Employment of steep liquor and corn germ meal on broiler diets
Keywords:

Abstract
The objective of the study was to evaluate in broiler diets, the feeding value of corn germ meal (CGM) mixture at 50% and the addition of 50% corn liquor (CL) without and with carbohydrase enzymes (CH) and fermentation for 24 hours. A trial with CL + enzymes for non-starch polysaccharides (NSP) and CL with fermentation for 24 h was carried out. A total of 240 male Ross 708 broilers were used, from 6 to 50 days of age fed corn + soybean paste based diets (starter, grower and finisher), with 5, 10 and 20 % CGM, with the inclusion of different presentations of CL (0 % CL, natural CL and fermented CL) in percentages equal to those of CGM without and with carbohydrase enzymes (103 000 U/g of xylanases, 128 000 U/g of cellulases and 33 000 U/g of beta-glucanases) at 25 ppm. Weight gain of 6- to 50-day-old chicks improved 5 % (P<0.05) with the addition of natural CL to CGM. The combination of CGM + natural CL increased feed value in broiler diets. The addition of enzymes in diets with CGM + natural CL did not affect broiler performance.
