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 microbial preparations, its application effect on animals is limited

Embodiment 2

[0046] Embodiment 2, the preparation of compound probiotics

[0047] 1. Preparation of Bacillus licheniformis CGMCC No.5094 bacterial powder

[0048] 1) Plate culture rejuvenation: Inoculate the Bacillus licheniformis strain on the BPY plate medium, culture at 37°C for 24 hours, rejuvenate the Bacillus licheniformis, and form a single colony, pick a single colony and inoculate it on the slant medium, Incubate at 37°C for 36 hours;

[0049] 2) Preparation of first-class seeds: transfer the Bacillus licheniformis cultured in step 1) to eggplant bottle slant medium, and cultivate them at 37° C. for 12 hours to make them in the late logarithmic period to obtain first-class seeds;

[0050] Described slant medium is BPY solid medium;

[0051] 3) Preparation of secondary seeds: make bacterial suspension from the primary seeds prepared in step 2) with sterile water, and inoculate into 1.6M 3 2M of BPY seed medium 3 In the seed tank, the temperature is 37°C, the rotation speed is 2...

Abstract

Belonging to the premix field, the invention provides a compound premix able to improve the immune function for pigs. The premix mainly comprises: ferrous sulfate, copper sulfate, zinc sulfate, manganese sulfate, potassium iodide, cobalt chloride, sodium selenite, organic trace elements, multiple vitamins, pantothenic acid, nicotinic acid, folic acid, biotin, lysine, a compound microecological preparation, ethoxy quinoline, 50% of choline chloride, zeolite powder and wheat bran. Without any antibiotic, the premix of the invention has a rational formula, contains a variety of probiotics and isof high live bacteria content. Animal feeding experiments prove that the premix has ideal feeding effects of high pig survival rate, fast weight gain and improved feed conversion efficiency. Being conducive to improve the intestinal microenvironment of pigs, maintain intestinal health, improve the immune function of pigs, reduce the occurrence of diseases and promote pig growth, the premix provided in the invention can satisfy the demands of vast raising households, and is suitable for developing green and healthy breeding as well as producing pollution-free livestock products.

Description

technical field [0001] The invention relates to a compound premix for pigs capable of improving immune function, belonging to the field of premix. Background technique [0002] At present, there are many types of domestic premixes, but most of them are added with antibiotics. The negative problems brought about by the long-term and large-scale application of antibiotics in animals have gradually been paid attention to by people. Probiotics are recognized as a class of green and safe feed additives. These preparations are produced by industrial fermentation of beneficial animal bacteria, and contain live bacterial preparations composed of many beneficial microorganisms and their metabolites. 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) intolerance to antibiotics; (4) poor str...
