Bu çalışmada, yuınurtadan çıkıştan sonra civcivlerin do ğal barsak florasımn gelişimi ve bu gelişime sterilize edilmiş ve edilmemiş yemin etkisi araştınlmıştır. Civcivlerin barsaklarındaki doğal floramn baskm üyelerinden laktobasil, enterokok ve E.coli 'nin sayımı yapılmıştır. Sterilize edilmemiş yemle beslenen Grup II civcivlerin barsak ve körbarsaldanndaki E.coli sayısı logio , civcivlerin patojenlere duyarl ı olduklan ilk 7 gün boyunca steril yemle beslenen Grup I civcivlere göre yüksek bulunmu ştur. Grup I'de 4.günde 7.178,Grup II'de 8.058 değerleri ile en yüksek düzeye ula şmıştır. Ancak daha sonraki günlerde laktobasil ve enterokok say ılarının yükselmesiyle birlikte E.coh sayı sı Grup I'de 9.günde 4.043'e, Grup Irde 2.955'e dü şmüştür. Denenie süresince laktobasil ve enterokok sayılannda 102-108düzeyinde dalgalanmalar meydana gelmi ştir. Kullanılan yemin gramında 5.677 E. coli, 4.824 laktobasil bulunduğu, fekal streptokok ve Salmonella bulunmadığı belirlenmiştir. Salmonella tvphimurium 60-62 civcivıerde 9. günde kontrol grubuna göre 11.91 g a ğırlık kaybına neden olmuştur.

THE EFFECT OF CHICKEN FEED ON BROILER IlVTESTINAL FLORA

Öz

In this study,the main issue was to investigate the effect of steril and non steril feeding material on the establisment of the natural flora of chick intestine after hatching. Two different groups of experiments were performed. In these experiments Lactobacillus, Enterococcus and Escherichia coli were counted by dilution technique on agar plates. Non steril feeds contributed higher number of E.coli logı o to intestinal flora and cecu ın of the chicks. In general, in the intestines and cecums of chicks fed with non steril feed Group II E.coli counts were more than that of chicks fed with steril feed Group I . during 7 days that the chicks were being sensitive to the pathogens. The highest counts were recorded at 4 th day, which were 7.178 and 8.058, for Group I and Group II, respectively. E.coli counts of Group I decreased to 4.043, Group Il to 2.955 at 9th day. In addition that the number of Lactobacillus and Enterococcus number were waved between 10 2and 108 . It was found that the number of E.coli and lactobacilli were 5.677 and 4.824, respectively, and fecal streptococci and Salmonella did not exist in the feed. Artificially inoculated Salmonella tvphimurium 60-62 caused 11.91 g weight decrease compared to control chicks at 9th day.
