The intake, the apparent digestibility of nutrients and the ingestion behavior of four Holstein steers with average weight of 300 kg and 20 months of age, receiving diets containing Tifton 85 hay with different particle sizes (5, 7, 10 mm and whole) were evaluated. A 4 × 4 Latin square experimental design with four steers and four periods was used. Intakes of dry matter, organic matter, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, total carbohydrates and non-structural […]
