Embodiment 1

[0024] A kind of selenium-enriched lactic acid bacteria biological feed additive of the embodiment of the present invention is prepared from the following raw materials in mass percentage: rice bran (provided by Longyu Company, Hunchun City) 87%, lactic acid bacteria (provided by the animal nutrition laboratory of Yanbian University College of Agriculture) 10% , Sodium Selenite 3%. The specific preparation method is as follows: firstly weigh the raw materials according to the mass percentage of the raw materials, then sterilize the weighed rice bran and pack it into a tank, then add lactic acid bacteria and sodium selenite and mix well, and carry out anaerobic fermentation. The temperature of the anaerobic fermentation is 35°C, the fermentation time is 60 hours. After the fermentation is completed, low-temperature drying is carried out, and the low-temperature drying is dried in a drying oven. The temperature is controlled at 55°C to 65°C, and the time is 48h to 60h. After dr...

Abstract

The present invention discloses a selenium-enriched lactic acid bacterium biological feed additive which is prepared from the following raw materials in mass percentages: 80-90% of rice bran, 7-15% of lactic acid bacteria, and 2-5% of sodium selenite. The preparation method is as follows: firstly the raw materials are weighed according to the raw material mass percentage, then rice bran is sterilized and canned, the lactic acid bacteria and the sodium selenite are added into the canned rice bran and mixed evenly, and the mixture is subjected to an anaerobic fermentation, the fermented mixture is dried at a low temperature, and then the dried mixture is pulverized and prepared into the selenium-enriched lactic acid bacterium biological feed additive. The selenium-enriched lactic acid bacterium biological feed additive can improve the gastrointestinal tract environment, increase beneficial bacterium flora, promote gastrointestinal digestion and absorption, reduce diarrhea, improve animal immunity, especially reduce the morbidity and mortality of piglets, and bring larger economic benefits to farmers.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation, and in particular relates to a selenium-enriched lactic acid bacteria biological feed additive and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, the demand for meat is increasing day by day, and the voice of green food is getting higher and higher. However, in pig breeding, in order to shorten the breeding cycle, reduce mortality, and reduce costs, most farmers will choose to add antibiotics, antibacterial drugs and other drugs to the feed, resulting in the emergence of drug resistance or drug resistance in pigs. Reduced function, decreased disease resistance, and antibiotic residues in pork. And in breeding process, if do not use medicines such as antibiotics, be unfavorable for its growth again for piglet, make the phenomenon that piglet is easy to die happens from time to time. [0003] With the ...
