Technical Field

The invention relates to a compound lactobacillus fermented feed, and belongs to the technical field of feed production in the pig industry.

Background

Lactic acid bacteria are widely present in intestinal tracts of people, livestock and poultry, the capability of fermenting carbohydrate is strong, and the lactobacillus plantarum, the lactobacillus bifidus, the lactobacillus acidophilus and the like are widely applied to feeds at present. The research shows that the lactobacillus fermented feed can improve the palatability and the utilization rate of the feed, improve the micro-ecological environment, improve the disease resistance of organisms, promote the growth of animals, improve the quality of pork and have obvious economic benefit.

The lactobacillus has strong fermentation capacity and low requirement on culture environment, can ferment common grains or industrial byproducts such as soybean meal, corn, bran, pomace, beer residue, sugar residue and the like, generates various digestive enzymes such as amylase, lipase, protease and the like, and is beneficial to digestion and absorption of the feed. Influence of the lactobacillus fermented feed on the production performance of growing pigs [ J ] grain and feed industry, 2010 (3): 37-40) the economic benefit is improved by 22.7-31.6% when the weaned piglets are fed after the air-dried lactobacillus fermented feed and basic ration in different proportions are mixed. Zhangyu and the like (Zhangyu, Shichangyou, Wangcheng, and the like. study on improving the nutritive value of corn-soybean meal type feed by bacterium-enzyme synergistic fermentation [ J ]. Chinese food and oil academy, 2018, 33 (3): 70-77) lactobacillus, saccharomycetes, bacillus subtilis and a complex enzyme preparation are inoculated in the composite feed for fermentation for 72 hours, so that the feed intake and daily gain of piglets can be improved, the growth performance of the piglets can be improved, and the use of feed antibiotics can be reduced. The research on the influence of the fermented feed on the production performance and fecal microorganisms of sows and suckling piglets [ J ] swine industry science, 2018, 35 (7): 88-91) finds that the lactation yield of sows and the weaning weight of suckling piglets can be obviously improved when the fermented feed is separately fed in the later gestation period and the lactation period, and the effect of improving the lactation yield of the sows and the growth performance of the suckling piglets by feeding the fermented feed in 2 periods is better.

The lactobacillus fermented feed is mature in scientific research, but the problems that how to standardize the use of the lactobacillus, how to perfect the fermentation process and how to carry out large-scale production are urgently needed to be solved in the production practice are solved at present.
