A kind of compound feed during the laying period that improves the healthy chick rate of layer breeders and its preparation method

Abstract

The invention belongs to the technical field of feed, and in particular relates to a compound feed for layer breeder hens during the laying period which improves the healthy chick rate, and to a preparation method of the feed. The compound feed is mainly prepared from the following raw materials in parts by weight: 50-65 parts of cereals, 15-25 parts of soybean meal, 1-5 parts of corn gluten meal, 1-6 parts of rice bran meal, 2-6 parts of alfalfa powder, 1-3 parts of vegetable oil, 0.35-0.7 parts of amino acids, 0.05-0.1 parts of complex enzymes, 0.05-0.2 parts of prebiotics, 0.01-0.03 parts of 25-hydroxycholecalciferol, 0.01-0.3 parts of β-carotene, compound organic trace elements 0.03‑0.08 part, 1 part of compound premix. The sufficient and effective energy, amino acid, mineral nutrition and prebiotics of the present invention can ensure the requirement of maximum laying potential of layer breeder hens, high egg production rate and suitable egg weight, and high healthy chick rate of layer breeder hens.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a compound feed for layer breeder hens during the laying period which improves the healthy chick rate, and to a preparation method of the feed. Background technique [0002] The healthy chick rate of laying hens is an important indicator to measure the value of laying hens and the economic benefits of chicken farms. There are many influencing factors, including feeding management, egg management and hatching management, etc., which all affect the fertilization rate, hatching rate, and then affect the health. The level of chick rate. There are many reports on the nutrition of layer breeders that increase the fertilization rate and the nutrition of layer breeders that increase the hatchability. The predecessors have done a lot of research on the nutrition of breeders, and determined the effects of metabolizable energy, amino acids, and vitamins on the reproductive performa...

AI Technical Summary

Problems solved by technology

This invention only starts from part of the needs of layer breeders, and the nutritional composition is unscientific and unbalanced, which cannot meet the nutritional needs of layer breeders during the laying period

The potato dry powder and oil content used in this patent are high in content, digest quickly, and are not digested synchronously with other nutrients, affecting the digestion and absorption of other active ingredients such as amino acids, and the nutrition is extremely unbalanced, which seriously affects the health of breeders

[0007] At present, the egg breeder feed on the market does not meet the requirements of the species, the price is low, and the nutritional ratio is unbalanced and unscientific

There are still many egg breeder companies that produce feed by themselves, and the mixing uniformity and crushing particle size are not up to the standard, and there is an unscientific production phenomenon
