Nine ruminally fistulated Nellore steers were located in nine paddocks of palisade grass (Brachiaria brizantha cv. Marandu) pasture under daily supplementation (seven times per week), from Monday to Friday (five times per week) or Monday, Wednesday and Friday (three times per week). Ruminal fluid was sampled on two consecutive days. On the first day, all the animals that were supplemented (D1) and other subsequent day in which only for the animals under daily supplementation received the supplement (D2). The supplementation […]

The objective of this trial was to evaluate quantitative and qualitative traits of carcass and meat from grazing steers submitted to one of the following three supplementation strategies: daily supplementation (DS), alternate days supplementation (AS) or Monday to Friday supplementation (MFS). Twenty-four crossbred steers (Bos indicus x Bos taurus) averaging 230 kg of initial body were used in a completely randomized block design (three treatments and eight replicates/treatment). Animals were maintained in pasture of Brachiaria brizantha cv. Marandu from the […]
