Special vitamin feed additive for egg-type breeding chicken and preparation method for special vitamin feed

Abstract

The invention relates to a special vitamin feed additive for egg-type breeding chicken and a preparation method for the special vitamin feed. The feed additive is prepared from the following components in parts by weight: 5-8 parts of vitamin A, 5-10 parts of vitamin E, 5-10 parts of vitamin C, 10-30 parts of montmorillonite, 10-20 parts of methionine, 10-20 parts of lysine, 1-5 parts of arsanilic acid, 0.5-1 part of vitamin B2, 0.5-1 part of biotin, 0.5-1 part of nicotinic acid, 5-10 parts of VB6 and 5-10 parts of D-calcium pantothenate. The feed additive disclosed by the invention has capacity of keeping normal dark adaptation, can be used for keeping normal vision to promote biosynthesis of proteins and differentiation of bone cells, promote the growth of a body and development of bones, promote the development of the egg cell, improve the quality of the egg cells and increase the ovulation quantity, improve the sperm quality of breeding chicken, increase the fertility rate of eggs and improve the vigour and quantity of sperm cells, and has effects on increasing the hatching rate, fertility rate and survival rate of chicks of hatching eggs.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a special vitamin feed additive for laying hens and a preparation method thereof. Background technique [0002] Layer breeders, the source of the poultry industry chain, have most of the voice of grandparent chickens in the hands of foreign capital. That is, most of our grandparent chickens basically rely on imports. In 2005, domestic enterprises imported a total of 154,900 Hailan, 60,000 Roman, 21,900 Isa, 17,400 Nick, and 8,800 Hesex, accounting for 58.8%, 22.8%, 8.3%, and 6.6% and 3.4%; the two world-renowned breeds of Hailan and Roman accounted for 81.6% of the Chinese grandparent chicken market, becoming the main body of laying hen breeding in China. And these two kinds of chickens are introduced from abroad.

Problems solved by technology

Successful hatching and fertilization depend on whether the fertilized egg has sufficient nutrition and environmental conditions, while making the egg develop into a viable chick. From a nutritional point of view, the influence of the breeding cock and the breeding hen will affect the hatchability, and others such as deposition The nutrients used by the eggs for the embryos and some physical properties of the eggs that affect the exchange of hatching gas and water will also affect the hatchability. Although we know that some nutritional imbalances or excesses will affect the survival rate of embryos, generally speaking, species Nutritional factors play a major role in the hatchability of chickens. The lack of vitamin A in the early stage affects the formation of embryos and cannot form a circulatory system. The lack of vitamin E affects the development of the chicken brain and is prone to cellulose exudation. If the breeder chicken lacks various vitamins It can lead to decreased semen quality, decreased sperm count, testicular degeneration, decreased sperm motility, and decreased fertilization rate
