Description

Laying hen compound feed for improving laying rate and hatchability and preparation method thereof
Technical Field
The invention belongs to the technical field of feeds, and particularly relates to a compound feed for egg-laying hens, which is capable of improving laying rate and hatchability, and a preparation method of the compound feed.
Background
The laying rate and the hatchability of the laying hens are important indexes for measuring the value of the laying hens and the economic benefit of a breeding farm. But the influence factors are many, including feeding management, feed nutrition level, hatching management and the like. A great deal of research is carried out by a plurality of scholars and researchers, wherein a great deal of reports are carried out on nutrition for improving the laying rate and the hatchability of the laying hens, and the influences of metabolic energy, amino acid, vitamin, trace elements and the like on the reproductive performance of the laying hens in the laying period of the laying hens are mainly determined. Under the condition of good management, immunity and other conditions, the laying rate and the hatching rate of the egg-laying hens are easily influenced by the nutrient level of the feed. If the nutrition level is low and the nutrition is unbalanced, the problems of low laying rate, short laying period, small egg weight and the like can be caused. If the nutrient level is too high, the egg weight of the hatching eggs is easily too large, and the hatching rate of the hatching eggs is reduced if the egg weight is too large. Therefore, the feed nutrient level of egg breeders has a significant impact on egg production, egg weight, hatchability, and the like.
Most of egg-laying hen feeds in the current market are not set according to the nutritional requirements of varieties, the price is low, and the nutrition ratio is unbalanced. In addition, a large number of egg breeding hens use self-prepared feed, whether basic crude protein and metabolic energy are met is usually only considered, the requirements of other aspects of the egg breeding hens are neglected, the production process is lagged behind, the mixing uniformity and the crushing granularity cannot reach the standard, and the phenomenon of unscientific production exists. These all affect the laying rate and hatchability of the heavy laying hens.
Compared with commercial laying hens, the research on the feed for the laying hens in the prior art is rare, and through retrieval, the following patents with high correlation degree are found:
the invention patent CN 105595008A discloses a laying period compound feed for improving the healthy chick rate of an egg-laying chicken and a preparation method thereof, and the compound feed is mainly prepared by mixing grains, soybean meal, corn protein powder, rice bran meal, alfalfa meal, vegetable oil, amino acid, compound enzyme, prebiotics, compound organic trace elements and compound premix according to a certain weight ratio. The invention aims to improve the fertility rate, the hatchability and the healthy chick rate in the feeding process of the existing egg breeding hens, but does not relate to the improvement of the laying rate of the egg breeding hens.
The invention patent CN 108902533A discloses a layer feed and a processing method thereof, which is mainly formed by mixing corn, puffed soybean meal, corn germ cake, corn germ meal, xylo-oligosaccharide, organic calcium, stone grains, calcium hydrophosphate, soybean oil, a compound Chinese herbal medicine preparation, a compound probiotic fermented feed, dihydropyridine and a layer premix according to the weight proportion. The dihydrodipyridine used in the invention is a veterinary growth-promoting additive, cannot be popularized and used in feed enterprises, is only used in farms, and becomes a limiting factor of the invention.
The invention patent CN 102599378A discloses a compound feed for meat type chickens in the laying period and a preparation method thereof, and the compound feed is mainly obtained by mixing raw materials of corn, wheat bran, soybean meal, corn protein powder, stone powder, monocalcium phosphate, soybean oil, lysine, methionine, salt, sodium bicarbonate, choline, betaine, multivitamin, ferment HT, selenomethionine, mosquitocide, phytase and premix according to a certain weight percentage. The compound feed for broiler chickens in the laying period does not contain any pigment, has high nutrient content and strong anti-stress capability, enables the breeding hens to grow fast, and enables the breeding hens to have high yield. The feed for broiler breeders in the laying period disclosed by the patent is made for meeting the nutritional requirements of broiler breeders, and the broiler breeders are greatly different from the egg breeders in the invention in physiological characteristics, feed intake, nutritional standards, egg laying performance and egg quality requirements.

medicated leaven contains yeast, amylase, ergosterol, volatile oil, fat, protein, vitamin B and other components, and thus has excellent functions of promoting digestion, eliminating stagnation, regulating stomach function, stopping vomiting, relieving flatulence, treating dysentery, stimulating appetite, promoting metabolism, etc.
The fructus crataegi contains vitamins, maslinic acid, tartaric acid, citric acid, malic acid, etc., and also contains flavonoid, lactone, saccharide, protein, fat and minerals such as calcium, phosphorus, iron, etc., and the lipolytic enzyme contained in fructus crataegi can promote digestion of fat food. Promoting gastric secretion and increasing enzyme in stomach. The traditional Chinese medicine considers that the hawthorn has the effects of removing food retention, resolving stagnation, astringing, stopping dysentery, promoting blood circulation, removing blood stasis and the like.
Chenpi fen is usually indicated for abdominal distention and fullness, vomiting and diarrhea due to poor appetite, cough with profuse sputum, and is combined with shan Zha and Shen Qu for abdominal distention and pain due to food stagnation and qi stagnation. The hawthorn, the dried orange peel, the acanthopanax root and the like can reduce the cholesterol and total lipid content in eggs, improve the protein and calcium content, improve the eggshell hardness, reduce the breakage rate of the eggs and deepen the color and luster of the egg yolks. Acanthopanax senticosus can also enhance the anti-stress capability of the laying hens.
