions among raw materials and essential nutrients, besides the influence exerted by various sterilization processes on animal behavior remain unclear. We aimed to assess the influence of sterilization, via autoclaving and irradiation, of pellet feeds prepared using salmon or linseed oil on the digestibility and plasma biochemical parameters in Golden hamsters. Randomized evaluations were conducted on 36 adult male Golden hamsters (Mesocricetus auratus), distributed in six treatments and six replications, namely: common salmon oil; radiated salmon; autoclaved salmon; common linseed oil; radiated linseed and autoclaved linseed. A remarkable effect of the sterilization was evident on the digestibility and protein solubility of the feed, which was lower for autoclaved diets. There was also a significant effect on blood parameters. Animals fed diets containing linseed oil showed lower blood glucose compared to the others. Thus, the inference reached was that while salmon and linseed oil can be used in laboratory hamster feeds, autoclaving disturbs the nutritional quality of the rations.

title: Ingestive behavior and feeding preference of goats reared in degraded caatinga

description: Abstract This study aimed to assess the ingestive behavior and feeding preference of goats reared in degraded Caatinga (dry tropical forest) during three seasons: transition (rainy-dry), dry, and rainy seasons. The experiment was carried out at the UFPB Experimental Station in São João do Cariri, PB, Brazil. Six male goats kept on pasture with an area of 3.2 hectares were used. The animals were assessed through continuous visual observation. The experimental design was completely randomized, with three treatments (rainy-dry, dry, and rainy seasons) and six replications (animals). Means were submitted to the Tukey test at a 5% level. The time www.revistas.ufq.br/vet spent by animals during the transition season (rainy-dry) had to cite in the article page. similarities for the selected grasses, herbaceous/sub-shrub plants, litter, and shrub/ tree plants, except for bromeliads and cacti. The animals spent longer grazing time consuming grasses at the rainy season. During this season, marmeleiro (Croton hemiargyreus Mill. Arg.) was the most selected species in relation to catingueira (Caesalpinia pyramidalis Tul.) and pereiro (Aspidosperma pyrifolium Mart.). The time spent for grazing activity during the transition season (rainy-dry) was longer than the rainy and dry season. Goats reared extensively in the Caatinga have high plasticity in their eating habits and can behave as grazing or browsing animals.

title: Calving month and calf sex on the production and efficiency of herds

description: Abstract The calving period influences productivity and reproductive efficiency the herds. The objective of this study was to evaluate two calving months (October and November) and their effect on the efficiency of a breeding herd for three consecutive years. A total of 298 Braford cows were evaluated at three, four, and five years of age, with their calves early-weaned at 148 days of age. The performance characteristics of the cow/calf pairs were evaluated with the calving month and calf sex as the independent variables. The animals were kept as a single group for the three years of observation. Cows calving in November were heavier and had a higher body condition score at calving. Cows calving in October were heavier and produced heavier calves at weaning. Male calves were heavier at birth and weaning than females (30.8 vs 28.6 kg and 118.9 vs 114.7 kg, respectively). The pregnancy rate was 82.35 and 69.23% for cows calving in October and November, respectively. Calving intervals were shorter in cows calving in November. Cows calving in October were more efficient compared with those calving in November, with a higher actual fertility rate. The production of kilograms of the calf/cow pair was higher for cows calving in October.

title: Paprika and/or marigold extracts improve productivity and yolk color in egg-laying quails

description: Abstract This study was conducted to evaluate the effects of paprika and marigold extracts on the productivity of Japanese quails, quality and sensorial analysis of eggs. Japanese quails were allocated in a completely randomized design and factorial arrangement 2 × 2 + 1, and four replicates. Diets were formulated based on: 1) corn (control), and 2) sorghum (S) without pigments, 3) S + 0.06% paprika extract (PE), 4) S + 0.01% marigold extract (ME), and 5) S + 0.06% PE and 0.01% ME. There was no effect of the control and factorial interaction on feed intake, egg-laying rate, or egg mass; however, the feed: gain ratio was lower among quail fed with diets containing both extracts. The inclusion of PE and ME in the diets improved the feed: gain ratio and yolk color; the inclusion of PE reduced the feed intake and specific weight of the eggs. Compared to the control, treatments based on sorghum or sorghum + PE led to a difference in egg taste and yolk color in the sensorial visit the website to get the how analysis. It was concluded that paprika and marigold extracts could be included in quail diets because of improvements in feed: gain ratio and yolk color.

title: Nesting behavior of stingless bees

description: Abstract Native bees, besides excellent producers of honey, lend a great legacy to humanity through their ability to pollinate plants and the consequent preservation of ecosystems. In this interspecific relation, bees are benefited by plant species by the provision of food (nectar and pollen), besides using their branches and trunks for lodging. However, the anthropogenic action has jeopardized the survival of stingless bees, causing irreversible environmental damage in the preservation of natural resources. This study aimed to identify the nesting habits of native bees under natural conditions. Random trails in the Curimataú micro-region of Paraíba allowed identifying nesting sites of indigenous species in their natural habitat. Sixty honeycomb nests were identified in 12 different plant species, being Commiphora leptophloeos the most preferred host (46.66%), with 55% of the entrance holes pointed to magnetic orientations between the Northeast and Northwest; a greater choice by host trees (85%); preference for nesting in host plants with a circumference of 0.98 m in diameter, entrance hole of nests of 7.77 mm in diameter, and height from the ground of 1.52 m. The obtained data showed little variety of stingless bee species in the Curimataú region of Paraíba, especially Melipona subnitida. The species Melipona asilvae, Melipona scutellaris, Partamona seridoenses, and Plebeia sp. should receive special attention not to become extinct in this region.

title: Ruminal degradation of Panicum grasses in three post-regrowth ages

description: Abstract The objective was to evaluate the chemical composition and in situ degradation of Maasai, Mombasa and Tanzania grasses belonging to the genus Panicum, at 22, 34 and 46 days after regrowth. The contents of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were determined. For the evaluation of ruminal degradation, 4 g sample were placed in nylon bags and incubated in the rumen of a fistulated animal, for 6, 24 and 72 h. The experiment had a completely randomized design for chemical composition analysis and a split-split plot completely randomized design for in situ degradation, with means compared by Tukey test at 5%. There was an increase in the contents of DM (+ 1.69%) and NDF (+ 5.06%) (P &lt;0.05) of the grasses at the highest cutting ages with reduction in the CP fraction. The potential degradation (PD) of DM, NDF and CP decreased with advancing age of grasses, with an increase in colonization time (0.69 h) and NDF degradation rate (1.14%/h). The increase in the post-regrowth age of the Massai, Mombasa, and Tanzania grasses increases the acid detergent fiber content and reduces the crude protein content, with a negative effect on the degradation of DM, PB and NDF. The management of these cultivars is indicated at 22 and 34 days post-regrowth to obtain forage with better nutritional value.

title: Influence of gestation length, seasonality, and calf sex on birth weight and placental retention in crossbred dairy cows

description: Abstract The objective of this study was to evaluate the influence of gestation length, season at calving (autumn-winter vs. spring-summer) and calf sex on birth weight and incidence of retained placenta (RP) in crossbred lactating dairy cows. A total of 187 parturitions were evaluated in a commercial dairy farm at Alto Paranaiba region, Minas Gerais, Brazil. Cows that did not release the placental membranes within the first 12 hours after calf expulsion were diagnosed with RP. At birth, calf sex was registered, and birth weight was estimated by using a weighing tape. The incidence of RP was 36.89% (69/187). The mean birth weight of the calves (41.73 kg) did not differ among the calf sexes and seasons of the year at birth (P &gt; 0.05), but the cows with below-average gestation lengths (274.4 days) calved lighter calves. Furthermore, the season of the year at calving and calf sex had no influence on RP incidence (P &gt; 0.05), although a higher incidence of RP was observed in cows that had shorter gestation lengths (49.44%) and calves below-average birth weights (51.76%). In conclusion, cows with shorter gestation lengths produce lighter offspring and have a high predisposition to RP.
