The experiment was carried out to evaluate the ingestive behavior of sheep fed diets containing cocoa meal. Sixteen Santa Inês female sheep, no-pregnant, no-lactating, averaging 25 kg of body weight and 12 months of age, maintained in individual barns were used. The cocoa meal was fed in the concentrate at the levels of 0, 10, 20 and 30%, and as forage was cassava aerial part hay. The diets were offered in total mixed ration, in 50:50 forage:concentrate ratio. Feeding, ruminating […]

The potential performance of lambs and ewes from the Suffolk breed in pasture of Tifton grass 85 (Cynodon spp.) and ryegrass (Lolium multiflorum) was evaluated in different production systems: lambs weaned with 60 days and kept in pasture; lambs with ewes and kept in pasture; lambs with ewes and kept in pasture with creep feeding; feedlot confined lambs with alfalfa hay + balanced ration. The treatments were applied when the lambs reached 60 days of age until slaughter time, at […]

The objective of this trial was to study the effects of enramycin and sodium monensin administration on total digestibility of diet nutrients and digestible dry matter intake in bovine. Twelve non-pregnant and non-lactating cows (675 kg ± 63 BW) were randomly assigned to three treatments: control group, enramycin-treated group or monensin-treated group. Animals received a diet containing 60% of concentrates (corn, soy bean meal and minerals) and 40% of forage (sugarcane). Treatments were 20 mg/animal/day of enramycin or 300 mg/animal/day […]

The objective of this research was to study the effects of enramycin and sodium monensin administration on dry matter intake, ruminal fermentation and alimentary behavior in bovine. Twelve non-pregnant and non-lactating cows (675 kg ± 63 of BW) were randomly assigned to three treatments: control group, enramycin treated group or monensin treated group. Animals received a diet containing 60% of concentrates (corn, soybean meal and minerals) and 40% of forage (sugarcane). Treatments were 20 mg/animal/day of enramycin and 300 mg/animal/day […]

The experiment was carried out with the objective to evaluate the nutrient intakes and milk production and composition of lactating cows fed with rations containing different levels (0; 12,5; 25,0; 37,5 and 50.0%) of spineless cactus (Opuntia ficus Mill) and urea in substitution to the tifton grass hay. Five cows was distributed 5 × 5 Latin square experimental design. The dry matter and organic matter showed a quadratic effect with the inclusion of spineless cactus and urea. The crude protein […]

The objective of this work was to evaluate the effects of the use of maniçoba silage (Manihot glaziovii Muell. Arg.) in different forage:concentrate ratio (30:70; 40:60; 50:50 and 60:40%) in milk composition, fatty acids profile and sensorial characteristics of Moxotó dairy goat milk. Eight multiparus goats were used, with approximately 60 days postpartum and about 44 kg on average, in a 4 × 4 Latin square design, with four treatments, four periods and 4 animals. Each period lasted 15 days […]

The effects of cottonseed and sunflower oil supplementation on milk composition were tested using crossbred Moxotó goats. Experimental diets were as follows: control, without addition of oil; addition of 3% cottonseed oil; 5% cottonseed oil; 3% sunflower oil and 5% sunflower oil (%DM). Ten confined lactating goats were allotted to a double Latin square experimental design (5 × 5). Each period was comprised by 12 days of adaptation to the diet and three days of sampling in each period. Cottonseed […]

This study evaluated the effects of the inclusion of a yeast culture (Saccharomyces cerevisiae 1026) on the parameters of ruminal fermentation of beef cattle. Ten rumen fistulated 1/2 Red Angus 1/2 Nellore steers confined in individual pens were fed a diet containing 50% sorghum silage and 50% concentrate (%DM) containing peleted soybean hulls, sorghum grain, urea and mineralproteic premix. A completely randomized design was used to compare diets with or without Saccharomyces cerevisiae (1 g/100 kg of live weight) on […]

The intake and digestibilility of the nutrients of diets containing palisade grass (Brachiaria brizantha cv. MG4) hay of low quality and different protein levels were evaluated. The evaluated treatments were control (only hay) and hay with crescent addition, by rumen infusion, of the mixture containing ammonium sulphate, casein end urea (0.5:1.0:4.5) in way to elevate in +2, +4, +6 and +8% the CP level in the diets. A Latin square experimental design with five levels supplementation, five animals and five […]

The effects of energy levels in multiple supplements on productive performance and nutritional parameters were evaluated of finishing beef cattle grazing palisade grass (Brachiaria brizantha cv. Marandu), during the rainy to dry transition season. For the performance evaluation, 24 crossbred bulls, 18 month old and 330 kg of initial body weight (BW), were distributed to a completely randomized design, in four paddocks of 1.5 ha each. Four treatments were evaluated: mineral mix (MM) and corn and whole soybean grain based […]
