Abstract

The experiment was conducted to explore the effects of combined application of yeast hydrolysate and multi-enzyme preparations or probiotics on the growth performance and serum biochemical indices of nursery piglets. Four hundred and eighty 35-day-old healthy crossed-bred (Duroc×Landrace×Yorkshine) piglets with similar body weight were randomly assigned 5 groups with 8 replicates in each group and 12 piglets in each pen balanced for gender. Using single factor experiment design, the piglets in the control group were fed a basic diet, and the others were fed the basic diet supplemented with 2% plasma protein powder (group 1), 0.5% yeast hydrolysate (group 2), 0.5% yeast hydrolysate+0.02% multi-enzyme preparations (group 3), and 0.5% yeast hydrolysate+0.03% probiotics (group 4), respectively. After 3 days of adaptive phase, the feeding trial was lasted for 25 days, including stage Ⅰ (1 to 14 days) and stage Ⅱ (15 to 25 days). The results showed as follows:1) in stage Ⅰ, compared with the control group, the average daily gain (ADG) and average daily feed intake (ADFI) of the nursery pigs in test groups were improved significantly (P<0.05), also for the ratio of feed to gain (F/G) in group 3 (P<0.05), while F/G in the other groups was between them; in stage Ⅱ, the ADG and F/G in groups had no significant differences (P>0.05), however, compared with the control group, the ADFI of the pigs in group 1 was increased significantly (P<0.05), and the incidences of diarrhea in groups 1, 2, 4 were significantly lower than that in the control group and group 3 (P<0.05); in the whole stage, compared with the control group, the ADG and ADFI of the nursery pigs in group 1 were increased significantly (P<0.05), and the data of those in the other three groups were between them. 2) The serum triglyceride content in the group 3 was significantly decreased compared with the group 2 (P<0.05), and no significant difference was observed in the other serum biochemical indices among groups (P>0.05). In conclusion, plasma protein powder and yeast hydrolysate can improve the growth performance of nursery piglets in varying degrees, and yeast hydrolysate has a potential to replace plasma protein powder in pig diet. The combined application of yeast hydrolysate and probiotics or multi-enzyme preparations do not show a synergistic effect on pigs.
