Feed for enhancing liver function of chickens and application thereof

The invention relates to the technical field of microbial diversity feed processing, and particularly relates to feed for enhancing the liver function of chickens and application thereof. According tothe invention, researches on whitepopinac leadtree leaf extract show that the total phenol content in the extract can be effectively increased by carrying out extraction after lactic acid bacteria are used for pre-fermentation, the result shows that lactic acid bacteria can utilize a substrate to secrete polyphenols under stimulation of the whitepopinac leadtree leaf, so that the total polyphenolcontent is increased, and through feeding experiments, it is found that, after mixed fermentation of the extract and basic feed, the effects of effectively improving the immunity of the chickens andenhancing the liver function of the chickens can be better achieved, wherein the optimal adding amount of the whitepopinac leadtree leaf is 4%-8%; the above-mentioned findings effectively improve theutilization of the whitepopi
