摘要
Abstract
This study aimed to explore the comprehensive effects of adding different proportions of glutamic acid residue to diets on the growth performance,slaughter performance and economic benefits of Z-type Beijing ducks.A total of 800 healthy one-day-old Z-type Beijing ducks of uniform weight were selected and randomly divided into four groups based on similar body weight,with eight replicates per group and 25 ducks per replicate.The control group was fed the basic diet,while three experimental groups received diets supplemented with 2%,4%and 6%glutamic acid residue,respectively.Results showed:1)There were no significant differences among groups in weight at 35 days,average daily feed intake,average daily gain and feed-to-meat ratio;2)The 4%supplementation group had a significantly higher skin fat rate than the control group(P<0.05),while chest muscle rate,leg muscle rate,abdominal fat rate,and gizzard rate showed no significant differences among groups;3)Economic benefit analysis indicated that the 6%supplementation group achieved the highest profit per duck.However,considering overall growth stability,feed intake performance and slaughter quality,a 4%glutamic acid residue addition can balance normal feed intake and eco-nomic benefits,showing greater potential for large-scale promotion.关键词
