抗菌肽对热应激肉鸡生长性能及免疫器官的影响
Effects of antibacterial peptides on growth performance and immune organs of broiler under heat stress condition
摘要
Abstract
In order to verify if antimicrobial peptides(AMP) could modulate growth performance and immune function under heat stress condition,thirty 10-day-old Arbor Acre broiler chickens were randomly grouped into three groups with 10 of each,including control group,heat stress group and AMP treated group(2 mg per bird) with heat stress.Temperature was heated up for 10 days.In result,average body weight gain and FCR in AMP treated group under heat stress condition had significant difference compared to heat stress group (P＜0.01).Pathology observation and immunohistochemistry showed that injury degree and expression of heat stress protein 70(HSP70) in the thymus,spleen and bursa of fabricius of AMP treated birds were lower compared to the heat stress group.In conclusion,AM may reduce injuries of immune organs caused by heat stress and increase a body weight gain in broilers.关键词
