The aim of this work was to evaluate the effect of replacing concentrate by wet brewer grain on the intake and digestibility of nutrients in goats. It was used five Boer x Saanen crossbreed goats and five Saanen goats randomly distributed in two 5 x 5 latin squares. The diets were composed of 40% of Tifton hay and the other 60% were composed of 0, 25, 50, 75 or 100% of wet brewer grain replacing the concentrate. The intake of […]

The objective of this work was to evaluate the quantitative characteristics of carcasses of Moxotó and Canindé goats finished in feedlots and fed diets of two levels of energy. It was used 40 castrated young goats, 20 from Moxotó breed and 20 from Canindé breed, each one with an average body weight of 15.2 kg. The animals were fed with diets containing 2.20 and 2.71 (Mcal/kg DM). The experimental period lasted 86 days. There was no difference among the barometric […]

This work aimed at determining the influence of roughage proportions and fat source of the diet on characteristics of carcass and comercial cuts of lambs. It was used 24 non-castrated Santa Inês male lambs, ad libitum fed diet with two proportions of roughage (30 and 70%) and fat (no fat, protected fat, and soybean) slaughtered at an avarage body weight of 35.4 kg (± 1.5 kg). Animals fed 30% roughage diet showed the highest weights and carcass yields. The percentages […]

The present study aimed to assess the effect of levels of supplementation with concentrate on the tissue composition of commercial cuts of goats finished in native pasture. It was used 24 non-castrated cross-bred F1 (Boer × SPRD) goats at the age of 120 days, with initial average body weight (BW) of 15.52 kg distributed in four levels of supplementation with concentrated feed (0.0; 0.5; 1.0 and 1.5% of body weight in dry matter) and slaughtered at 25.12 kg; 26.62 kg; […]

It was evaluated the performance and the carcass characteristics of 36 non-castrated male lambs, Santa Inês purebreed and crossbreeds from Dorper × Santa Inês and Texel × Santa Inês, managed in three different systems (intensive, semi-intensive and extensive), slaughtered at 38.41 ± 1.24 kg. It was observed the highest weight gain for lambs reared in intensive system, which also showed the greatest carcass yield. The management systems did not influence carcass measures of animals in intensive system much because of […]

The objective of this work was to evaluate the effects of supplementation with nitrogenous compounds on intake and digestibility in cattle under grazing during dry season. It was used five Holstein × Zebu steers with average initial live weight of 236 kg, kept in five Brachiaria decumbens Stapf. paddocks (0.34 ha). The experiment was carried out according to a 5 × 5 Latin square design, with five supplementation levels and five experimental periods. The supplementation levels were the following: 0; […]

The effects of protein supplementation on degradability of dry mattter (DM), crude protein (CP) and neutral detergent fiber (NDF) and acid detergent fiber (ADF) were evaluated in beef cattle grazing Brachiaria brizantha cv Marandu. It was used four Nelore steers (395 ± 9 kg) fitted with ruminal cannula to evaluate kinetics and degradability of the liquid phase and of the particles. Forage samples were collected in other two steers with esophageal cannula. Supplements with 50, 40, and 30% of crude […]

The objective of this study was to determine the effects of replacing corn by dried citrus pulp on chemical composition and fatty acids profile in longissimus dorsi muscle of thirty-two Santa Ines lambs, slaughtered at average weight of 33 kg at 141 days of age. Lambs were fed a 90% concentrate (ground corn and/or dried citrus pulp, soybean meal and minerals) and 10% coastcross hay (Cynodon spp) diet. Dried citrus pulp was added at 23.7, 46.1 and 68.4% of dry […]

It was evaluated the effects of using products containing propolis in two propolis concentrations (B and C) and two alcoholic extractions (1 and 3) and sodium monensin in forage based diet on intake, total and partial digestibility and ruminal characteristics in cattle. It was used four Holstein castrated bovines, with body weight of 221 ± 21 kg, implanted with ruminal cannulla, in a 4 × 4 Latin square experimental design. The experimental diets were composed of 72.5% roughage and 27.5% […]

The objective of this study was to evaluate the characteristics of the carcass, tissue composition in the section between 9th and 11th ribs, centesimal composition of Longissimus dorsi muscle and the proportion of the non-carcass components of non-castrated male lambs, fed in feedlot with diets containing 1.49, 1.55, 1.62 and 1.68 Mcal of net energy/kg of dry matter. Diets were composed by corn silage as the roughage and the concentrate was composed by a commercial ration and the energetic supplement […]
