Title: Effects of Ultrafine Chinese Herb on Microflora and Intestinal Mucosa Structure in Weaned Piglets
Abstract:For the development of a safe, efficient and environmentally friendly Chinese herb additive in weaned piglets, 72 Duroc-Landrace-Yorkshire weaned piglets which were randomly divided into four groups, ...For the development of a safe, efficient and environmentally friendly Chinese herb additive in weaned piglets, 72 Duroc-Landrace-Yorkshire weaned piglets which were randomly divided into four groups, each treatment had 3 replicates and each consisting of 6 piglets. The control group was fed the basal diet. Antibiotic group was fed the basal diet plus antibiotics. Chinese herbs Ⅰgroup was added 1% Chinese herbs formula Ⅰ,Chinese herbsⅡ group was added 1% Chinese herbs formulaⅡ. Feeding trial lasted 28 days, and the intestinal pH, microflora, intestinal mucosal villus height and crypt depth were measured. The results were as followed:Chinese herbsⅡ group are better than Chinese herbsⅠ group. Compared with the control group, Chinese herbsⅡ group can significantly reduce the pH value in the jejunum and ileum(P0.05), but little effect on the pH value of the cecum(P0.05). Compared with the control group, Chinese herbsⅡ group can significantly reduce the E.coli concentration(P0.01) and improve the lactobacilli concentration(P0.05) in the jejunum, ileum and cecum,Chinese herbsⅡ group can also significantly increase the bifidobacteria concentration in the jejunum and ileum(P0.05), but little effect on the bifidobacteria concentration in the cecum(P0.05). Compared with the control group,Chinese herbsⅡ group can significantly improve the duodenal villus height(P0.05) and significantly increase the villus height in the jejunum and ileum(P0.01). Compared with the control group, Chinese herbsⅡ group can significantly increase the ratio of villus height and crypt depth(P0.01), but little effect on the crypt depth(P0.05).These indicate that Chinese herbsⅡ group can stimulate the intestinal lactobacilli and bifidobacteria proliferation,inhibit the proliferation of E. coli and effectively improve the intestinal mucosal morphology.Read More
