The invention relates to the technical field of feeds, and discloses a functional
probiotic-based daily ration formula for laying hens and a preparation method of the functional
probiotic-based daily ration formula. Wheat middling is used as daily ration of laying hens, so that the function of reducing the breeding cost is achieved. The laying hen feed is prepared from the following raw materials in parts by weight: corn,
soybean meal, 15-30 parts of wheat middling, 0.1-0.2 part of compound
probiotic dry powder, 5% laying hen premix and the like according to a scientific proportion, and the compound functional probiotic
dry powder is prepared by compounding
bacillus licheniformis,
bacillus subtilis and
enterococcus faecalis. According to the laying hen feed disclosed by the invention, bacillus revives and reproduces in intestinal tracts of laying hens and secretes hydrolases such as
xylanase and
protease in situ, anti-nutritional factors such as non-
starch polysaccharides in wheat middling are efficiently degraded, and wrapped
nutrient substances are released; and the
lactic acid bacteria regulate the intestinal microecological balance through competitive rejection and maintain the intestinal health. The daily ration can significantly improve the
utilization rate of wheat middling, improve the feed-egg ratio, effectively improve the
eggshell strength and quality while ensuring the
egg laying performance, and assist breeding cost reduction and efficiency improvement.
