Problems solved by technology

But at present, the probiotics used for premixes on the market have the main quality problems in the following aspects: (1) the type of strain is single; (2) the content of viable bacteria is low; (3) the moisture content is high, which affects One of the important factors of the quality of probiotics; (4) intolerance to antibiotics; (5) unstable to gastric acid and bile salts, etc.
[0003] Enterococcus faecalis and Bacillus licheniformis belong to one of the strains of microbial feed additives approved by the Ministry of Agriculture, but Yeast of M. As a feed additive and added to the premix, there is no research and application report

Abstract

The invention relates to a composite premix for a pig, belonging to the field of premix. The premix provided by the invention comprises the following main ingredients of: vitamin A, vitamin D3, vitamin E, vitamin K3, vitamin B1, vitamin B2, vitamin B6, vitamin B12, nicotinic acid, D-calcium pantothenate, biotin, choline chloride, copper sulfate, ferrous sulphate, zinc sulfate, manganese sulfate, potassium iodide premix, sodium selenite premix, an antioxidant, a composite microbioecological agent, bentonite and rice chaff. The premix provided by the invention has the advantages of reasonable prescription, no addition of antibiotic, multiple probiotics and high viable bacteria content; and it is proved by an animal breeding laboratory that the composite premix has an ideal breeding effect and can ensure that the pig has a high yield, a fast weight growth and high meat ratio. The composite premix provided by the invention has a good promoting effect on pig growth and health condition, can satisfy requirements on the current broad masses of farmers, and is suitable for developing green and healthy breeding and producing pollution-free livestock products.

Description

technical field [0001] The invention relates to a compound premix for pigs, which belongs to the field of 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. Microecological preparation is a kind of green and safe feed additive that has been researched more at present. This kind of preparation is produced by industrial fermentation of animal beneficial bacteria, and contains live bacterial preparations composed of many beneficial microorganisms and their metabolites. But at present, the probiotics used for premixes on the market have the main quality problems in the following aspects: (1) the type of strain is single; (2) the content of viable bacteria is ...
