El uso de granos secos de destilería con solubles (DDGS) en dietas sorgo-soya para pollos de engorda y gallinas de postura

Abstract

In order to study the productive performance in broilers and hens fed DDGS, two experiments were conducted: In Exp 1, 704 Ross chicks were used from 1 to 49 d of age, divided in four treatments with eight replicates of 22 birds each one, in a completely randomized design. The treatments were: T1) sorghum-soybean meal basal diet, T2) as 1 +7% DDGS, T3) as 1 +14% DDGS, 4) as 1 +21% DDGS. In Exp 2, 288 hens Bovans White 35 wk of age were used, kept in cages for 56 d of experimentation. A completely randomized design with four treatments and three replicates of 12 hens each one was used. The treatments were: 1) sorghumsoybean meal basal diet, 2) as 1 +3% DDGS, 3) as 1 +6% DDGS, 4) as 1 +9% DDGS. The results in Exp 1, indicated (P>0.05) than the addition of 7 % of GSDS, did not affect performance and carcass yield. The results in Exp 2 showed that the use of 3, 6 and 9 % of DDGS (P>0.05) did not affect performance. There was a beneficial effect (P>0.05) in the pigmentation of egg yolk, being higher in DDGS treatments. With the results obtained in this study, we conclude that the addition of DDGS in sorghum-soybean meal diets until 7 % in broilers and 9 % in laying hens is an alternative source of protein and energy.
