Abstract：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.
