Dietary supplementary with soya saponins alleviates the poor intestinal health of broilers caused by coccidia via reshaping the structure of the intestinal flora
The present study was designed to investigate effects of dietary supplementary with SS on the intestinal health of birds challenged with coccidia (CC). 180 male and healthy Cobb 500 broiler chickens with unifrom body weight were randomly divided into 3 treatment groups, those groups were named as the control group (CTR), the coccidia challenged group (CC), and the SS treated group challenged with CC (SS+CC). There were 6 replicates in each group, and 10 birds in each replicate. Birds in the CTR and CC group were fed with the basic diet, and birds in the SS+CC group were fed with the basic diet supplemented with 200 mg/kg SS. The animal trial lasted for 21 days, on day 10 and 12, birds in the CC and SS+CC group were challenged with CC, and birds in the CTR group were treated with normal saline, samples were harvested on day 14, and the growth performance from day 1 to day 10 as well as from day 1 to day 21 were recorded.
