[0002] Jinling Tuxiang chicken is one of the more characteristic chicken breeds in Guangxi. It is praised for its delicious taste and delicate meat. At present, the breeding of this chicken breed is still in a relatively extensive stage, and farmers have not paid attention to this breed. In the breeding process of this breed of chickens, how to improve the immunity of chickens and how to enhance the liver function of chickens is a problem widely studied by those skilled in the art. The liver is the detoxification organ of animals and has It plays a pivotal role. The enhancement of liver function will further enhance the immunity of chickens and make chickens less sick. At present, there are many kinds of plant extracts used to improve the liver function of chickens in th

Embodiment 1
[0016] This embodiment analyzes the polyphenol content extracted by different extraction methods of Leucaena microphylla:
[0017] Extraction method 1: mix fresh leaves of Leucaena microphylla with boiling water according to the solid-to-liquid mass ratio of 1:10, add zeolite, boil for 30 minutes, centrifuge and filter the mixture at room temperature, remove the filtrate and freeze-dry to obtain silver leaf silver Albizia Julibrissin Extract;
[0018] Extraction method 2: dry the leaves of Leucaena microphylla and mix them with boiling water at a solid-to-liquid mass ratio of 1:10. After boiling for 30 minutes, centrifuge and filter the mixture at room temperature, remove the filtrate and freeze-dry to obtain Leucaena microphylla extract thing;
[0019] Extraction method 3: Leucaena microphylla extract The extraction method is: dry the leaves of Leucaena microphylla, mix them with boiling water at a solid-to-liquid mass ratio of 1:10, add zeolite, boil for 30 minutes, and cen...
Embodiment 2
[0028] Prepare chicken feed with embodiment 1 extract and carry out feeding experiment, and blood sampling detects:
[0029] Utilize the extract of embodiment 1 to prepare corresponding chicken feed, specifically as follows:
[0031] Adding extract method A (marked as FA), the timing of adding the extract is before the fermentation of the basal feed, that is, after adding the extract, it is mixed with the basal feed for fermentation, and the added amount is 0%, 2%, and 4% of the mass of the basal feed respectively , 8%, 10%; the fermentation temperature is 37°C, and the fermentation time is 48h.
[0032] Adding the extract method B (marked as FB), the timing of adding the extract is after the fermentation of the basic feed is completed, and the extract is added directly after the fermentatio...

Abstract
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 whitepopinac leadtree leaf as forage grass, and a health-care effect of the chicken feed is improved, meanwhile, compared with commercially available functional feed, the feed is better in safety and health-care effect since there are no other synthetic chemicals in the whole feed.
