Protein sources in multiple supplements for finishing crossbred steers on Brachiaria pasture, in the wet season: productive and economical performance. Rev. Bras. Zootec., 38 (8): 1553-1560

The performance of Holstein-Friesian * zebu crossbred beef steers supplemented with different protein sources on Urochloa brizantha cv. Marandu pasture during the wet season was evaluated. The area was divided into paddocks of 1.5 ha, with an availability of dry matter and potentially digestible dry matter of 7.46 and 4.50 tonnes/ha, respectively. 25 animals with 229 kg initial weight and 12 months of age were distributed in a completely randomized design, with 5 treatments and 5 replications. The following treatments were evaluated: mineral mix (MM) control group, soyabean meal (SM) + cottonseed meal (CM) and MM, SM and MM; ground soyabean grain (GGS) and MM, whole soyabean grain (WSG) and MM supplied daily on the amount of 60, 510, 460, 560 and 560 g/animal, respectively. Even without statistical significance, the animals that received the supplement showed a gain of 211 g (23.78%) greater than the animals that received only mineral mix. The use of multiple supplements based on soyabean meal and cottonseed meal provided 247 g/animal/day greater than the mineral mix. The supplementation with protein sources may provide additional gain during the wet season. Multiple supplementation provided economic returns, regardless of the protein source evaluated in relation to the control group.
