Resumo: |
The objective of this study was to evaluate the effect of substitution of soybean meal protein by cottonseed meal protein (FA) on the performance of broiler chickens. The treatments consisted of a reference diet containing corn and soy meal and four experimental diets, substituting 10%, 20%, 30% and 40% of soybean meal crude protein of reference diet. The results obtained were analyzed through the SAS mixed procedure. The performance results had been correlatedwith the diets cost for bioeconomic analysis. The study showed that until the level of 40% of substitution did not have significant effect on the weight gain (GP) and feed intake (CR). However, linear increase in the feed conversion have occurred (CA). The rentability presented negative linear effect for diets containing cottonseed meal. The zootechnical performance of the broilers was not wronged, however the feed conversion reduced the yield of the production. |
