In conclusion,both ALA,and LAC (0.5,and/or 1 g /kg, respectively) supplementation in creased growth performance and ATTD of nutrients in weaning piglets.Moreover,diet with ALA supplementation increased blood parameters (i.e.Hb,TIBS, and HCT,and RBC), whereas LAC supplementation improved gut health and reduced fecal NH3 gas emissions. These results in dicatedthat ALA,and LAC supplementation might have a positive role on performance through Hb biosynthesis, and prebiotic mechanisms in nursery piglets,respectively.
