PSIII-13 The Effects of Corn Gluten Feed and Corn Dried Distillers Grains as a Replacement for Soybean Meal on Boer Type Goat Diets

Abstract

Abstract The objective of this study was to evaluate the efficacy of corn dried distillers grains with solubles (DDGS) or corn gluten feed (CGF) as a replacement for soybean meal (SBM) in a Boer goat diet. A total of 75 meat goat kids (26.9 0.2 kg) were placed in 25 pens (3 kids per pen and 5 pens per treatment) for a 35-day experimental period at the Kansas State University Sheep and Meat Goat Center. Kids were allotted to one of the following isocaloric and isonitrogenous diets that varied in protein source: 1) SBM; 2) 100% DDGS/0% CGF; 3) 66% DDGS/33% CGF; 4) 33% DDGS/66% CGF; and 5) 0% DDGS/100% CGF. Diets were pelleted and supplied the sole source of nutrition. Goats and feeders were weighed weekly to determine ADG, ADFI, G:F, cost per kg of diet, and cost per kg of gain. Data were analyzed using the GLIMMIX procedure of SAS (SAS Inst., Cary, NC) with pen serving as the experimental unit. Differences were considered significant if P0.05. Treatment did not impact BW (P = 0.999), ADG (P = 0.723), ADFI (P = 0.210), or G:F (P = 0.796; Table 2). While diet cost differed due to differences in price of soybean meal and the corn co-products, there was no evidence (P = 0.941) that cost per kg of gain was less for goats fed the corn co-products. However, feed cost per goat was less (P = 0.0008) with diets containing corn co-products, regardless of level. These data allow producers to make more informed feeding decisions with a broader understanding of potential implications of corn gluten feed use in goats.
