The invention relates to the field of
livestock and poultry breeding, and discloses a laying hen
feed additive based on fermented
broussonetia papyrifera and application of the laying hen
feed additive. The additive is prepared by taking
paper mulberry leaves as a main material, matching with rice husks, wheat
bran and other auxiliary materials, inoculating a microecological preparation containing
lactobacillus plantarum, candida utilis and
bacillus subtilis, and performing anaerobic
fermentation. 4% of the additive is used for daily ration of the aged laying hens, so that the laying rate can be remarkably increased, the dirty egg rate can be reduced, and the egg weight, the
eggshell strength and the
yolk color can be improved; the mechanism is to improve the form of the intestinal tract, enhance the expression of
tight junction protein, regulate immune balance, optimize the structure of
cecum flora and enrich beneficial microorganisms; the
broussonetia papyrifera leaf
feed additive realizes efficient utilization of
broussonetia papyrifera leaf resources, provides a safe and effective functional additive for prolonging the laying period of laying hens and improving the breeding benefits, and has a good application prospect.
