摘    要:研究了半纯合日粮分别添加 0 .4 %的茶多酚 (TP)和果寡糖 (FOS)对 2 8~ 4 2日龄母肉鸡的生产性能等的影响。结果为 ,添加TP和FOS比对照显著降低了死亡率、腹腔脂肪重量和腹腔脂肪率 (P <0 0 5 ) ,并且TP对腹腔脂肪的抑制效果比FOS大 (P <0 0 5 ) ;添加TP显著降低了盲肠菌群的总数、各菌群的数量以及细菌代谢产物的总量(P <0 0 5 ) ;添加FOS不影响盲肠菌群的总数 ,但选择性地显著增加了双歧杆菌 (Bifidobacteri)和真细菌 (Eubacteria)群、降低了其他菌群的数量以及酚类和吲哚的含量 (P <0 0 5 )。试验认为 ,茶多酚和果寡糖具有降低死亡率和腹腔脂肪沉积以及改变盲肠菌群的效果 ,茶多酚表现的是类抗菌素效果 ,即 ,非选择性地降低所有菌群的数量及其代谢产物含量 ,而果寡糖的效果是选择性地增加有益细菌、降低盲肠内挥发性脂肪酸以外的代谢产物的含量

Abstract:This study was conducted to examine the effects of 0.4% tea polyphenols (TP) and 0.4% fructooligosaccharides (FOS) supplementation on performance and caecal microflora counts and its metabolites in female broiler chickens fed semi-purified diets from 28 to 42 day old. As the results, dietary TP and FOS significantly decreased mortality. abdominal fat pad weight and abdominal fat pad weigh/body weight at 42 day old compared to control group (P<0.05). In addition, the inhibitory effect for abdominal fat was larger in TP than in FOS (P<0.05). Dietary TP decreased significantly caecal total microflora counts and counts of each caecal flora population and production of caecal microflora metabolites compared to other groups (P<0.05). Dietary FOS not influenced caecal microflora counts but it selectively increased Bifidobacteri and Eubacteria (P<0.05), decreased other microflora (P<0.05) and concentration of caecal phenols and indole (P<0.0.5) compared to control. Results of this experiment suggest that in the semi-purified diets, TP and FOS have the effects of decreasing mortality, abdominal fat retention and changing caecal caecal flora population, but the TP showed the antibiotics like effects i.e. non selectively decreasing all caecal flora and its metabolites, and the FOS indicated the effects of selectively increasing probiotics and decreasing production of caecal flora metabolites besides volatility fatty acids.
Keywords:broilers  tea polyphenols  fructooligosaccharides  performance  caecal microflora counts  caecal microflora metabolites
