陕西青脚麻肉鸡肠道定殖菌的生活状态和分布研究

Abstract

Abstract: In the present study，we determined activities and distribution of bacterial colonization in the intestine of Shaanxi Qingjiaoma chickens.The microorganisms were cultivated and counted by gradient dilution and tissue culture method.The results showed that the middle and downside portions of small intestine contained Bacillus at a concentration of 6.5×10⁵ CFU/mL. Saccharomyces was found in cesium at a concentration of 6.8×10⁴ CFU/mL.Particularly，the downside portion of duodenum contained Lactobacillus at a concentration of 8.6×10⁴ CFU/mL.Clearly，our results indicated that the Bacillus were rich in the intestine of Shaanxi Qingjiaoma chickens.In contrast，Saccharomyces and Lactobacillus as probiotics were less rich in the intestine.

Key words: probiotics; intestine; bacterial colonization; Shaanxi Qingjiaoma chickens
