Supplementation Spent Grain from Waste Brewery in the Diet of Household Ovine System in the State of Mexico

Peña, B.S and Posadas M.E

Industrial wastes poses a threat of environmental pollution worldwide, due to high biochemical oxygen demand for destruction. The beer industrial process, produces large amounts of semi-liquid waste as by-products, which can be reused in animal feed with beneficial results over performance in ruminant animals. In Mexico, the ovine household production system is based on forages in state of Mexico with low efficiency, principally during dry seasons in the year. The aim of this study was to use spent grain to supplement the ration of landrace hampshire sheep into a household system production. The study was conducted in the municipality of Cuautlalpan, State of Mexico. Nine sheep landrace (7 females and 2 males) with an initial weight between 35 ± 10 kg were used and grouped into two treatments. The control group (T0) without supplementation, T1 supplementation with 10% of two spent grain and T2 with 10% of six spent grain, in a statistical model completely randomized. The one way analysis of variance (ANOVA) of weight gain was run in a general linear model procedure (GLM) of SAS, 2009. The results showed a positive effect of 10% supplementation with spent grain in the diet of crossbred sheep in on the daily weight gain (P ≤ 0.05), versus non untreated group. It is concluded that supplementation with spent grain from six malts in a 10% of dry basis ration, helps improve weight gain on landrace sheep in household system production.
