Two levels of concentrate (20 and 40% dry matter) and presence or absence of propolis ethanolic extract (PEE) in the diet at 30% w/v were evaluated in this study. The intake and apparent digestibility of nutrients, milk production and composition, live weight, feed efficiency and concentrate use for milk production were evaluated. Eight Holstein cows were distributed in two 4 × 4 Latin squares. The experiment was carried out in four 21-day periods, the first fourteen days were for the […]

The effects of the addition of 15% of different addictives (coffee hulls, cocoa meal and cassava meal) to green elephant grass forage, in natural matter basis (weight/weight), at the ensilage moment on the consumption of nutrients and the performance of twenty Santa Inês sheep under feedlot system were evaluated. The animals had 5.0 months of age, initial weight of 22.27 ± 3.24 kg and final weight of 28.6 ± 3.78 kg. The treatments were: T1 = elephant grass ensiled without […]

This study was conduced to evaluate the energy sources, rich in starch or fiber in multiples supplements on performance and nutritional characteristics of finishing crossbred steers in the dry/rainy transition season, grazing Brachiaria decumbens Stapf. The experimental area was divided into 5 paddocks with 2.0 ha each, with dry matter availability of 4.309,4 kg/ha. Twenty-four castrated crossbred steers were used, initially 24 month old and 314.46 kg. For each animal, one of the five treatments was randomly applied: mineral mixture […]

Four Zebu × Holstein steers were fistulated in rumen, abomasums and esophagus, with 430 kg of live weight grazing in four paddocks of Brachiaria decumbens (.40 ha), feed supplements were used to evaluate intake, digestibility, pH and ammonia ruminal concentration, nitrogen in serum and urine and microbial yield. The animals received 4.0 kg/animal/day of supplement based on grounded corn grain, cottonseed meal, mineral mix (MM), ammonium sulfate and urea in four levels (0, 1.2, 2.4 and 3.6%) as fed basis. […]

The objective of this work was to test the efficiency of enriched and purified lignin, Lipe®, as external indicator in order to estimate the apparent digestibility of the nutrients in equine diets, compared with the total feces collection and the chromic oxide methods. Six female Mangalarga Marchador with average of two years of age and average weight of 331 kg were used. The diet was alfalfa hay, commercial grain and mineral salt. The experimental period was of 29 days, the […]

The effect of feeding, in the rainy season, multiple supplements formulated with different sources of protein on nutritional characteristics of growing beef cattle was evaluated. Five Holstein-Zebu crossbred steers with initial live weight of 300 kg, fistulated in the esophagus and in the rumen, were assigned to five paddocks (0.3 ha) of Brachiaria decumbens in a 5 × 5, incomplete Latin square design, with 5 supplements and 4 periods in 4 (14 days). Supplements evaluated were based on soybean meal […]

Two trials were conducted to evaluate losses of Marandu grass silages using different additives. The fermentation profile and aerobic stability of the silages were evaluated on the first trial. The followings silages were evaluated: 1 – Marandu grass (Control), 2 – Marandu grass plus L. plantarum and Propionibacterium, 3 – Marandu grass plus L. buchneri, 4 – Marandu grass plus 0.1% of sodium benzoate. On the second experiment, it was utilized nine castrated Nellore steers (Body weight 350 ± 38.9 […]

The effects of multiple supplements with different urea levels on the productive performance and nutritional characteristics, for finishing beef cattle kept in deferred pasture of palisade grass (Brachiaria brizantha cv. Marandu) in the transition period of rainy to dry season were evaluated. The estimated dry matter availability of the pasture ranged from 16,360 to 9,358 kg/ha. In the performance trial, 20 crossbreed bulls, 20 months old and initial 376 kg BW were used. The animals were grouped in lots of […]

The objective of this study was to evaluate the performance and the gross margin of profit of lambs finished in feedlot. Thirty-two no castrate male lambs from the genotype Santa Inês and crossbred Dorper × Santa Inês and two body condition, intermediate and fat, were used. The lambs were 16 Santa Inês (SI) and 16 ½ Dorper × ½ Santa Inês (DpSI), with average 103 days old and 20.0 kg BW. The lambs were full fed ration with 30% of […]

This research was carried out to evaluate the intake, total and ruminal digestibilities, microbial efficiency synthesis, nitrogen balance (NB) and ruminal parameters of beef heifers, fed sugarcane treated or not with calcium oxide (CaO – 1.0%) and different concentrate levels (CL), in feedlot. Six animals (170.0 kg BW) were allotted to a 6 × 6 Latin square design in a 2 × 3 factorial arrangement (sugarcane in nature treated or not with 1.0% CaO and three CL 0.0, 0.5 and […]
