摘　　要：为研究“2+3”生产模式下,日粮中添加发酵饲料对乳鸽屠宰性能、内脏器官发育及肌肉品质的影响,试验选取健康、平均体重约560 g和产蛋性能相近且同期产蛋的8月龄父母代卡奴种鸽60对,随机分为对照组(C组)和试验组(F组),每组5个重复(6对种鸽/重复)。C组和F组分别饲喂日粮+常规肉鸽保健砂和日粮+发酵饲料与常规肉鸽保健砂混合(1:1)的饲粮,试验周期50 d(其中预饲期7 d,试验期43 d)。结果显示:日粮中添加发酵饲料可显著提高乳鸽活体重、屠体重、屠宰率、半净膛重、半净膛率、全净膛重(P<0.01)以及胸肌重(P<0.05);F组乳鸽腺胃重、腺胃指数、肝脏重、肝脏指数、肺重、肺指数、肾脏重(P<0.01)以及脾脏重(P<0.05)均显著高于C组;饲喂发酵饲料可显著降低乳鸽胸肌肉电导率(P<0.01),提高胸肌肉L*值(P<0.01)和胸肌氨基酸成分(P<0.05)。结果表明日粮中添加发酵饲料对乳鸽屠宰性能、内脏器官发育和肉品质等方面均有显著提高,可为肉鸽养殖户提供参考和借鉴。This experiment was conducted to study the effects of fermented feed on slaughter performance,visceral organ development and muscle quality of squabs under'2+3'production mode.A total of 60 healthy 8-month-old Karnau breeders with similar average body weight(about 560 g)and laying performance were randomly divided into control group(group C)and experimental group(group F),with 5 replicates in each group(6 pairs of breeders/replicate).Group C and group F were fed the diets of diet+conventional meat pigeon health sand and diet+fermented feed mixed with conventional meat pigeon health sand(1:1),respectively.The experimental period was 50 days(including 7 days of pre-feeding period and 43 days of experimental period).The results showed that the addition of fermented feed to the diet significantly increased the live weight,slaughter weight,slaughter rate,semi-eviscerated weight,semi-eviscerated rate,total eviscerated weight(P<0.01)and breast muscle weight(P<0.05)of squabs.The glandular stomach weight,glandular stomach index,liver weight,liver index,lung weight,lung index,kidney weight(P<0.01)and spleen weight(P<0.05)of squabs in group F were significantly higher than those in group C;Feeding fermented feed significantly reduced the conductivity of breast muscle(P<0.01),increased the L*value of breast muscle(P<0.01)and the amino acid composition of breast muscle(P<0.05).The results indicated that the addition of fermented feed to the diet significantly improved the slaughter performance,visceral organ development and meat quality of squabs,which could provide reference for meat pigeon farmers.
