Preparation process for premix capable of reducing shell breaking rate of Hailan grey chicken

Abstract

The invention discloses a preparation process for a premix capable of reducing the shell breaking rate of a Hailan grey chicken, and belongs to the technical field of feed preparation. According to the scheme, the Hailan grey chicken can be supplemented with calcium, phosphorus, vitamins and other nutrient elements through the premix, so that the hardness and thickness of eggshells are effectivelyimproved and the shell breaking rate is effectively reduced; meanwhile, when the premix is prepared, due to the use of a stone core wrapping bag, a friction-assisting stone core wrapped with premix particles exists in the finished premix; after the Hailan grey chicken eats the premix, the friction-assisting stone core is loosened after being softened by digestive juice and can serve as a calciumsupplement substance, so that the eggshells are thicker and harder, and the shell breaking rate is reduced; and food can be ground in the chicken gizzard in an auxiliary mode, and digestive absorptionof the Hailan grey chicken to the finished premix is assisted, so that the laying rate of the Hailan grey chicken is higher, and the shell breaking rate of the Hailan grey chicken is lower.

Description

technical field [0001] The invention relates to the technical field of feed preparation, and more specifically relates to a premix preparation process for reducing the shell breaking rate of Hailan ash. Background technique [0002] Hailan gray chicken is a commercial supporting line of pink-shell layer hens bred by many egg breeder farms in my country, such as Beijing Deqingyuan and Shandong Yisheng, which were introduced from the United States Hailan International Company. [0003] The male parent of Hailan Hui is the same as the male parent of Hailan Brown Chicken (see the male parent of Hailan Brown Chicken for the appearance characteristics of the male parent). The color of the shin is yellow, and the body is light, small and delicate. The fluff of the newborn chicks of Hailan gray is goose yellow, with small black spots distributed all over the body. The male and female can be identified by feather speed. The back feathers of adult chickens are grayish red, and the wi...

Problems solved by technology

[0004] During the laying process of the existing Hailan gray chickens, due to problems such as many eggs being squeezed between each other or thin eggshells, the eggshells of the Hailan gray chickens are likely to break when laying eggs, causing the eggs to be wasted , and the eggshell damage is easy to breed bacteria, affecting the health of the eater
