Effect of dietary enzyme levels on growth performance of French Muscovy ducks raised on slatted floors
This study was conducted to evaluate the effects of dietary enzyme supplementation on the growth performance and feed utilization efficiency of French Muscovy ducks (4-10 weeks old) raised on slatted floors. A total of 144 French Muscovy ducks at four weeks old were allotted in a completely randomized design of four treatments, three replicates, consisting of diets supplemented with 0% (control), 0.1%, 0.2%, and 0.3% enzyme. The results indicated that the Muscovy ducks fed the diet with 0.3% enzyme supplementation achieved the highest 10-week body weight (2358.90 g/bird) and overall average daily gain (38.16 g/bird/day). The FCR was lowest in the 0.3% enzyme treatment (2.77). Furthermore, the amount of residual nutrients content in their feces from the 0.3% enzyme treatment group was the lowest (p < 0.05). In conclusion, supplementing the feed of Muscovy ducks with 0.3% enzyme significantly improves weight gain and nutrient digestibility.
