Effects Of Rapeseed Meal,Cottonseed Meal And Corn Germ Feed On The Cherry Valley Ducks

A study was conducted to determine the effects of rapeseed meal,cottonseed meal and corn germ levels on ducks.Used 2 weeks cherry valley ducks,study included feeding and metabolism experiments for a 3-weeks trial. Ducks were allocated to 10 dietary treatments arranged as a 3×4 factorial design. The basal diet was corn-soybean. Treatments diets consisted of 14%,11% or 8% rapeseed meal 9%,6% or 3% cottonseed meal and 11%, 8% or 5% corn germ. The production performance,slaughter performance,nutrient retention,meat nutrients and blood biochemical indicator were determined.The main results were showed as follows:1.The production performance:Results of 3 weeks feeding experiment were as follows:The average body weight of groupⅠ,Ⅱ,Ⅲincreased of 12.72%(P﹤0.01),10.16%(P﹤0.05),8.36%(P﹤0.05),it had obviously effect on the average daily feed corn-sorbean,but the rest groups had no obviously effect on the average daily feed corn-sorbean durings 21 to 28 days.During the period of 28～35days old,the average body weight of groupⅡ,Ⅴ,Ⅵgroups significantly improved by 25.83%(P﹤0.01),25.24%(P﹤0.01),7.70%(P﹤0.05)percentage points respectively.Except for the ninth...
