Whole Soyabeans, a Protein Supplement for Protein Supplement in Pig Rations.

Abstract

Two experiments are reported using a total of 46 pigs. In the first , raw or cooked soyabeans were fed with raw sweet potato to growing pigs and compared to a sorghum-based control ration. Performance on the control ration was superior to that on either of the soyabean rations. Cooking of soyabeans markedly improved performance. In the second experiment cooked soyabeans and cooked sweet potato were fed, either unsupplemented or supplemented, with salt or salt and bone ash and compared with a sorghum-based control ration. The pigs fed the control ration again showed superior performance. The addition of salt but not bone ash markedly improved performance over that of the unsupplemented group.
