Abstract:

Abstract: In this study, 400 commercial Cherry Valley ducklings were selected and fed with daily forage containing different proportions Potamoget Pectinatus L. until 42 daily ages. By analyzing the nutritional ingredient of grass powder in Bulong Lake and feeding the duck, the role of this grass powder in the duck slaughter performance was researched. The result showed that the daily forage containing 4% grass powder can increase the food consumption and decrease the feed/gain rate. Comparing to the lower slaughter performance, the cultivate benefit was improved. So this method has a better prospect of promotion and application.
