Sinek Larvalarından Elde Edilen Antimikrobiyal Peptidlerin Sarı Tüylü Piliçlerin Bağışıklığı Üzerine Etkisi

Bu çalışmanın amacı, sinek larvalarından elde edilen antimikrobiyal peptitlerinin sarı tüylü piliçlerin diyetine takviyesinin bağışıklık biyokimyasal göstergeleri, bağışıklık organ indeksi, ince bağırsak bakterileri ve ince bağırsak mukozal hücre sayısı üzerine etkisini araştırmaktı. Klinik olarak sağlıklı 300 adet 1 günlük sarı tüylü civciv, her grupta 10 hayvan ve her grubun 10 tekrarı olmak üzere rastgele 3 grubua ayrıldı. Gruplar böylelikle, bazal diyet grubu (kontrol grubu), bazal diyet + 100 mg/kg sinek larvası antimikrobiyal peptid (AMP) grubu ve bazal diyet + %15 basitrasin çinko grubu olarak adlandırıldı. Deney süresi 42 gün olarak gerçekleştirildi. Sonuçlar, AMP grubunun albümin, IgG ve IgM seviyesinin kontrol grubuna oranla önemli ölçüde yüksek olduğunu gösterdi (P

Eff ect of Antimicrobial Peptides from Fly Maggots on Immunity of Yellow-feathered Broilers

Abstract:Th e aim of this experiment was to investigate the eff ect of dietary supplementation of fl y maggot antimicrobial peptides on immune biochemical indicators, the eff ect of immune organ index, small intestinal bacteria and small intestinal mucosal cell count in yellow-feathered broilers. Th ree hundred clinically healthy 1-day-old yellow-feathered broilers were randomly divided into 3 treatment groups, 10 replicates in each group and 10 broilers in each replicate. Th e groups were called hereaft er as basal diet group (control group), basal diet + 100 mg/kg fl y maggot antimicrobial peptide (AMPs) group, basal diet + 15% bacitracin zinc group. Th e test period was 42 d. Th e results showed that the contents of albumin, IgG and IgM in the antimicrobial peptide group were significantly higher than those in the control group (P
