The invention discloses a special feed for improving a laying hen later-period production property and digestive function. The special feed comprises the components by the mass percentage: 42%-66% of corn, 2%-24% of wheat, 5%-22% of soybean meal, 0.5%-2% of fish meal, 1%-5% of bran, 0.5%-5% of a corn protein powder, 6%-10% of stone flour, 0.1%-3% of calcium hydrogen phosphate, 0.01%-0.2% of methionine, 0.2%-0.4% of table salt, 1%-3% of attapulgite clay, 0.01%-0.1% of an emulsifier, 0.05%-0.1% of a compound enzyme preparation, 0.5%-2% of a compound animal health care agent, and 1% of a vitamin and trace element premixed material. The special feed can supplement endogenous digestive enzymes for a laying hen in a later egg-laying period, prolongs the retention time of chyme, regulates the intestinal tract micro-ecological balance of the laying hen, maintains intestinal tract health, increases the laying hen later-period digestive function, and improves the production performance and breeding economic benefits.
Description
Technical field
The present invention relates to field of animal feed, specifically a kind of special feed that improves laying hen later stage production performance and digestive function.
Background technology
China is the country of breeding layer chicken amount maximum in the world, but China's laying hen integral production level is not high at present, exists larger gap with advanced international standard, and the ovipository cycle that is mainly reflected in laying hen is short, and egg production is low.The laying cycle of laying hens of advanced country generally extends to 80 weeks more than age, and total egg production reaches more than 20 kilograms/, and the general feeding period of China laying hen is 65～70 week age, 15 kilograms/of total egg production less thaies.Reason wherein, except feeding and management level is relatively backward, also falls behind relevant with the feed nutrition research of laying hen.
Laying hen declines gradually in (particularly after the 50 week age) laying rate of laying eggs the later stage, is mainly due to due to reproduction and metabolism fail gradually, and the decline of this and laying hen digestive function has certain relation.By supplementing the deficiency of the later stage laying hen endogenous enzymes secretion of laying eggs, improve its digestive function, be expected to improve its production performance.Therefore, the lay eggs special feed formula of later stage laying hen digestive function of a kind of raising of appropriate design, will be conducive to give full play to the productive potentialities of laying hen, improves breeding layer chicken economic benefit.
