Brown-shell egg laying hen feed additive

Abstract

The invention belongs to the field of animal feed and particularly discloses a brown-shell egg laying hen feed additive. The brown-shell egg laying hen feed additive is prepared from the following active ingredients in parts by weight: acanthopanax root, rhizoma corydalis, sodium bicarbonate, radix astragali, radix bupleuri, radix gentianae, folium mori, folium isatidis, golden cypress, cordate houttuynia, platycladi seeds, radix paeoniae alba, suberect spatholobus stem, fructus psoraleae, vitamin A and vitamin D. The feed additive provided by the invention can prevent laying fowl reproductive system infection, avoids simulation to the reproductive systems of laying gens caused by the use of antibiotic medicines, promotes the development and tissue regeneration of the reproductive systems of laying gen, enables the egg production and coloring functions of the laying hens to be normal, and can also prevent the phenomenon that the laying hens are scared and nervous due to environmental stressors and affect egg production and coloring. The medicines act together to facilitate the forming and normal coloring of egg shells and enable brown-shell egg laying hens to produce brown-shell eggs with bright, fresh, clean and uniform-color shells.

Description

(1) Technical field [0001] The invention belongs to the field of animal feed, in particular to a feed additive for brown-shell hens. (2) Background technology [0002] Eggs contain a lot of vitamins, minerals and high-quality protein, and are delicious and easy to process. They are very popular foods. Brown-shell hens are favored by farmers because of their docile temperament, easy management, good cold resistance, stable egg production rate in winter, less pecking habits, low mortality, high egg production, and heavy eggs. The proportion of laying hens raised on farms is as high as 80%. The survey found that when consumers buy brown-shell eggs, they prefer eggs with smooth eggshell surface and bright eggshell color. The occurrence of color spots will affect the commodity value and market competitiveness of brown-shell eggs, and bring losses to farmers. Studies have shown that disease and stress are the most important factors affecting the surface smoothness and color of ...

Problems solved by technology

In the large-scale breeding mode, the population density of brown-shell hens is high, there are many stress factors, and the laying hens are prone to diseases, coupled with the influence of environmental factors, feed factors, drug factors, and physiological factors of laying hens, especially brown-shell hens In the late stage of egg laying, the mucus secretion ability of laying hens' fallopian tubes will decrease, which will easily cause inflammation of the fallopian tubes, resulting in the increase of sand-shell eggs, blood-shell eggs and pink-shell eggs, which will affect the commodity value and market competitiveness of brown-shell eggs
