Breeder chicken physiological function regulator

Abstract

The invention relates to a physiological function regulator used for breeding hens in poultry rearing, which solves the problem that productivity of the breeding hens declines in later breeding period. The physiological function regulator used for the breeding hens comprises the following materials with the weight proportion: 80-85 parts of black tea dust, 5-7 parts of astragalus root and 6-8 parts of angelica; the raw materials are mixed, crushed, and sieved by a 60-mesh sieve, thereby obtaining the regulator; as for usage amount, the physiological function regulator used for the breeding hens weighs less than 0.59 percent of the total feed is added into the breeding hens feed and well mixed. Physiological and biochemical indicators of the blood in the breeding hens are improved by usingthe regulator; the average laying rate is increased by 2.05 percent; the thickness of the eggshell has no obvious change, the weight proportion of the egg yolk to the egg is increased by 7.80 percentin average, and the color of the egg yolk is increased by 5.87 percent in average. In Haugh, the rate that the eggs reach A level is increased by 6.18 percent, the fertility rate of the produced breeding eggs is increased by 6.04 percent, the hatched rate of chickling is increased by 4.88 percent, the rate of healthy chickling is increased by 1.58 percent and the rate of healthy chickling obtained from breeding eggs for hatching is increased by 5.13 percent.

Description

technical field [0001] The invention relates to a preparation for poultry feeding, specifically a breeder breeding performance regulator. Background technique [0002] At present, due to the degeneration of ovarian function in the later stage of laying eggs, the level of estrogen in the body decreases, resulting in a decrease in egg production rate, fertilization rate and hatching rate. Generally, the egg production rate gradually drops from above 80% to below 70%, until it ends at 55%-60%. Guo Jun said in the article "Incubation Management of Broiler Eggs in the Late Laying Period" of "China Poultry" Volume 24, Issue 4, 2002: "It was found in the process of technical services for many years that the early embryo mortality rate of eggs in the late laying period is relatively low. High (>7%)." However, as the breeder ages and the egg weight increases, the hatched chicks have greater tolerance and weigh more than chicks hatched from younger breeder eggs, so feeding older b...
