Effects of Eucommia ulmoides Leaves on Growth Performance, Carcass Characters, Antioxidant Capacity and Intestinal Microbial Flora of Finishing Pigs
摘要
Abstract
This experiment was performed to study the effects of dietary Eucommia ulmoides leaves(EUL)on growth performance, carcass characters, antioxidant capacity and intestinal microbial flora, aiming to explorer its application effects in production. Sixty(27 ± 1)kg with no significant difference(P>0.05)finishing pigs (Landrace×Yorkshire)with similar birthday and healthy status were selected and randomly divided into 3 groups with 20 pigs per group. Pigs in control group were fed a basal diet(no antibiotics),and in experimental groups were fed the basic diets with 3% and 4% EUL respectively replaced the same proportion of wheat mid-dings. The experiment was lasting for 102 days. Then, a total of 12 pigs(4 pigs per group)were randomly slaughtered to investigate the carcass characters and meat quality. The results showed as follows: from 1 to 52 days, compared with the control group,4% EUL significantly increased the average daily gain(P<0.05)and extremely significantly decreased the diarrhea rate(P<0.01);from 53 to 102 days,compared with the control group, the feed to gain ratio was extremely significantly decreased in the experimental groups(P<0.01). Compared with the control group,the loin eye area was increased(P>0.05),while the drip loss was extreme-ly significantly decreased(P<0.01)in the experimental groups. The liver glutathione peroxidase activity was significantly or extremely significantly increased(P<0.05 or P<0.01), while the liver malondialdehyde con-tent was extremely significantly decreased(P<0.01)in the experimental groups compared with the control group. Compared with the control group,4% EUL significantly increased the amounts of Escherichia coli and Salmonella(P<0.05),but had no significant effects on the amounts of Lactobacillus and Bifidobacterium(P>0.05). The results indicate that the dietary 4% Eucommia ulmoides leaves can significantly reduce the diarrhea rate, increase the growth performance, improve the carcass characters and meat quality, increase the antioxi-dant capacity, and regulate the intestinal microbial flora of finishing pigs.关键词
