It was evaluated grazing times of heifers in natural pasture, obtained by visual assessment in 5-minute intervals. By using the original data, it was calculated observation intervals of 10, 15 and 20 minutes. It was used four crossbreed Angus × Nellore heifers, with average weight of 249 ± 6 kg BW. The completely randomized block design was used with four treatments (forage allowance of 4, 8, 12 and 16 kg DM/100 kg BW) and two replicates, and type of soil […]
