摘要
选择健康的樱桃谷商品雏鸭400只,以含不同比例龙须眼子菜的日粮饲养至42日龄。通过对以龙须眼子菜为优势种的布龙湖草粉的营养成分分析和肉鸭的饲养试验来研究该草粉在肉鸭屠宰性能方面的作用。试验结果表明:添加4%的草粉可以增加采食量,降低料肉比,虽然屠宰性能有所下降,但是能增加养殖效益,具有很好的推广和应用前景。
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.
