The objective of this study was to evaluate the intake and digestibility of silages containing pineapple pulp and coast-cross hay, with or without addition of urea, and the recovery of the markers chromium oxide (Cr2O3), indigestible neutral detergent fiber (iNDF), indigestible acid detergent fiber (iADF), and indigestible dry matter (iDM), in a digestibility assay, in sheep. Treatments were as follows: two levels of pineapple pulp (818 and 758 g kg−1) and two levels of urea (with and without urea), in […]

The objective of this study was to find the best level of inclusion of crude glycerin (0, 60, 120, and 240 g kg−1 of dry matter of diet) in substitution of pearl millet in a feedlot diet. Twenty-eight Nellore young bulls with mean age of 18 months and average weight of 357±23.56 kg were used. The animals were distributed in a completely randomized design with four treatments and seven replications. The intakes of dry matter, crude protein, neutral detergent fiber, […]

The objective of this study was to evaluate the feeding behavior and feedlot productive performance of dairy-origin steers fed for 84 days ground pearl millet grain-based diets with 0, 120, 240, 360, and 480 g kg-1 of babassu mesocarp bran (BMB) and a standard diet based on ground corn. Thirty Holstein-Zebu steers with average initial body weight of 371.02±27 kg were used. The experimental design was completely randomized, with five replications. Dry matter intake showed better fit with the quadratic […]

The majority of sheep milk produced in the world is transformed into cheese. Feeding is a major factor affecting the quality of sheep milk and, therefore, of sheep cheese. Because fat is the main compound of cheese, this review gives an update on the effects of feeding and nutrition on milk fat content and deeply discusses feeding strategies aimed at increasing the levels of healthy fatty acids (FA), such as conjugated linoleic acid and omega-3 FA, in milk and cheese […]

This experiment was conducted to evaluate the protein and carbohydrate fractions, and to estimate the in situ rumen degradation kinetic parameters of Brachiaria decumbens grass silage with inclusion of rice bran. Five rice bran inclusion levels were tested: 0, 10, 20, 30 and 40% of the natural matter, distributed into a completely randomized design with five replications. The brachiaria grass was obtained at 60 days of regrowth by cutting the forage at 10 cm from the soil and ensiling it […]

Two studies were conducted to evaluate the effects of crude glycerin on feed intake, performance, carcass characteristics, and total digestibility of Nellore bulls. In experiment 1, cattle (n = 30) were fed a control diet without crude glycerin and diets containing 7.5, 15, 22.5, and 30% crude glycerin, for 103 d. Animals were harvested and data of carcass characteristics were collected. In experiment 2, a digestibility trial was performed using indigestible acid detergent fiber (iADF) as internal marker, and five […]

The objective of this experiment was to evaluate the effects of adding monoammonium phosphate (MAP) in high concentrate diets containing citrus pulp on feedlot lamb performance and carcass characteristics. Twenty four Santa Ines lambs (26.4 kg of initial body weight and 125 d old) were penned individually and used in a randomized complete block design according to body weight and age at beginning of the trial. Diets were formulated to provide a similar amount of crude protein and contained 70% […]

The experiment was carried out to evaluate the ingestive behavior of sheep fed diets containing elephant grass silage with different additives. Twenty sheep non-castrated male kids were used in a randomized complete design, with four treatments and five replications. The treatments were: elephant grass silage (control); elephant grass silage (75%) + coffee hulls (15%); elephant grass silage (75%) + cocoa meal (15%) and elephant grass silage (75%) + cassava meal (15%). The additives were added at ensilage moment was realized […]

The objective of this trial was to determine the effects of feeding diets containing citrus pulp on carcass characteristics and meat quality of feedlot lambs. Thirty-two Santa Ines lambs were distributed in a complete randomized block design according to body weight and age at the beginning of the performance trial. Lambs were fed diets containing 90% concentrate (corn and/or citrus pulp, soybean meal and minerals) and 10% coastcross hay (Cynodon spp). Citrus pulp was added at levels 23.7, 46.1 and […]

The objective of this work was to evaluate the carcass characteristics and “buchada” dressing of goat fed with diets with 0.0, 8.9, 19.8, and 31.7% of rough wheat bran (RWB) replacing corn. Twenty-four crossbred male goats, with initial 20 kg LW, in individual cages, allotted to a completely randomized experimental design with four diets and six replications, during 74 days. Hot and cold carcass weight and dressing decreased linearly, the slaughter live weight (27.85 kg), fasting losses (4,02%), cooling losses […]
