摘要/Abstract

摘要：

为了探究填饲应激对北京鸭生产性能、腿部肌肉品质、血清激素和血气指标的影响，本试验选择160只39日龄、平均体重为(2.573±0.096)kg的北京鸭，分为2组，每组80只，分别为基础日粮填饲组和基础日粮对照组。试验6 d后，各处理组随机选取8只肉鸭分别称取体重，计算平均日增重，并进行腿部肌肉品质（pH、滴水损失率）、血清激素（ACTH、CORT、T3、T4）和血气检测。结果表明，填饲组肉鸭填饲后体重和平均日增重均显著高于对照组（P<0.05）；血清CORT、AnGap、Hct和Hb含量极显著高于对照组（P<0.01）；而填饲组45 min和24 h时的胫骨前肌pH极显著低于对照组（P<0.01）。结果显示，填饲能显著提高肉鸭的增重效率；但同时会显著降低肉鸭腿部肌肉的肉品质；填饲会使肉鸭血清中CORT的含量显著升高，使其出现应激征象；填饲还会在一定程度上影响肉鸭的血液循环系统。

Abstract:

The objective of this study was to evaluate effects of force-feeding stress on growth performance，meat characteristics of legs，serum hormone and blood gas parameters of Peking ducks.A total of 160 thirty-nine-day-old Peking ducks with average body weight (2.573±0.096) kg were randomly divided into 2 groups （force-feeding group and control group） with 80 ducks per treatment.After 6 days，8 ducks from each treatment were selected randomly to be weighted for calculating average body weight and average daily gain，and meat characteristics of leg(pH and drip loss rate)，serum hormone (ACTH，CORT，T3 and T4) and blood gas parameters were tested.The results showed that the average body weight and average daily gain in force-feeding group was significantly higher than those in control group (P<0.05).And the CORT，AnGap，Hct and Hb in force-feeding group was significantly higher than that in control group (P<0.01).The pH at 45 min and 24 h of tibialis anterior in force-feeding group were significantly lower than those in control group (P<0.01).It was concluded that force-feeding could enhance gaining weight significantly.However，force-feeding could affect the meat characteristics of leg significantly and induce physiological stress of Peking ducks by increasing serum CORT.At last，force-feeding could also influence the blood circulation system of Peking ducks.
