The invention relates to a preparation method of a feed for egg-laying hens at an early
egg laying period. The preparation method comprises the following steps of weighing the following raw materials in parts by weight: 50-58 parts of corn, 8-12 parts of
bran, 20-25 parts of
soybean meal, 1-3 parts of DDGS, 0.5-1 part of
vegetable oil, 1-1.5 parts of
conch meal, 0.3-0.6 part of table salt, 0.1-0.5 part of complex vitamins, 0.1-0.3 part of trace elements, 0.2-0.5 part of gamma-
aminobutyric acid, and 4-6 parts of
traditional Chinese medicine microecology microcapsules, crushing the corn, the
bran and the
soybean meal, then adding remaining raw materials, and performing high-temperature
granulation and cooling so as to prepare a granulated feed. The feed prepared by the preparation method disclosed by the invention has the efficacies of increasing the quantity of beneficial microflora in intestinal tracts, improving immune functions, strengthening the
stress resistance and the
disease resistance of chicken bodies, increasing
egg laying yield, increasing rate of qualified eggs and the like. The feed is simple in preparation method, convenient to use, and free from residues. The preparation method disclosed by the invention has the beneficial effects that
aspartic acid,
glutamic acid and
leucine in the eggs are increased, of which the quantities are 2-3 times of those of market eggs,
tumor necrosis factors are reduced by 41.26%, epidermal growth factors are reduced by 18.59%, the
egg laying rate is increased by 4.68% and 5.72%, the ratio of the feed to the eggs is reduced by 5.28% and 7.56%, and the soft egg and broken egg rate is reduced by 32.17% and 22.46%, so that the feed is saved, the cost is reduced, and the
economic benefits are increased.
