| ABSTRACT The objective was to evaluate the intake, nutrient digestibility and nitrogen balance in sheep fed diets containing elephant grass (Pennisetum purpureum Schum) silage containing 0; 7; 14 and 21% cottonseed cake. Twenty Morada Nova sheep were used in a completely randomized design with four treatments and five replicates. The diets were isoproteic, isoenergetic and isofibrous. There was no effect of cottonseed cake levels on nutrient intake and digestibility coefficient of ether extract. The digestibility coefficients of dry matter, organic matter, crude protein, total carbohydrates and non-fiber carbohydrates presented a linear reduction with the levels of cottonseed cake varying from, respectively, 537.97 to 421.21; 566.54 to 446.42; 595, 38 to... |

| Animals on pasture generally show higher feed efficiency as a result of the use of antibiotics. This study evaluated the effect of the antimicrobials salinomycin and/or virginiamycin on production and the ruminal parameters of supplemented dairy cows grazing on Panicum maximum cv. Tanzania. Twelve Holstein/Zebu multiparous cows were used, distributed in three Latin squares, one for the evaluation of ruminal parameters, and the others for production parameters. Cows on pasture were fed 50 % of their estimated intake with corn silage and concentrate supplements containing salinomycin, virginiamycin or a combination of additives, in doses of 120 and 150 mg kg−1, respectively. There were no differences in milk production and composition, energy and nitrogen... |

| Soybean hulls (SH) are an alternative fiber source that may be used to maintain neutral detergent fiber (NDF) concentration while increasing the energy concentration of ruminant diets. The objective of this experiment was to determine the effects of replacing coastcross (Cynodon sp.) hay NDF by SH NDF on the apparent digestibility of nutrients and nitrogen balance of Santa Inês ram lambs. Twenty-four animals (42.5 ± 3.6 kg of body weight and six months old) were placed in metabolism crates and assigned in a randomized complete block design defined by body weight (BW). Experimental diets provided a similar concentration of NDF (52%) and crude protein (15%). Hay NDF from a 70% roughage-based diet was replaced with SH NDF by 33%, 67%, and 100%, resulting in... |

| This study was performed in order to evaluate the effect of dried yeast from sugar cane when replacing soybean meal in dairy heifers’ diets. Twenty-four heifers, with an initial body weight (BW) of 178 kg, were distributed in a completely randomized design. The treatments were four levels of inclusion of dried yeast from sugar cane replacing to soybean meal (0, 33, 67 and 100% on a dry matter (DM) basis). While there was no difference in DM, neutral detergent fiber (NDF), metabolizable energy or roughage intakes, the intakes of non-fiber carbohydrates and concentrate were increased. The crude protein intake decreased according to the dried yeast from sugar cane when replacing soybean meal. The digestibility coefficients of DM and NDF showed no difference.... |

| This study evaluated the effect of using fresh sugar cane, sugar cane silage with or without Lactobacillus buchneri, and burnt sugar cane silage with or without L. buchneri on ingestive behavior, nitrogen balance and synthesis of microbial nitrogen compounds of dairy cows. Five ¾ Holstein x Gir crossbred cows, assigned to a 5 x 5 Latin square design, were given diets with a 60:40 forage: concentrate ratio on a dry matter basis, to meet an average body weight of 550 kg and production of 15 kg of milk per day. The treatment with fresh sugar cane showed higher values (p < 0.05) for dry matter feed efficiency (3,133.3 vs 2,234.47 g DM h-1) and rumination (1,642.3 vs 1,222.93 g DM h-1) compared to the silages. There was a shorter total chewing time (58.7 vs... |

| Nutrition values of silages from different sorghum cultivars are evaluated. Five 26-kg castrated crossbred lambs, housed in pens equipped with feces and urine collectors for the study of their metabolism, were employed in a 5 x 5 Latin square experimental design. Treatments consisted of silage from five different sorghum cultivars: IPA 1011 and IPA 2564 (grain sorghum), IPA 2502 (dual purpose sorghum), IPA FS-25 and IPA 467 (forage sorghum). Protein level was corrected to 12% by adding a mixture of urea: ammonium sulfate (9:1). Treatments IPA 1011, IPA 2564 and IPA 2502 provided high intake of dry matter, total carbohydrate and total digestible nutrients, and low intake of neutral detergent fiber. Cultivars IPA 1011 and IPA 2564 provided high apparent... |

| ABSTRACT Leaves of babassu may be used in diets for goats under maintenance, however, it is a low-quality roughage due to its high fiber content. The chemical treatment by ammonia causes reduction in the proportion of the cell wall, in addition to providing non-protein nitrogen for the microbial protein synthesis in the rumen. Babassu palm hay ammoniated with 4% urea (BHAU4%) was evaluated in this study as a substitute for guinea grass hay in the maintenance diets of goats in terms of intake, digestibility in vivo, and the partitioning of energy and nitrogen compounds. Twenty Anglo-Nubian male goats were used in a randomised block design with four treatments (diets containing 0, 33, 66, or 100% BHAU4%) and five replicates (animals/block). The chemical... |
