The objective of this study was to evaluate the effects of feeding sugarcane bagasse, obtained by extraction of sugar using diffusion (BINdif) or conventional milling (BINmoa) method, as a fiber source associated with bagasse treated under pressure and steam (BTPV) on nutrient digestibility and ruminal characteristics in beef cattle. Four Nellore young bulls (380 kg BW), fitted with ruminal cannula, were assigned to a 4 × 4 Latin Square design. Combination of bagasse in a 50:50 (concentrate:roughage) experimental rations were: […]

The effect of ammonization of elephant grass and the partial substitution of the standard concentrate based on corn and soybean meal by concentrates containing cocoa meal or palm cake on sheep performance was evaluated. A total of 18 Santa Inês male sheep, with average 22.6 kg BW, was allotted to a completely randomized design in a 2 × 3 factorial arrangment with three replications. The experimental period consisted of 77 days, with 14 days for adaptation and three periods of […]

Thirty six mid lactating Holstein cows, 123 days in milk (DIM), were used to evaluate the substitution of ground corn (GC) by soybean hulls (SH) for in total mixed diets containing corn silage as the main forage source and citrus pulp as part of the energy source. The replacement of 0, 10 and 20% of ground corn by soybean hulls in total mixed diets (%DM) were evaluated: SH 0 – 0% SH and 20% GC, CS 10: 10% SH and […]

The objective of this trial was to investigate the effects of feeding corn with different particle size (coarse vs. fine grinding) plus dried citrus pulp or soyhulls on performance of lactating dairy cows. Thirty-two mid lactating Holstein cows averaging 160 days in milk were randomly assigned to eight replicated 4 x 4 Latin squares with a 2 x 2 factorial arrangement of treatments. Animals were fed total mixed rations containing corn silage as the sole forage source. Each experimental period […]

Seventy-two finishing Canchim bulls averaging 318 kg of initial body weight and 18 months of age were assigned to a completely randomized block design to evaluate the effects of replacing ground corn (GC) with dried citrus pulp (CP) on average daily weight gain, dry matter intake, feed efficiency, carcass yield, and Longissimus dorsi fat thickness. Diets contained forage (sugarcane silage) to concentrate ratio of 30:70 and the following levels of CP and GC: 100% GC (CP0), 50% GC + 50% […]

Twelve Holstein-Zebu lactating dairy cows were used to study the effects of different carbohydrate sources and soybean oil on dry matter intake, milk yield, and milk composition. The following carbohydrate sources were used: corn (CO), wheat bran (WB) or citric pulp (CP) with 0 or 2.25% of soybean oil. No significant interactions between soybean oil and carbohydrate sources were observed in this trial. Both dry matter intake (18.4 kg/day) and milk yield (23.5 kg/day) did not differ among carbohydrate sources […]

This work was carried out aiming to evaluate the nutritive value of byproducts of fruit processor. Byproducts of pineapple, west indian cherry (WIC), guava, passion fruit and melon were evaluated. Twenty sheep castrated males, with average weight of 34.5 kg, were assigned to a completely randomized design with five treatments (byproducts) and four replications. Dry matter intakes (DMI) of byproducts of guava, passion fruit and melon by the animals were similar but higher than WIC byproduct. The highest crude protein […]

The effects of the replacement of corn silage by orange peel silage were studied on the intake of nutrients, production and quality of the milk of Holstein dairy cows. A 4 x 4 Latin square design with four replacement levels (0, 25, 50 or 75% DM) of corn silage by orange peel with forage to concentrate ratio of 50:50 were used. The replacement levels did not affect the percentage of milk fat and milk protein, however the nutrient intake and […]
