Effect of Protein Levels in Fermented Complete Feed on Growth Performance and Carcass Characteristic in Barbary Duck

Abstract

The objectives of this study were to determine the effect of protein levels in fermented complete feed on growth performance and carcass characteristic in Barbary duck. Seventy two Barbary duck, 4 weeks of age were divided into 3 groups 4 replications in each group and 6 ducks in replication. Completely Random Design was used in statistical analysis in this experiment. The dietary treatments were 1) fermented complete feed 12% of crude protein (CP), 2) fermented complete feed 16% of CP and 3) fermented complete feed 20% CP. The results were showed that dry matter feed intake and average daily gain were significantly different among treatment (P<0.05). Duck fed with 16% CP and 20% CP diet were not different in dry matter intake and average daily gain, but higher than duck fed with 12%CP diet. Feed conversion ratio and carcasscharacteristics were not significantly different among treatments. Fermented complete feed 16% CP was more suitable for Barbary duck production in order, and it was lower cost when compared to 20% CP.
