摘要/Abstract

摘要： 该试验旨在研究樱桃谷成年公鸭对福建、山东、广东三种产地水解羽毛粉的养分消化情况及氨基酸利用率。选择48只健康成年樱桃谷公鸭，随机分为4组，每组12只，分别饲喂100%玉米淀粉（对照组）和85%玉米淀粉+15%水解羽毛粉（产地为福建、山东、广东）。通过强饲??全收粪法代谢试验，收集排泄物，测定饲料和排泄物的重量和水分、干物质、粗蛋白质、氨基酸、钙、磷含量。不同产地水解羽毛粉在干物质、粗蛋白和氨基酸含量方面存在差异。福建水解羽毛粉干物质含量最高（93.7%），粗蛋白质为83.4%。山东和广东水解羽毛粉粗蛋白稍高，但差异不显著（P>0.05）。氨基酸利用率方面，福建水解羽毛粉的天冬氨酸、苏氨酸和谷氨酸等氨基酸真可利用率显著高于山东和广东（P<0.01）。强饲不同产地水解羽毛粉后，试鸭粪便的重量和干物质、粗蛋白质、钙、磷含量无显著差异（P>0.05）。不同产地水解羽毛粉饲喂的樱桃谷肉鸭粪中，干物质、蛋白质和氮的消化率在福建、山东和广东之间未表现出显著差异（P>0.05）。不同产地水解羽毛粉除氨基酸以外的其他营养成分差异较小，福建水解羽毛粉的氨基酸含量较高，尤其是天冬氨酸和苏氨酸真可利用率显著优于山东和广东水解羽毛粉。樱桃谷公鸭对福建、山东、广东水解羽毛粉干物质和粗蛋白质消化率相差较小。

Abstract: This study aimed to evaluate the nutrient digestibility and amino acid utilization of hydrolyzed feather meal produced in Fujian，Shandong，and Guangdong provinces in male Cherry Valley ducks at sexual maturity. Forty􀆼 eight healthy adult male Cherry Valley ducks were randomly divided into four groups with 12 ducks in each group. They were fed with 100% corn starch（control group）and 85% corn starch + 15% hydrolyzed feather meal（Fujian， Shandong，and Guangdong），respectively. Through the metabolic trial of forced feeding􀆼total feces collection，the excreta were collected，and the quality，moisture，dry matter，crude protein，amino acids，calcium and phosphorus of feed and excreta were determined. There were differences in the contents of dry matter，crude protein and true amino acids in hydrolyzed feather meal originating from different regions. The hydrolyzed feather meal produced in Fujian showed the highest contents of dry matter（93.7%） and crude protein（83.4%）. The crude protein contents of hydrolyzed feather meal produced in Shandong and Guangdong were slightly higher than those of Fujian，but the differences in crude protein were not significant（P>0.05）. The true amino acid availability of aspartic acid，threonine and glutamic acid in Fujian hydrolyzed feather meal was higher than that in Shandong and Guangdong（P<0.01）. After force- feeding the diets containing hydrolyzed feather meal produced in Fujian，Shandong and Guangdong，no differences was observed in the weights of feces and fecal contents of dry matter，crude protein，calcium，and phosphorus. The digestibility of dry matter，protein and nitrogen in the feces of Cherry Valley ducks fed hydrolyzed feather meal from different production areas did not show significant differences among Fujian，Shandong and Guangdong（P>0.05）. There were few differences in other nutrients except amino acids in hydrolyzed feather meal from different production areas. The amino acid contents of hydrolyzed feather meal in Fujian were higher，especially the true availabilities of aspartic acid and threonine was significantly better than those of hydrolyzed feather powder in Shandong and Guangdong. The digestibility of dry matter and crude protein of hydrolyzed feather meal among Fujian， Shandong，and Guangdong was less significant.

Key words: Hydrolyzed feather meal, Cherry valley duck, Nutrient digestibility, True amino acid availability
