The invention discloses a fermented
traditional Chinese medicine additive for improving the production performance of laying fowls and a preparation method thereof, and belongs to the technical field of feed additives. The additive specifically comprises the following components in parts by weight: 5-15 parts of liquorice, 15-25 parts of
pericarpium citri reticulatae, 25-35 parts of hawthorns, 25-35 parts of Chinese yams, 25-35 parts of divaricate
saposhnikovia roots, 55-65 parts of bighead atractylodes rhizomes, 55-65 parts of
astragalus membranaceus, 25-35 parts of herba epimedii and 55-65 parts of
radix isatidis. The method comprises the following steps: adding
yeast and medicated leaven into the liquorice, the
pericarpium citri reticulatae, the hawthorns and the Chinese yams, performing aerobic liquid
fermentation, then adding the divaricate
saposhnikovia roots, the bighead atractylodes rhizomes, the
astragalus membranaceus, the herba epimedii and the
radix isatidis, performing anaerobic liquid
fermentation to obtain an intermediate
fermentation product, adding
lactobacillus plantarum,
bacillus subtilis and
bacillus licheniformis into the intermediate fermentation product, and performing
solid fermentation to obtain the
traditional Chinese medicine additive. According to the invention, the absorption and
utilization rate of laying fowls on
traditional Chinese medicine components is improved, the medicinal
efficacy is improved, and the problem of laying
rate reduction caused by deficiency of qi and blood and abnormal fallopian tubes of the laying fowls is solved.
