We investigated whether corn distiller's dried grains with solubles (DDGS) or corn gluten feed (CGF) can be utilized as a lower cost replacement for soybean meal (SBM) in Boer-type grower rations. In our experiment, 75 Boer-type goats (26.9 0.2 kg, approx. 70 d of age) were used in a completely randomized design for 35 d. Goats were assigned to pens based on weight and then pens were randomly assigned to one of 5 experimental diets: 1) 100% SBM, 2) 100% DDGS, 3) 66% DDGS/33% CGF, 4) 33%DDGS/66% CGF and 5) 100% CGF. Pens consisted of 3 goats per pen with 5 pens per treatment. Each wk BW, ADG, ADFI and G:F were measured. Data was analyzed using the GLIMMIX procedure in SAS (v. 9.4, Cary, NC) with pen as the experimental unit and a designate alpha value of 0.05. Our results showed no treatment effect of diet for variables (P<0.05), except for feed cost, measured in dollars/goat for 42 d (P=0.0008). Feed cost ($/goat) was averaged $1.43 less for goats fed CGF or DDGS compared to those fed SBM (P<0.05). Treatments including DDGS or CGF showed a significant (P<0.05) quadratic effect for ADFI, g/d (P=0.038) indicating a feed intake reduction for utilization of both alternative protein sources: 66%DDGS/33%CGF, 33%DDGS/66%CGF, 100% DDDGS, 100% CGF(1,022, 1,074, 1,110 and 1140 respectively.) Therefore, our research shows that DDGS can be effectively utilized with CGF as a lower cost rumen undegradable protein replacement for SBM while maintaining BW, ADG, ADFI, and G:F metrics.en-USThis Item is protected by copyright and/or related rights.
