Feed additive capable of enhancing immunity of laying hens and promoting yield increase

Abstract

The invention provides a feed additive capable of enhancing immunity of laying hens and promoting yield increase. The feed additive is prepared from the following raw materials in parts by weight: 90-110 parts of astragalus membranaceus, 70-90 parts of motherwort, 40-60 parts of epimedium, 30-50 parts of Chinese angelica, 30-50 parts of ligusticum wallichii, 30-50 parts of bighead atractylodes rhizomes, 30-50 parts of peach kernels, 20-40 parts of prepared ginger and 70-90 parts of licorice roots. The feed additive disclosed by the invention contains various substances including amino acids, vitamins, trace elements and the like, so that the metabolism of organisms can be promoted, and the synthesis of protein and enzymes is promoted; therefore, the growth is promoted, the fecundity and the production properties are improved, diseases are prevented and treated, the utilization rate of feeds is increased, the raising benefits are increased, the immunity of the laying hens is enhanced, and besides, the egg laying rate of the laying hens is increased.

Description

technical field [0001] The invention relates to the technical field of poultry feed, in particular to a feed additive for improving the immunity of laying hens and promoting production. Background technique [0002] In order to achieve the goal of high efficiency and low cost, modern laying hen breeding technology often adopts highly intensive farming models and management methods. In a high-density feeding environment, it is easy to cause the stress response of laying hens, as well as problems such as decreased egg production rate and decreased immunity caused by hormone imbalance in laying hens. Once the laying hens are stressed, in addition to improving the management of the feeding environment, the most important and most direct thing is to improve the feed. One of the important means is the use of feed additives. [0003] Chinese herbal medicine feed additives contain a variety of amino acids, vitamins, trace elements and other substances, which can enhance the metabo...
