摘　　要：旨在研究不同抗菌肽制剂对肉仔鸡生长性能和屠宰性能的影响,探讨不同抗菌肽制剂替代抗生素的效果。选取1日龄AA肉仔鸡660只,采用单因素随机试验,分为3个试验组,2个对照组。对照组饲喂基础日粮,抗生素组饲喂基础日粮加150 mg·kg^(-1)土霉素,抗菌肽制剂组分别在基础日粮中添加250、500 mg·kg^(-1)和1 000 mg·kg-1的抗菌肽(A)、(B)及(C),试验期6周。结果表明:日粮中添加250 mg·kg^(-1)(A、B、C)与对照组(D)和抗生素组(E)相比均显著提高肉仔鸡的平均日增重及屠宰率,降低料重比(P<0.05)。证实抗菌肽可有效替代抗生素类药物在肉鸡生产中的使用,得到三种抗菌肽的最佳添加剂量为250 mg·kg^(-1)。The effect of different antimicrobial peptides additives replacing antibiotics was investigated to study their influences on broiler growth and slaughter performance. In the growth trial,660 1-day-old healthy Arbor Acre broilers were divided into 3experimental groups and 2 control groups to conduct the single-factor,random test.Each experimental group included high,medium and low levels. One control group was feed with the basal diet,the other control was feed with basal diet add the Antibiotic（150 mg·kg-1 oxytetracycline）. 3 experimental groups were feed with basal diet add Antimicrobial peptides（A）250,（B）500and（C）1 000mg·kg-1 respectively. The growth trial last 6 weeks. The results showed as follows：Compared with two controls（D,E）,the250 mg·kg-1 of three antimicrobial peptides supplemented in diets respectively（A,B,C） could increased average daily gain,improved significantly slaughter performance and increased feed conversion efficiency significantly（P〈0.05）.It concluded that the antibacterial peptides could effectively replace the antibiotic using in poultry production, the best addition dosage of three Antimicrobial peptides（A,B,C）was 250 mg·kg-1.
