摘　　要：近年来,昆虫抗菌肽(AMPs)作为一种替抗产品,被广泛应用在畜禽生产中,以期提高畜禽生长性能,持续推进畜禽养殖健康发展。为探究不同AMPs水平对欧洲肉鸽种鸽和乳鸽生长性能和肉蛋品质的影响,该试验选取2年龄健康欧洲肉鸽种鸽360对,随机分为4组,空白对照组饮用清水,3个试验组分别在饮水中添加200 g/t、400 g/t、600 g/t的AMPs,试验周期为30天。结果显示,与空白对照组相比,添加600 g/t AMPs组的欧洲肉鸽种鸽的拉稀数、肠炎数和窝料重比显著下降(P<0.05),21天出栏乳鸽重量增加(P<0.05),并且半净膛率、胸肌率、腿肌率和剪切力得到提升(P<0.05),蛋壳钝端厚度下降(P<0.05),而鸽蛋重、横径、纵径、蛋壳强度、蛋白高度、蛋黄重、蛋黄比例和哈氏单位均无显著影响(P>0.05)。试验表明在饮水中添加600g/t AMPs能显著降低欧洲肉鸽种鸽的拉稀、肠炎数和窝料重比,提高了欧洲肉鸽乳鸽的生长性能和屠宰性能,但降低了肌肉嫩度。因此,在欧洲肉鸽种鸽饮水中添加600 g/t AMPs能够提高生产性能,为鸽子健康养殖提供一个良好的途径。In recent years,insect antimicrobial peptides(AMPs),as an antiplastic product,have been widely used in livestock and poultry production,in order to improve the growth performance and continuously promote the healthy development.In order to explore the effects of different AMPs levels on the growth performance,meat and egg quality of European pigeons and squabs,360 pairs of healthy European pigeons were selected and randomly divided into 4 groups.The blank control group was fed with water.Three experimental groups added AMPs at doses of 200 g/t,400 g/t,and 600 g/t respectively to the drinking water,and the experimental period was 30 d.The results showed that the diarrhea number,enteritis and weight ratio of litter decreased(P<0.05),the weight increased(P<0.05),and the half chamber rate,chest muscle rate,leg muscle rate and shear force increased(P<0.05).The thickness of the blunt end of the eggshell decreased(P<0.05)while egg weight,transverse diameter,longitudinal diameter,eggshell strength,protein weight,yolk weight,yolk ratio and Haugh unit(P>0.05).The experiment showed that adding 600 g/t AMPs to drinking water could significantly reduce the diarrhea,enteritis and litter weight ratio of European pigeons,improve the growth performance and slaughter performance,but it reduced the meat tenderness.Therefore,adding 600 g/t AMPs to the drinking water of European pigeon can improve the production performance,providing a good way for pigeon healthy breeding.
