| The objective of this study was to evaluate the use of the dietary cation-anion balance (DCAB) on the calcium metabolism in male Nellore steers with a mean age of 10 months. Three experimental diets were tested: a cationic diet, a diet consisting of Tifton hay only, and an anionic diet with +15.2, +23.9 and −10.0 mEq/100 g DM of DCAB values in the diet. The anionic diet was calculated as the addition of salts of ammonium chloride and magnesium sulfate. Based on the isotope dilution technique, the negative DCAB value used in this study (−10.0 mEq/100 g DM) does not affect calcium metabolism, especially endogenous losses and true absorption. |

| The objective of this experiment was to estimate the curve of dehydration, chemical composition and in vitro dry matter digestibility (IVDMD) and crude protein digestibility (IVCPD) of tifton 85 hay, produced single or overseeded with ryegrass or white oat IPR 126. The experimental design was in randomized blocks, in a 3 × 10 factorial arrangement, with three cropping systems and ten evaluation times (0, 4, 8, 24, 28, 32, 48, 52 and 56 and 71 hours after harvest) during the dehydration process. For chemical composition and in vitro DM and CP digestibility, the experimental design was in randomized blocks with three cropping systems and three evaluation times (before cutting, before baling and 100 days after of storage). It was found that tifton 85... |

| Com o objetivo de avaliar o efeito do uso de probiótico (Saccharomyces cerevisiae) em dietas para cavalos, utilizaram-se quatro equinos machos com média de 400 kg de peso corporal, em delineamento em quadrado latino 4 õ 4. As dietas foram compostas de concentrado e feno de capim-tifton 85 (de baixa qualidade) ou feno de alfafa (de alta qualidade), com ou sem a adição de levedura. Cada período experimental teve duração de 36 dias, com coleta total de fezes, para determinação dos coeficientes de digestibilidade aparente dos nutrientes, e coleta de fezes, para determinação do pH e da microbiologia fecal. A utilização de probiótico não alterou os coeficientes de digestibilidade aparente dos nutrientes das dietas, com exceção do extrato etéreo. A qualidade... |
