Recria de bovinos de corte em pasto durante o período seco

Abstract

The aim of this research was to evaluate the effect of dietary supplementation on cattle performance kept in pastures during the dry season. For this, two experiments were conducted. The first experiment aimed to evaluate the forage production and the efficient use of supplemental diet in beef cattle performance in the growing, in mombaça pastures during the dry season. Thirty-four non-castrated male animals were used. The animals were Caracu pure and crossed (½Senepol X ½ Caracu), were distributed according to the genetic group and body weight in eight mombaça guineagrass paddocks. The experimental design were randomized blocks, with two treatments and four replications. The animals received multiple mineral mixture (MMM) and concentrated supplement (CS), in amounts of 0.25 to 1% of body weight (BW). Providing multiple mineral mix or concentrate supplement provided an alternative use of Panicum maximum cv. Mombaça pastures during the dry season. The second experiment was conducted to evaluate forage production and performance of beef cattle in deferred pastures of B. brizantha and B. decumbens and supplemented with multiple mineral mixture, during the dry season. Twenty-eight non-castrated male were used. The Caracu animals were randomly divided into pastures of B. brizantha and B. decumbens. All animals were supplemented with multiple mineral mixture, provided the amount of 0.25% of body weight (BW). Animals in B. decumbens pastures achieved better individual performance when they received supplementation with multiple mineral mixture.
