Feeding yeast hydrolysate can improve the growth performance, nutrient digestibility, Lactobacillus count, and reduce drip loss in finishing pigs. The application of 0.1% S. cerevisiae YH enhances the growth efficiency of finishing pigs.
A total of 90 finishing pigs (52 +/- 1.46 kg) were randomly assigned to one of three dietary treatments as: TRT1 [CON (basal diet)], TRT2 [CON + 0.05% yeast hydrolysate (YH)], and TRT3 (CON + 0.1% YH) for an 8 wk trial. Each treatment had six replications and five (three gilts and two barrow) pigs per pen. In weeks 4 and 8, YH supplement linearly increased (P < 0.05) body weight. Moreover, average daily gain was also linearly increased (P < 0.05) with YH supplementation in week 4 and the overall trial period. At the end of the trial, apparent total tract digestibility of dry matter, nitrogen, and gross energy was linearly increased in pigs fed YH supplementation. In addition, fecal Lactobacillus counts, insulin-like growth factor 1 (IGF-1) concentration, and the lean meat percentage were linearly increased by YH supplementation. Also, YH supplementation elicited a linear reduction on drip loss during days 3, 5, and 7. In summary, dietary yeast hydrolysate supplement positively enhanced the growth performance, nutrient digestibility, Lactobacillus count and reduced the drip loss traits of finishing pig. Thus, we infer that the application of 0.1% S. cerevisiae YH can enhance the growth efficiency of finishing pigs.
