El empleo de licor y harina de germen de maíz en dietas para pollos de engorda

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.
