The objective of this study was to evaluate the performance of Texel × Ile de France female hoggets on pearl millet (Pennisetum americanum (L.) Leeke) pastures fed supplementation with cassava meal or corn gluten. It was used a completely randomized experimental design, with three treatments (feed strategies) and two area replications. Feed strategies consisted of supplementation of the pastures with cassava meal or corn gluten in comparison to exclusive pasture. Supplements were given daily at 9:00 a.m. at quantity of […]

Thirty-two multiparous Angus cows at moderate body condition score (3 in a 1-5 scale) received feed supplementation at the beginning of lactation for a short time to determine the effect on milk yield and composition and on performance of cows and calves. Supplementation started on days 22 ± 3.2 after calving. The cows were randomly distributed into two groups (n =16), one group receiving feed supplementation for 35 days (supplemented group), and the other without supplementation (control group). Each cow […]

The objective of this work was to evaluate the nutrient intake and ingestive behavior of growing Santa Inês lambs fed different levels of metabolizable energy (ME). It was used 20 non-castrated lambs at 50 days of age and with 13.00 ± 0.56 kg of body weight. The animals were distributed into four experimental treatments with different levels of metabolizable energy (2.08, 2.28, 2.47 and 2.69 Mcal/kg of dry matter) in a randomized block design with five replications. It was used […]

The objective of this study was to characterize meat quality in Bos taurus and Bos indicus and to determine the influence of finishing system and genetic group on the physicochemical properties of the longissimus thoracis at 24 hours and 10 days post mortem (1ºC). The sample included 160 bulls of the B. taurus (n=75) and B. indicus (n=85) groups, finished either on pasture (n=46) or with grain supplementation (n=114), slaughtered at a carcass weight of 270 to 300 kg. Pasture-finished […]

A total of 672 one day old- female quails was allotted to a completely randomized experimental design, with three treatments (non-trimmed birds; 1/3 of the beak trimmed and cauterized beak), 8 replicates of 28 birds to evaluate the effect of beak trimming and drinking system on productive performance. The birds were beak trimmed at 21 days of age, and at day 35 the weight gain, feed intake, feed conversion and mortality were evaluated. At day 39, 576 quails were transfered […]

The objective of this study was to evaluate environmental thermal conditions in broiler houses with two different ventilation systems and two different litter materials. The experiment was carried out in four 12 m × 10 m broiler houses, internally divided in 4 boxes/poultry house, with 200 birds/pen for four consecutive flocks, each one with a duration of 42 days with 15 days of downtime between flocks. Treatments tested were two ventilation systems (stationary or oscillating fans), and two types of […]

The objective of this work was to evaluate the effects of addition of oil and of levels of supplementation of E vitamin on the boar sperm cryopreservation. It was used 24 Dalboar 85 boars, at 12 to 18 months, distributed in a complete random design, in a 2 × 3 factorial arrangement, with two source of oil (soybean and salmon) and three levels of E vitamin (150, 300 and 450 mg/kg). Semen was collected weekly (1 collection/male), diluted in centrifuge […]

The objective of this work was to evaluate the influence of using silk flower hay replacing corn and soybean meal on physical-chemical and sensorial traits of lamb meat. It was used 32 intact Morada Nova male lambs (12.7 ± 2 kg initial body weigth) on feedlot system, distributed in a completely randomized design with four levels (0, 15, 30 and 45% on dry matter basis). The use of silk flower hay in the diet influenced quality of meat and carcass, […]

The objective of this research was to evaluate the nutritive value of the forage of 12 genotypes of six double purpose (forage and grains) winter cereal species submitted to harvest in the region of Depressão Central in Rio Grande do Sul state. The species and genotypes tested were: wheat (BRS 277, BRS Guatambu, BRS Tarumã and BRS Umbu); black oat (Agro Zebu, UPFA 21 – Moreninha and Commom black-oat); white-oat (UPF 18); rye (BR 1 and BRS Serrano); barley (BRS […]

With the objective of evaluating levels of lactose in diets for piglets weaned at 21 days of age, it was carried out an experiment with 72 animals, with average weight of 6.12 kg, distributed in a completely randomized block design with four diets (0, 4, 8, and 12% lactose), six replicates, and 3 animals per experimental unit. Animals were fed the experimental diets from 21 to 35 days of age and they were fed a lactose-free basal diet from 36 […]
