26. Urea in sugarcane-based diets for dairy cows
We evaluated the effect of adding four levels (0, 4, 8 and 12 g/kg, as fed) of a mixture (9:1) of urea and ammonium sulfate (UAs) to sugarcane on feed intake and digestibility, productive performance and metabolism of nitrogen compounds of dairy cows. Twelve multiparous Holstein cows (12.6±0.5 kg/d of milk, 225±90 days in milk) were distributed in three 4

27. Prebiotic inulin: Useful dietary adjuncts to manipulate the livestock gut microflora
In recent years, there has been a growing appreciation on the relevance of gastrointestinal microflora in both ruminants and non-ruminants owing to revelation of their role in several physiological functions including digestion, nutrient utilization, pathogen exclusion, gastrointestinal development, immunity system, gut gene expression and quality of animal

28. Soybean meal or cotton by-products associated with urea as source of nitrogen in the diet of lactating goats
The objective of this study was to evaluate the influence of sources of nitrogen on the intake and digestibility of nutrients and production and chemical composition of goat milk. Soybean meal (SBM), soybean meal + urea (SBM+U), cottonseed meal + urea (CM+U), cottonseed cake + urea (CC+U) and whole cottonseed + urea (WC+U) were used, representing the differe

29. Effect of tanniniferous plants and essential oils on methane emission in ruminants / Efeito de plantas taniníferas e óleos essenciais sobre a emissão de metano em ruminantes
Tannins and essential oils are secondary metabolites that may be used as natural modifiers of rumen fermentation to reduce the ruminants\ methane (CH4) emission. To study the application of tannin-rich plants from Egypt and Brazil, as well as essential oils that are available in international trade, three studies were conducted at Animal Nutrition Laboratory

30. CASHEW NUT MEAL USED AS FEED SUPLEMENT IN DIETS FOR LAMBS / UtilizaÃÃo do farelo de castanha de caju como suplemento alimentar em dietas de ovinos
The effects of supplementation with cashew nut meal (CNM) for sheep fed Tifton 85 (Cynodon sp.) grass hay as exclusive forage were evaluated on intake, digestibility, nitrogen balance and ingestive behavior of these animals. For this, we used twenty four male sheep, non-castrated, without defined breed and with an initial body weight (BW) of 16.2 + 3.1 kg an

31. Grão de soja em suplementos múltiplos para novilhas de corte em pastejo / Soybean in multiple supplements for grazing beef heifers
This dissertation was prepared from two experiments with beef heifers submitted to different supplementation strategies on pasture. In the first experiment aimed to evaluate the effect of replacing soybean meal by soybean at different levels in multiple supplements on the nutritional characteristics and productive performance of heifers grazing in Uruchloa d

32. Substituição do farelo de soja por fontes de nitrogênio não-protéico em bovinos Nelore / Replacement of soybean meal for non protein nitrogen on Nellore steers
Capítulo 2: Estudos vêm sendo realizados na tentativa de se avaliar os efeitos da manipulação da nutrição protéica, devido à sua importância no metabolismo e desempenho de bovinos. O presente estudo teve como objetivo identificar a melhor fonte de nitrogênio não-proteico (uréia, uréia de liberação lenta ou a combinação destas) em substituiç

33. Productive performance and efficiency of utilization of the diet components in dairy cows fed castor meal treated with calcium oxide
The effect of replacing of 0; 0.33; 0.67 and 1.0 (kg/kg) of soybean meal (SBM) by undecorticated castor seed meal treated with calcium oxide (CMT - 60 g/kg) was evaluated on performance and efficiency of nutrient utilization in dairy cows. Sixteen Holstein and crossbred cows were distributed in four 4 × 4 latin squares. Animals received concentrated feed at

34. Metabolism and ruminal parameters of Holstein × Gir heifers fed sugarcane and increasing levels of crude protein
The objective of this study was to evaluate the effect of increasing levels of crude protein (CP) in the diet (13, 15, 19 and 22 g/100 g of dry matter, DM) on the metabolism and ruminal parameters of crossbred heifers fed forage sugarcane. Four crossbred Holstein × Gir heifers of average initial weight of 200 kg and average age of 14 months were used. The e

35. Intake and performance of feedlot cattle fed diets based on high and low Brix sugar cane with or without calcium oxide and corn silage
The objective of this study was to evaluate low and high Brix diets, treated or not with 5 g of calcium oxide per kg of natural matter, and corn silage on intake, digestibility and performance of beef cattle. Forty cattle with initial body weight (BW) of 350 kg were used: five composed the control group, 30 were distributed into random blocks (control) and t

36. Intake, digestibility and nitrogen use efficiency in crossbred F1 Holstein × Zebu grazing cows
The objective of this study was to evaluate intake, digestibility and nitrogen (N) compounds use efficiency in F1 Holstein × Zebu grazing cows. Eighteen crossbred cows (six Holstein × Gir, six Holstein × Guzerat, and six Holstein × Nellore) were used in the experiment, constituting three experimental treatments in simple random samples, under the same fe
