- Abstract
The experiment was conducted to study the effect of Bacillus preparation on growth performance, immune performance and fecal flora of weak piglets. Forty-two 28-day-old Sujiang piglets (half in male and female) with the same genetic background, parity and nutrition were randomly divided into two groups, with seven replicates in each group and three piglets in each replicate. Pigs in control group were fed with a basal diet, and those in Bacillus group were fed with a basal diet supplemented with 1 kg/t Bacillus preparation. The experiment lasted for 35 d. The results showed that compared with control group, the average daily gain of piglets in Bacillus preparation group was extremely increased (P<0.01), average daily feed intake was significantly increased (P<0.05), and diarrhea rate was extremely decreased (P<0.01). Compared with control group, the relative abundance of fecal flora Firmicutes of piglets in Bacillus preparation group decreased, while the relative abundance of bacteroidetes and spirochetes increased. The fecal bacteria of piglets in Bacillus preparation group were Prevotella, Treponema, Unspecified Bacteroidales of S24_7 were increased in relative abundance. The relative abundance of Unspecified Lachnospiraceae, Streptococcus, Unspecified Clostridiales, Ruminococcus and Blautia were decreased. The experiment indicates that adding Bacillus to diet can improve the growth performance of weak piglets, and promote the growth and propagation of beneficial bacteria.
