Effect of MCFA and probiotic on piglet performance, as well as gut microbiology, was estimated.
Capric acid improved piglet BWG after 28th day of life.
Probiotic lowered the weight gain at 28–56th day but increased it later.
Probiotic increased villus width and crypt depth in the epithelium of small intestine.
Strong antibacterial activity: acids against E. coli and probiotic vs. C.perfringens.
