Performance of Production and Egg Quality In Japanese Quail (Coturnix coturnix japonica) Fed Low Dietary Protein Suplemented By Commercial Enzyme

Abstract

The experiment were conducted to determine the effect of low dietary protein level suplemented by commercial enzyme on egg production performance and egg quality. The experiment used 200 Japanese female quails with the average body weight 119,39 ± 0,01 g. They kept in wire battery cage. The experiment used Completely Randomized Design with 4 treatments of ration, each consisted of 5 replications of 10 quails. The treatments consisted of four different rations for quail production period: standard ration (20 % crude protein), low protein level (18 % crude protein) and low protein level suplemented by 0,05 % commer-cial enzyme respectively. Data were analyzed by ANOVA and tested by Duncan Multiple’s range Test. The result of experiment showed that these production was significantly affected, while egg quality was not significantly influenced by commercial enzyme suplement in the ration. The experiment concluded that during production period the use of standard ration may be replaced by the use of low protein level suplement by 0.05% commercial enzyme.
