饲养方式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
Effects of rearing systems on growth, slaughter performance, meat quality and serum biochemical parameters of White-feather muscovy duck
摘要
Abstract
This study was conducted to investigate the effects of rearing systems on growth performance,carcass traits,meat quality and serum biochemical parameters of White-feather muscovy duck.180 male and 180 female 22-dayold White-feather muscovy ducks were divided and raised in separate pens according to sex and housing system,with 3 replicate pens of 30 male or 30 female ducks per pen for each rearing system.The rearing system consisted of floor rearing system (with outdoor playground) and net rearing system.The experiment lasted for 63 days.The results showed that:① Compared with the floor-rearing system,the average daily gain,average daily feed intake,breast muscle L*,b* and drip loss,and serum glucose,total cholesterol and low density lipoprotein cholesterol contents of White-feather muscovy ducks were significantly increased by net-rearing system (P＜0.05),while slaughter rate,breast muscle rate,and serum albumin and high density lipoprotein cholesterol contents of White-feather muscovy ducks were significantly decreased by net-rearing system (P＜0.05).② The average daily gain,average daily feed intake,slaughter rate,eviscerated carcass percentage,leg muscle rate,and breast muscle L* and drip loss of male White-feather muscovy ducks were significantly higher than those of female ducks (P＜0.05),while F/G,abdominal fat rate and intramuscular fat of male White-feather muscovy ducks were significantly lower than those of female ducks (P＜0.05).③ Significant interaction between rearing systems and sex were observed in average daily gain,F/G,breast muscle rate and serum glucose content.In conclusion,net-rearing system was beneficial to the gowth performance of White-feather muscovy duck,but it had negative influences on carcass traits and meat quality.The growth performance and carcass traits of the male White-feather muscovy ducks were better,while the female White-feather muscovy duck exhibited higher meat quality.There was only a significant interaction effect between rearing system and sex on ADG,F/G,breast muscle rate and serum glucose content.关键词
