Preparation method of traditional Chinese medicine micro-ecological feed additive for laying hens at egg laying later stage

Abstract

The invention relates to a preparation method of a traditional Chinese medicine micro-ecological feed additive for laying hens at an egg laying later stage. The preparation method comprises the following steps of taking traditional Chinese medicines including forsythia suspensa, astragalus membranaceus, radix codonopsis, Chinese angelica, radix isatidis, motherworts, purple perilla, spina date seeds, radix ophiopogonis and licorice roots, performing superfine grinding on the traditional Chinese medicines, adding an alcohol solution, performing boiling over with a strong fire, performing heat preservation with a soft fire, performing cooling, performing filtration, concentrating filtrate, adding white sugar, performing boiling over, performing cooling to normal temperature, inoculating lactobacilli, red tea funguses and bifidobacteria, performing fermentation until white fungus blocks grow, and performing low-temperature concentration on bacterial liquid; and then weighing modified starch, arabic gum, cyclodextrin and syrup, adding the weighed modified starch, the weighed arabic gum, the weighed cyclodextrin and the weighed syrup to the concentrated bacterial liquid, performing stirring during adding, after uniform mixing and stirring, performing high-pressure homogenizing, and performing spray drying so as to obtain the traditional Chinese medicine micro-ecological feed additive. The traditional Chinese medicine micro-ecological feed additive disclosed by the invention has the efficacies of increasing the number of beneficial bacterium groups in intestinal tracts, enhancing immune functions, strengthening stress resistance of chicken bodies, strengthening disease resistance of the chicken bodies, increasing egg production and the like. Compared with a control group, the traditional Chinese medicine micro-ecological feed additive disclosed by the invention has the advantages that the egg laying rate is increased by 4.86% and 7.27%, the feed-egg rate is reduced by 7.65% and 5.82%, and the rate of soft and broken eggs is reduced by 23.64% and 31.72%; feeds are saved, the cost is reduced, and the economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a preparation method of a traditional Chinese medicine micro-ecological feed additive for laying hens in the later stage of laying eggs. Background technique [0002] With the rapid development of modern society and the continuous improvement of people's living standards, eggs have become an indispensable source of protein in every family's life. In order to improve the growth rate, it is very common to use high-energy, high-protein, high-copper, high-iron, and high-calcium methods in feed preparation. However, it also brings some problems to laying hens, such as indigestion and metabolic dysfunction. Feed remuneration is lost, resulting in the death of laying hens, which will cause huge economic losses to the laying hen breeding industry. [0003] Feed is extremely critical to the health of laying hens and to increase egg production. In the prior art, some feed additiv...
