Abstract

This study was conducted to evaluate the effects of probiotic fermented apple pomace on growth performance, serum biochemical indicators and fecal microbial flora of weaned piglets. A total of 120 weaned piglets with an average initial body weight of (5.87±0.10) kg were randomly assigned to 5 groups with 3 replicates per group and 8 pigs per replicate. Pigs were allotted to 5 diets, including a basal diet (without antibiotic, negative control group), a basal diet+0.1% hybrid antibiotics (positive control group) and three experimental diets supplemented with probiotic fermented apple pomace at the levels of 4%, 6% and 8% in the basal diet, respectively. The experiment lasted for 35 d. Results showed that, compared with negative control group, antibiotic and 6% probiotic fermented apple pomace supplementation got higher average daily gain and average daily feed intake (P<0.05), but lower feed/gain, fecal E. coli population and diarrhea rate (P<0.05). Antibiotic and 6% probiotic fermented apple pomace supplementation also significantly decreased serum urea nitrogen and total cholesterol contents (P<0.05), while significantly increased growth hormone, insulin, triiodothyronine and thyroxine contents (P<0.05). With the increasing of probiotic fermented apple pomace supplemental level, growth performance, diarrhea rate, fecal E. coli population, serum urea nitrogen, total cholesterol and hormone indices showed quadratic effect changes (P<0.05), with 6% probiotic fermented apple pomace supplementation got the best effect. Compared with positive control group, probiotic fermented apple pomace supplementation extremely significantly increased the total number of fecal bacteria (P<0.01), but did not significantly affect the other indices (P>0.05). It is concluded that dietary supplementation of 6% probiotic fermented apple pomace can improve growth performance and serum endocrine hormones, regulate intestinal flora balance, and reduce fecal E. coli population, diarrhea rate, serum urea nitrogen and cholesterol of weaned piglets.
