Feed additive capable of resisting heat stress and relieving oxidative stress injuries and used for broiler chickens

Abstract

The invention discloses a feed additive capable of resisting heat stress and relieving oxidative stress injuries and used for broiler chickens. The feed additive is prepared from the following raw materials in parts by mass: 20-30 parts of compound Chinese herbal medicine extract, 15-20 parts of a yeast culture, 5-10 parts of alpha-ketoglutaric acid, 5-10 parts of glycine betaine, 2-4 parts of sodium hydrogen carbonate, 4-8 parts of ammonium chloride, 3-5 parts of magnesium sulfate and 2-3 parts of chromium picolinate, wherein the compound Chinese herbal medicines comprise garden burnet roots, dandelions, indigowoad roots, spina date seeds, Chinese fevervine herb, herb of shorthorned epimedium, astragalus membranaceus, Chinese angelica, common andrographis herb and liquorice roots. With the adoption of a scientific proportion of a plurality of raw materials with different types, the '1+1>2' synergistic effect is realized; the product has a remarkable effect, the heat stress resisting capability of the broiler chickens under a high-temperature condition can be remarkably improved and the oxidative stress injuries can be relieved; the nutrition digestion rate is improved, the growth is promoted and the feed / gain ratio is reduced; and the feed additive is safe and convenient to use, does not have the problems of drug residues, drug resistance and the like, and has a wide market prospect.

Description

technical field [0001] The invention relates to a broiler feed additive and a preparation method thereof, in particular to a broiler feed additive capable of resisting heat stress and alleviating oxidative stress damage, belonging to the field of feed additives. Background technique [0002] In recent years, in the practice of livestock and poultry production, in order to pursue higher economic benefits, many farms generally adopt intensive feeding methods, making temperature more and more the main environmental factor that causes animal stress. Heat stress refers to the sum of non-specific physiological responses made by the body due to the high temperature stimulation of the external environment. Heat stress can reduce poultry production efficiency, reduce feed utilization, increase morbidity and mortality, and cause huge losses to poultry production. [0003] Broiler chickens have rich feathers, high body temperature, strong metabolism, and no sweat glands on the skin. U...

Problems solved by technology

[0004] At present, in order to alleviate or eliminate the negative effects of heat stress, many scholars at home and abroad have done a lot of research on the impact of anti-heat stress additives on broiler production performance, but most of them use a single additive

Since the current mechanism of heat stress is multifaceted, the effect of a single anti-heat stress additive is limited, and it is difficult to completely or maximize the elimination or mitigation of the effects of heat stress. Many researchers at home and abroad The research on compound additives has already begun, and the combination of various anti-heat stress additives to make it a compound additive is becoming the focus of future research and application
