Functional feed additive for relieving oxidative stress of livestock and poultry and improving intestinal health, and preparation method of functional feed additive

Abstract

The invention provides a functional feed additive for relieving oxidative stress of livestock and poultry and improving intestinal health and a preparation method of the functional feed additive, andbelongs to the field of feed additives. The functional feed additive for relieving oxidative stress of livestock and poultry and improving intestinal health is prepared from the following raw materials: 50 to 60 parts of compound fermented traditional Chinese medicines, 15 to 20 parts of sodium bicarbonate, 5 to 10 parts of soy isoflavone, 3 parts of chromium yeast and 1 to 2 parts of gamma-aminobutyric acid. The preparation method comprises the following steps: fermenting different traditional Chinese medicines for 48-72 hours under the combined action of compound bacteria and compound enzymes according to a recommended formula, drying at low temperature, crushing, and uniformly mixing with other raw materials. By adopting an accurate compound nutrition technology, oxidative stress of livestock and poultry is comprehensively relieved, the intestinal health problem is improved, the anti-stress capability of animals is comprehensively improved, the production performance of animals is improved, and the breeding loss is reduced.

Description

technical field [0001] The invention relates to the field of feed additives, and more specifically relates to a functional feed additive for alleviating oxidative stress of livestock and poultry and improving intestinal health and a preparation method thereof. Background technique [0002] Stress refers to the sum of non-specific physiological responses made by the body due to external environmental stimuli. Oxidative stress is the scavenging rate of free radicals in the body exceeds its production rate, and its oxidative activity exceeds the ability of antioxidant oxidation repair. The imbalance between the oxidation system and the antioxidant system leads to damage to the tissues and cells of the animal body. Current research reports that oxidative stress can induce cardiovascular and other diseases, and pose a serious threat to the health of animals and humans. Factors causing oxidative stress in animals include: high temperature, high-density feeding, group transfer, lo...

Problems solved by technology

Since the plant extracts are extracted through boiling, alcohol-dissolving and other processes, compared with the original traditional Chinese medicine, the content of active ingredients is limited, and compared with fermented traditional Chinese medicine, its application effect is limited

[0005] Chinese Patent Publication CN105211573A discloses a feed additive premix and its application for alleviating intestinal oxidative stress in broilers, including the following components: β-glucosidase 20-50g / kg, glucose oxidase 40-80g / kg, vitamin B25-10g / kg, active yeast selenium 15-30mg / kg, chitosan 30-60g / kg, ghost needle grass extract 50-80g / kg, which can promote the growth of broilers, improve feed utilization, and improve the body's antioxidant capacity , its effect on improving the meat quality of broilers needs to be further verified
