【摘要】：试验研究氧化三甲胺(TMAO)对肉鸡屠宰性能和肉质的影响。选取150只1日龄爱拨益家(AA)肉仔鸡,随机分成3个处理组,每处理组设2个重复,每重复25只,分别向基础日粮中添加0、100和150 mg/kg的TMAO。在21和42日龄时每重复随机抽取3只空腹超过12 h的肉鸡,进行屠宰性能和肉品质的测定。结果表明,肉鸡日粮添加TMAO后肉鸡屠宰率提高1.56%(P=0.043)、半净膛率提高7.47%(P=0.001)、全净膛率提高6.11%(P=0.059)、腿肌率提高18.46%(P=0.032)和腹脂率降低21.66%(P=0.036)。150 mg/kg组胸肌蒸煮损失率线性降低45.37%(P=0.017),100 mg/kg组胸肌红度增加104.28%(P=0.005),150 mg/kg组腿肌亮度线性降低12.80%(P0.001)。结果表明,日粮中添加TMAO能够提高肉鸡屠宰性能,改善鸡肉品质,添加150 mg/kg效果较佳。
[Abstract]:The effects of trimethylamine oxide (TMAO) on slaughter performance and meat quality of broilers were studied. One hundred and fifty 1-day-old Epokea (AA) broilers were randomly divided into 3 treatment groups, with 2 replicates and 25 replicates in each treatment group. TMAO of 0100 and 150 mg/kg was added to the basal diet, respectively. At 21 and 42 days of age, 3 broilers with fasting for more than 12 hours were randomly selected for slaughter performance and meat quality. The results show that After adding TMAO to the diet, the slaughter rate of broilers increased by 1.56% (P0. 043), the half bore rate increased by 7. 47% (P0. 001), the rate of full yield increased by 6. 11% (P0. 059), the rate of leg muscle increased by 18. 46% (P0. 032) and the rate of abdominal fat decreased by 21. 66% (P0. 036). 150 mg/kg group showed a linear decrease of pectoralis muscle loss rate by 45. 37% (P0. 017). The pectoral muscle redness increased by 104.28% (P0. 005) in 100 mg/kg group. The leg muscle brightness of 150 mg/kg group decreased linearly by 12. 80% (P0. 001). The results showed that the addition of TMAO to the diet could improve the slaughtering performance of broilers, improve the quality of chicken, and the effect of adding 150 mg/kg was better.
