【摘要】：为探究不同饲养方式和性别对白羽番鸭生长性能、屠宰性能、肉品质及血清生化指标的影响,选取22日龄公、母白羽番鸭各180羽,两性别均随机分为2组,每组3个重复,每个重复30羽。2种饲养方式分别为地面平养(带户外运动场)和网上平养,试验期为63d。结果表明:(1)与地面平养相比,网上平养显著提高番鸭平均日增重和平均日采食量,胸肌亮度L*、黄度b*和滴水损失,以及血清葡萄糖、总胆固醇和低密度脂蛋白胆固醇含量,但显著降低屠宰率、胸肌率及血清白蛋白和高密度脂蛋白胆固醇含量。(2)公番鸭平均日增重、平均日采食量、屠宰率、全净膛率、腿肌率、胸肌亮度L*及滴水损失显著高于母番鸭,而料重比、腹脂率和肌内脂肪含量显著低于母番鸭。(3)性别和饲养方式的交互效应显著影响平均日增重、料重比、胸肌率及血清葡萄糖含量。由此可见,网上平养较地面平养能提高白羽番鸭的生长性能,但对屠宰性能和肉品质具有负面影响;公番鸭生长性能和屠宰性能优于母番鸭,而母番鸭肉品质优于公番鸭;饲养方式和性别的交互效应仅对平均日增重、料重比、胸肌率和血清葡萄糖含量有显著影响。
[Abstract]:In order to investigate the effects of different feeding methods and sex on the growth performance, slaughter performance, meat quality and serum biochemical indexes of white muscovy ducks, 180 male and 180 female muscovy ducks of 22 days old were randomly divided into 2 groups with 3 replicates in each group. The experiment period was 63 days. The two feeding methods were ground level (with outdoor sports ground) and online culture. The results were as follows: (1) compared with ground culture, the average daily gain and average daily intake of muscovy ducks were significantly increased by net feeding, and the contents of serum glucose, total cholesterol and low density lipoprotein cholesterol (LDL-C) were significantly increased by the loss of breast muscle brightness, yellow b * and dripping water, and the contents of serum glucose, total cholesterol and low density lipoprotein cholesterol (LDL-C). However, the slaughter rate, breast muscle rate, serum albumin and high density lipoprotein cholesterol content were significantly decreased. (2) the average daily gain, average daily intake, slaughter rate, full bore rate, leg muscle rate of male muscovy ducks were increased. The L* and drip loss of breast muscle brightness were significantly higher than that of female muscovy ducks, but the ratio of feed to weight, abdominal fat rate and intramuscular fat content were significantly lower than those of female muscovy ducks. (3) the interaction effects of sex and feeding style significantly affected the average daily gain and feed weight ratio. Pectoralis rate and serum glucose content. It can be seen that the growth performance of white muscovy duck can be improved on the net, but it has a negative effect on slaughtering performance and meat quality, the growth performance and slaughter performance of male muscovy duck is better than that of female muscovy duck, and the quality of female muscovy duck is better than that of male muscovy duck. The interaction between feeding style and sex had only significant effects on average daily gain, feed weight ratio, breast muscle rate and serum glucose content.
