摘要
采用4×2（海藻粉×抗菌肽）完全随机试验设计，研究日粮添加不同水平的海藻粉（0．0％、1．0％、3．0％、5．0％）和抗菌肽（300 mg/kg、600 mg/kg）对蛋鸡不同产蛋期（24～27周龄和28～31周龄）产蛋性能的影响。结果表明：（1）日粮海藻粉的添加水平显著提高了产蛋率和料蛋比（P＜0．05）。（2）抗菌肽添加水平在28～31周龄显著提高了产蛋率（P＜0．05）。（3）海藻粉和抗菌肽互作效应显著提高了产蛋率和料蛋比（P＜0．05）。结果提示，海藻粉和抗菌肽对蛋鸡产蛋性能的影响存在互作效应，以海藻粉5％、抗菌肽300 mg/kg水平组合最为理想。
A 4 ×2（seaweed powder ×antibacterial peptides）random experiment was designed to investigate the effect of different dietary levels of seaweed powder（0.0%,1.0%,3.0%,5.0%）and antibacterial peptides （300 mg/kg、600 mg/kg ）on laying performance of Hyline Brown layer at 24~27 week-old and 28~3 1 week-old.Results indicated：（1）The supplementation of dietary seaweed powder significantly increased laying rate and ratio of feed to egg（P＆lt;0. 05）.（2）The supplementation of dietary antibacterial peptides significantly increased laying rate at 28 ~31 week-old. （P＆lt;0.05）.（3）Interaction between seaweed powder and antibacterial peptides significantly increased laying rate and ratio of feed to egg （P＆lt;0.05）.It is concluded that seaweed powder and antibacterial peptides interaction had a signifi-cant effect on the laying performance in Hyline Brown layer.The suitable level of dietary is 5% seaweed powder and 300 mg/kg antibacterial peptides respectively in the whole period.
