1. Roughage-free finishing diet based on whole corn grain and a mixture of additives for Nellore heifers
ABSTRACT This study was carried out to evaluate the effect of a blend of additives (choline, methionine, selenium, and organic zinc) on performance, feed efficiency, rumen parameters, and carcass traits of Nellore heifers finished with roughage-free diet. Nellore heifers (n = 36; average BW = 244±24.1 kg; average 24 months of age) were maintained in a feedl

2. Effect of the addition of protected fat from palm oil to the diet of dairy sheep
ABSTRACT The objective of this study was to evaluate the effect of protected fat from palm oil on body weight and milk production and composition of lactating Lacaune ewes. Four treatments (0, 20, 40, and 60 g kg−1 as fed) of protected fat from palm oil were used to feed nine animals in each group. Isoproteic and isoenergetic diets were formulated and adju

3. População de protozoários ruminais em novilhos zebuínos alimentados com ou sem volumoso
ABSTRACT This study aimed to quantify and identify the profile of the rumen protozoa population of beef steers fed with or without roughage. Nellore crossbred steers raised in extensive system on lignified tropical pastures with mineral supplementation and steers confined for 60 days only receiving pelletized concentrate and whole corn kernels were evaluated

4. Performance and digestibility of steers fed by-product of fresh passion fruit or sorghum silage, with and without concentrate supplementation
ABSTRACTThe objective of this study was to evaluate the nutritive value of passion fruit by-product for cattle, contrasting the results with those found with sorghum silage. Four treatments were then constituted, comprising the combinations of the two roughages and the two levels of supplementation (with or without), in a completely randomized design with fo

5. Methane production of two roughage and total mixed ration as influenced by cellulase and xylanase enzyme addition
In recent decades supplementation of animal feeds with exogenous fibrolytic enzymes has substantially improved digestibility and animal performance. However, information related to associated methane production is limited and inconsistent. This study evaluated the effect of cellulase and xylanase enzymes on in vitro methane production of Eragrostis curvula h

6. Effects of dietary brown propolis on nutrient intake and digestibility in feedlot lambs
The present study tested brown propolis in crude or extract form as a feed supplement for feedlot lambs to identify the type that most improves in vivo nutrient digestibility. Digestibility was assessed by both total fecal collection and internal markers and the results obtained by these techniques were compared. The completely randomized design was used to

7. Produção, composição do leite e desempenho reprodutivo de ovelhas Santa Inês alimentadas com rações contendo óleo de canola ou linhaça / Milk yield, milk composition and reproductive performance of Santa Inês ewes fed diets containing canola or linseed oil
The objective in this study was to evaluate the effect of the addition of canola oil (CO) or linseed oil (LO) on milk production and composition and reproductive performance of Santa Inês ewes. In the experiment I, 33 Santa Inês ewes were fed diets containing 50% of roughage (Cynodon dactylon hay). Experimental diets included a control (no oil) and two rem

8. 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

9. Performance, carcass traits, meat quality and economic analysis of feedlot of young bulls fed oilseeds with and without supplementation of vitamin E
The objective of this research was to evaluate average daily gain (ADG), carcass traits, meat tenderness and profitability of keeping cattle fed different oilseeds and vitamin E in feedlot. A total of 40 Red Norte young bulls with initial average body weight of 339±15 kg were utilized. The experimental design was completely randomized in a 2 × 2 factorial

10. Production and quality of milk from Mantiqueira dairy cows feeding on Mombasa grass pasture and receiving different sources of roughage supplementation
Production and quality of milk from dairy cows grazing exclusively on Mombasa grass pasture, during the spring-summer period and fed roughage supplementations, during the autumn-winter, were evaluated in two consecutive years. The pasture of 11.4 ha was divided into 57 paddocks of 2,000 m² each, including three replications with 19 paddocks each. The pastur

12. Efeito da suplementação volumosa e mineralizada mais vermifugação no desempenho de ovinos e caprinos. I. Performance reprodutiva.
Os efeitos da suplementacao volumosa, durante o periodo critico e da mineralizacao mais vermifugacao, foram estudados em ovinos e caprinos, em um experimento realizado na Fazenda Periperi, Nordeste da Bahia, de junho de 1977 a maio de 1980. O trabalho envolveu 125 matrizes caprinas Sem Raca Definida (SRD) e igual numero de ovelhas Morada Nova, distribuidas,
