| Objetivou-se avaliar níveis de concentrado para bezerros em crescimento. Foram utilizados quatro bezerros mestiços, Holandês × Zebu, com idade média de 7 meses e 155 kg de peso vivo, distribuídos em quadrado latino (4×4). Os animais foram alimentados à vontade, na forma de dieta completa contendo os níveis de 20, 40, 60 e 80% de concentrado, com base na matéria seca (MS). As dietas foram compostas de feno de Cynodon dactylon, fubá de milho, farelo de soja e mistura mineral e foram isoprotéicas (15,4%). Os consumos de MS, matéria orgânica (MO), fibra em detergente neutro (FDN) e carboidratos totais (CT) apresentaram comportamento linear e os consumos de proteína bruta (PB) e nutrientes digestíveis totais (NDT), comportamento quadrático, em kg/dia.

| ABSTRACT The objective of this study was to evaluate the effects of different lipid sources in diets for lactating cows on milk yield and composition, conjugated linoleic acid (CLA) content, and fatty acid profile in the milk fat. Five primiparous Holstein cows were distributed in a 5 × 5 Latin square design. Treatments were: control (no lipid addition) and four other diets containing different lipids sources - ground raw soybean, cottonseed, soybean oil, and calcium salts of soybean fatty acids (CSSFA). The greater milk yield (kg/day) and milk lactose (g/kg) and solids non-fat (g/kg) contents were obtained with the animals fed diets with CSSFA. Regarding the fatty acid profile in the milk fat, the diets with CSSFA and ground raw soybeans produced the... |

| This study evaluated the effects of organic and inorganic sources of minerals in diets for mid-lactation dairy cows on milk yield and composition, intake and total apparent digestibility of dry matter and nutrients, blood parameters, microbial protein synthesis, and energy and protein balances. Twenty Holstein cows averaging 146.83±67.34 days in milk and weighing 625.30±80.37 kg were used. The experimental design was a crossover. Diets were composed of corn silage (50%), ground grain corn, and soybean meal, differing with regard to the sources of trace minerals, plus an organic and inorganic mix. The organic mineral source increased milk fat and fat-corrected milk yield without changing milk yield, intake, or total apparent digestibility. Blood parameters,... |

| This study aimed to evaluate the effect of intraruminal infusion of propionic acid (RPA) associated to two (80:20 and 60:40) forage:concentrate ratios (FCR), for young bulls. Four Holstein × Zebu crossbred young bulls with average age of 7 months and 160 kg of body weight (BW) were distributed to a 4 × 4 Latin square design. A total mixed ration, isonitrogenous diets, was ad libitum fed to animals. The propionic acid was obtained by fermentation of reconstituted milk whey by the consortium of bacteria Enterococcus sp. and Veillonella sp.. Daily and along with the supply of solid feeds, 2 L of the compound containing propionic acid were intrainfused in the rumen. There was no RPA × FCR interaction for the intake of nutrients, except for total digestible... |
