Productive efficiency of buffalos in the State of Pará in different conditions of mineral supplementation

Abstract

The monitoration of the consumption of different minerals mixtures was evaluated in 84 crossbred buffaloes distributed in two farms (1 and 2) located in Meso-area of Paraense's Northeast for the evaluation of the cost benefit of each product. The farms presented pastures of the type Brachiaria brizantha, cv. Marandú where the animals were maintained for 14 months. The animals were divided in two lots. The lot 1 of each farm received a commercial product of mineral supplementation recommended for buffalos (Topbúfalo Matsuda®) and the lot 2, the commercial product of conventional mineral supplementation of the property, in which was indicated for the bovine species. In Finance 1, the consumption of the mineral mixture to be tested was inferior to the consumption of the conventional mineral mixture and in Finance 2, the consumption of both lots was similar. The commercial product recommended for buffalos in pasture regime, in both systems, it promoted a better acting in the earnings of weight of the buffalos when compared to commercial products recommended for the bovine species. The medium weight of the hot carcass of the animals that consumed the mineral mixture to be tested was superior the one of the animals that received the conventional mineral mixture. The expense with the mineral supplementation was superior with the conventional products in both farms, with smaller net yields than the supplementation to be tested. Was ended that the productive efficiency of the animals using a recommended supplementation for buffalos in pasture regime overcomes the productive efficiency of buffalos when a supplementation is used recommended for bovine.
