▼a The objective of experiment 1 was to determine the effects of Bacillus-based DFMs on growth performance, gut health, immune status, and oxidative stress status in nursery pigs. Three-hundred and sixty nursery pigs were randomly assigned to 1 of |

▼a The objective of experiment 2 was to determine the optimal dose of Bacillus subtilis 29784 to improve growth performance of nursery pigs. Fifty-four newly weaned piglets were randomly allotted to 1 of 3 treatments: 1) T1: Basal diet |

▼a The objective of experiment 3 was to determine the effects of Bacillus subtilis 29784 on gut health and prevention of post-weaning diarrhea caused by F18+ Escherichia coli. Forty nursery pigs were randomly allotted to 1 of 4 treatments with ini |
