Broyler rasyonlarında probiyotik ve sinbiyotik kullanılmasının broyler performans ve bağırsakhistomorfolojisi üzerine etkisi

Abstract

Paenibacillus xylanexedens’in tek başına veya inulin veya laktuloz ile birlikte kullanılmasının erkek broylerlerin büyüme performansı ve bağırsak histomorfolojisi üzerine olan etkisi incelendi. Toplamda 168 adet günlük erkek civciv dört deneme grubuna ayrıldı: C, bazal rasyon (kontrol); P, 1×109 cfu/kg-yem P. xylanexedens; IN, 1×109 cfu/kg-yem P. xylanexedens ve %1 inulin; LAC, 1×109 cfu/kg-yem P. xylanexedens ve %0.5 laktuloz. P. xylanexedens ve sinbiyotik ilavesinin 1-21. günlerde broyler canlı ağırlık artışını (P<0.001) ve yemden yararlanma oranını (P=0.023) önemli düzeyde arttırdığı sonucuna varıldı. Tüm araştırma periyodu dikkate alındığında sinbiyotik ilavesinin canlı ağırlık artışını önemli ölçüde (P=0.013) etkilediği görüldü. Araştırmanın 42. gününde probiyotik ve sinbiyotik ilave edilen gruplarda ileum villus yüksekliğinin daha fazla olduğu tespit edildi (P=0.047). Sonuç olarak, P. xylanexedens’in broyler büyüme performansını ve bağırsak histomorfolojisini olumlu yönde etkilediği ve rasyonlarında probiyotik yem katkı maddesi olarak kullanılabileceği görüldü

Effects of dietary probiotic and synbiotic supplementation on broiler growth performance and intestinal histomorphology

Abstract

The effects of Paenibacillus xylanexedens, alone or in combination with inulin and lactulose were evaluated on growth performance and intestinal histomorphology of male broilers. A total of 168 one-day-old male broiler chickens were randomly allocated to 4 experimental groups as follows: C, basal diet (control; without supplementation); P, 1×109 cfu/kg-feed P. xylanexedens; IN, 1×109 cfu/kg-feed P. xylanexedens and 1% inulin; LAC, 1×109 cfu/kg-feed P. xylanexedens and 0.5% lactulose. Addition of P. xylanexedens and synbiotics significantly increased broiler body weight gain (P<0.001) and feed conversion ratio (P=0.023) from 1 to 21 day of age. Moreover, a significant increase in body weight gain was observed when birds were fed with synbiotic supplemented diets during the overall experimental period (P=0.013). The addition of probiotic and synbiotics increased (P=0.047) villus height in ileum on day 42. Our results indicate that P. xylanexedens can be used as a probiotic feed additive in broiler diets and can improve broiler performance and intestinal histomorphology
