Evaluation of Crude Enzyme Addition Based Muscovy Duck Feed on Reproduction Perfomance

The purpose of this was to evaluate the reproductive perfomance of muscovy duck by using crude enzymes as additive in basal feed. The research material’s 32 muscovy duck, 4 males,  28 females, aged 5 months and normal body weight of males muscovy duck 3,5 – 4 kg dan females 2 – 2,5 kg. The feed material used was basal feed with the addition crude enzymes in each treatment. The cage equipment used were feed, water cup, hatching machine and scales. The research was conducted for 40 days with experimental methods and Cross Over Design (Switching Design) observation period of four times, seven days with treatment, three days of break and start again next period.  The addition of crude enzymes in muscovy duck feed can improve reproductive perfomance. The results showed that the use of 0.2% crude enzymes (T2) in basal feed can increase the hatching weight of day old duck and dod survival without mortality. The other results, increased hatchability occurred in the basal feed containing 0.1% crude enzymes (T1), compared to the control feed without the addition of crude enzymes. This means that using of 0.2% crude enzymes in feed as an additive increased hatching weight, dod survival and muscovy duck hatchability.
