Effects of Different Fermentation Modes of Rapeseed Meal on Growth Performance,Serum Immunity Indexes,Hormone Levels and Fecal Microorganisms of Fattening Pigs
摘要
Abstract
The purpose of this experiment was to study the effects of different fermentation modes of rapeseed meal on the growth performance,serum immune indexes,hormone levels and fecal microorganisms of finish-ing pigs.A total of 72 healthy fattening pigs of the same month age and weighing about 15 kg were selected and randomly divided into 3 groups,with 4 replicates in each group and 6 pigs in each replicate.The control group(CK group)was fed a basal diet+10%unfermented rapeseed meal,the probiotic fermentation group(FG group)was fed a basal diet+10%probiotic fermented rapeseed meal,and the bacterial enzyme synergistic fermentation group(MPG group)was fed a basal diet+10%bacterial enzyme-co-fermented rapeseed meal.The experimental period was 60 days.The results showed that compared with the CK group,there were no sig-nificant differences in the initial weight,final weight,average daily gain,average daily feed intake and feed-to-gain ratio of fattening pigs in the FG group and MPG group(P＞0.05).Serum immunoglobulin A(IgA),immunoglobulin G(IgG),immunoglobulin M(IgM),and interleukin-2(IL-2)contents in the CK group was significantly higher than that in the CK group(P＜0.05).The serum growth hormone and insulin contents in the FG and MPG groups were significantly higher than those in the CK group(P＜0.05);the serum neu-ropeptide content in the MPG group was significantly higher than that in the FG and CK groups(P＜0.05).Mi-crobial flora analysis showed that feeding fermented feed significantly increased the Simpson index and Shannon index of fecal microorganisms(P＜0.05),but on the 60th day,the relative abundances of Firmicutes and Lac-tobacillus were significantly increased(P＜0.05).In summary,the replacement of part of the basal diet with probiotic fermented rapeseed meal and enzyme-co-fermented rapeseed meal does not affect the growth perform-ance of fattening pigs,but can improve the immunity and hormone levels of fattening pigs and improve the in-testinal flora structure of fattening pigs,promoting the colonization of beneficial bacteria.Considering the cost of fattening pig farming,rapeseed meal fermented with compound probiotics should be used.[Chinese Journal of Animal Nutrition,2025,37(3):1660-1672]关键词
