Two experiments were carried out with the objective of evaluating the effects of the frequency of supplementation with two proteins sources on productive and economical performance (experiment 1) and the nutrients digestibility of steers in supplemented pasture during the dry season over a year. It was used twenty weaned zebu calves at the age of 10 months and initial live weight (LW) of 208.43 kg, distributed in four paddocks of Brachiaria brizantha cv. Marandu, each one with 1.6 ha. Both […]

The objective of this study was to evaluate weight gain of beef steers grazing Brachiaria brizantha cv. Marandu and receiving one out of three different supplementation strategies during the rainy season of 2003 and the dry and rainy seasons of 2004. Twenty-four crossbreed steers averaging 230 kg of initial body weight were assigned to one of the following supplementation strategies: daily supplementation (DS), supplementation in alternated days (AD), or supplementation from Monday to Friday (MF) in a completely randomized design […]
