Problems solved by technology

In order to prevent the decline of egg production performance of laying hens, people often add some antibiotics or even hormones, which will not only easily lead to the enhancement of bacterial resistance, but even endanger human health
In addition, although ingredients such as vitamins and trace elements can play a certain role, they are mostly supplemented from feed nutrients, which cannot improve the physiological functions of laying hens themselves.
Chinese herbal medicines have incomparable advantages over other ingredients in improving the production performance of laying hens. At present, most of the egg-enhancing products of laying hens are traditional Chinese medicine powders. In practical applications, powders often affect feed intake due to the large amount of mixing materials and strong odor. In addition, Its absorption rate is low and its effect is unstable

Abstract

The invention relates to a traditional Chinese medicinal extract feed additive which is prepared from the following raw materials in parts by weight: 200-300 parts of a folium cortex eucommiae leaf extract, 80-120 parts of a soybean extract and 580-720 parts of corncob powder. All the components of the traditional Chinese medicinal extract feed additive work cooperatively, and the effects supplement each other and are scientifically matched; the content of a flavonoids compound serving as an effective component is high, and the flavonoids compound is natural, safe and free of side effect; and under the condition that drinking and intake of laying hens are not affected, the laying performance of the laying hens is effectively improved, so that the whole breeding benefit is enhanced. The invention further provides a preparation method for the traditional Chinese medicinal extract feed additive.

Description

technical field [0001] The invention belongs to the field of animal feed additives, and relates to a traditional Chinese medicine extract feed additive and a preparation method thereof. Background technique [0002] The poultry farming industry has developed rapidly in recent years, with larger and larger farming scales and higher degrees of intensification. As laying hens are raised, they are often affected by various factors, such as environmental factors, feed mildew factors, and various stresses, due to limited cage space and excessive density. Chicken flocks are affected by many aspects, which will lead to decreased digestive system and reproductive function, low feed utilization rate, poor gastrointestinal function, decreased liver and kidney function, and severe oxidative stress in the body, resulting in decreased egg production, increased soft broken deformed eggs, The peak egg production period is too short, the immunity is low, the incidence rate is too high, and ...
