Problems solved by technology

However, at present, the probiotics used for premixes on the market have the following main quality problems: (1) low content of viable bacteria; (2) high moisture content, which is an important factor affecting the quality of probiotics One; (3) Intolerant to antibiotics; (4) Poor stress resistance (such as heat, acid, bile salts, etc.); (5) The probiotic effect is not obvious (acid production, enzyme production, pathogenic bacteria inhibition, etc.)
Due to these quality problems of probiotics, its application effect on animals is limited

Abstract

The invention provides a compound premix which contains selenium-enriched yeast, ferrous-enriched yeast and zinc-enriched yeast, and belongs to the field of premixes. The premix is mainly prepared from the following ingredients of the selenium-enriched yeast, the ferrous-enriched yeast, the zinc-enriched yeast, ferrous sulfate, copper sulfate, zinc sulfate, manganese sulfate, potassium iodide, cobalt chloride, organic trace minerals, multivitamin, pantothenic acid, nicotinic acid, folic acid, biotin, lysine, compound microecologics, ethoxyquin, antioxidant, 50% choline chloride, bentonite and rice chaff. The premix is reasonable in formula, is not added with antibiotics, and contains multi-active probiotics and selenium-enriched yeast powder, ferrous-enriched yeast powder and zinc-enriched yeast powder, the pig survival rate is high, the pig weight is quickly increased, and the feed conversion efficiency is increased. The premix is contributed to improving the intestinal microecological environment of the pig, the intestinal health is maintained, the pig immunity function is improved, the disease occurrence is reduce, and the pig growth is promoted.

Description

technical field [0001] The invention relates to a compound premix for pigs containing selenium-rich yeast, iron-rich yeast and zinc-rich yeast, belonging to the field of feed premix. Background technique [0002] At present, there are many types of compound premixes researched and produced at home and abroad, but most of the premixes have unsatisfactory animal feeding effects, and most of them are added with antibiotics. The disadvantages are becoming more and more obvious, and they do not meet the needs of human beings for greenness and safety. [0003] Selenium is an essential trace element in animals and an important component of glutathione peroxidase (GSK-Px) in organisms. The main biological function is to remove excessive active oxygen free radicals produced in organisms, so It has the ability to improve the immunity of organisms. Selenium can activate thyroid hormones, thereby ensuring the normal growth and development of animals. Selenium-enriched yeast cells can ...
