Problems solved by technology

There are also research reports on the use of Chinese herbal additives, such as the use of Acanthopanax extract, purslane, dandelion, Huoxiang, honeysuckle, isatidis, atractylodes, gentian, etc., but it is limited to the research on laying performance of laying hens. Targeted selection of natural plants as additives to fundamentally improve the body's neuro-endocrine-immune network system to prevent heat stress by improving the immunity of laying hens is rarely reported. Micron level, to overcome the defects of large dosage, low absorption, and poor effect of general plant additives, so that it has better absorption, adsorption, solubility, chemical activity, and biological activity. The research on the molecular mechanism of additives to improve immunity and regulate body fluid balance is completely blank

Embodiment 1

[0021] The natural plant anti-heat stress feed additive for chickens is prepared, comprising the following steps:

[0022] (1) The mass percentage is 30% astragalus (special grade), 35% licorice (system), 7% Prunella vulgaris (system), 5% reed rhizome (system), 5% raw gypsum , 8% mint (single slices) are dried in an electric constant temperature blast drying oven, so that the moisture of the above raw materials is reduced to below 10%;

[0023] (2) Coarsely pulverize the raw materials obtained in step (1) in a pulverizer to obtain a coarse powder, the particle size of which is 180 microns;

[0024] (3) The coarse powder is ultrafinely pulverized in a micropowder ball mill to obtain superfine powder, and the wild plant feed additive is prepared. The particle size of the micropowder is less than 10 microns, accounting for 70% of the whole micropowder. The process parameters of the micropowder ball mill are: the ball milling time is 30 minutes, the weight ratio of the ball to m...

Abstract

The invention discloses a natural plant chicken heat stress resistant feed addictive and a preparation method thereof, and belongs to the technical field of laying chicken heat stress. The addictive is prepared by the following components in percentage by weight: 30-40 percent of astragalus mongholicus, 25-35 percent of liquorice, 5-10 percent of selfheal, 5-10 percent of rhizoma phragmitis, 3-5 percent of gypsum and 5-10 percent of mint. According to the natural plant chicken heat stress resistant feed addictive prepared by using the preparation method, the problem of the laying chicken heat stress can be radically solved.

Description

technical field [0001] The invention belongs to the technical field of anti-heat stress of laying hens, and in particular relates to a natural plant anti-heat stress feed additive for chickens and a preparation method thereof. Background technique [0002] Due to the heat stress of laying hens caused by high temperature in summer in southern my country, the egg production performance of laying hens, such as feed intake, egg production rate, feed utilization rate, etc., has been sharply reduced and caused serious damage to the health of laying hens. An important factor restricting the development of the laying hen industry. When the ambient temperature exceeds the optimum temperature (23°C) of the laying hens, the feed intake of the laying hens will decrease, the egg production rate will drop by 28.9%, the morbidity and mortality will increase by nearly 20 times, the egg weight will decrease, the eggshell will become thinner, The fertilization rate and hatching rate of breedi...
