Effect of different supplement levels of soybean pomace in the basal mixed feed diet on the growth performance of Muscovy ducks (Cairina moschata)
An experiment was conducted on 72 healthy Muscovy ducks, starting at 28 days of age, to evaluate the effect of different soybean pomace supplementation levels in the basic mixed feed on the growth performance of Muscovy ducks (Cairina moschata). The experiment was arranged in a Completely Randomized Design (CRD) with 3 treatments and 3 replications. Each experimental unit consisted of 8 Muscovy ducks, with four of male and four of female were randomly selected. The three treatments were designed with 3 soybean pomace supplement levels of 0, 15 and 30% in the basic mixed. Treatment 0 (TM0) consisted of 100% mixed feed only, Treatment 1 (TM1) included 15% soybean pomace and 85% mixed feed, and Treatment 2 (TM2) contained 30% soybean pomace and 70% mixed feed. The results of the weight gain of Muscovy ducks from 5 to 12 weeks showed that Treatment 1 had the significantly higher weight gain (36.40g/duck/day) (P≤0.05), than those of Treatment 2 (33.89g/duck/day) and Treatment 0 (32.78g/duck/day). The feed conversion ratio (FCR) was the lowest in Treatment 1 (3.89), followed by Treatment 2 (4.15), and highest in Treatment 0 (4.41), with (P≤0.05). Among the three treatments, the treatment 1 included 15% soybean pomace combined with 85% mixed feed had higher weight gain and better feed conversion ratio as compared to those of the two other treatments. It was concluded that at 15% soybean pomace supplement in basic mixed feed diet gave the higher growth performance and better feed conversion ratio of Muscovy ducks.
