Abstract

The invention discloses a preparation method and an application method of feeding lactobacillus preparation capable of improving quality and flavor of pork. One lactobacillus or a plurality of lactobacilli including lactobacillus plantarum and lactobacillus fermentum are subjected to complex static fermentation or independent fermentation to obtain liquid bacteria and dry powdery bacteria; the liquid bacteria is added to drinking water for the pig according to the proportion of 5 / 10000 to 2 / 100 and the dry powdery bacteria is added to the feed according to the proportion of 5 / 10000 to 2 / 100 so that the two live bacteria can enter the intestine of the pig to affect the digestion and the metabolism of the pig. The feeding lactobacillus preparation needs to be fed to the pig of 50 kg or less for at least over 45 consecutive days before the pig is slaughtered so that the immunity of the pig is improved, less or no antibiotic is fed to the pig, no medicinal residue is found in the pork, and the pork is obviously fresh and sweet and is obviously different from the current common pork on the market in flavor.

Description

technical field [0001] The invention relates to the technical field of biological products, and more specifically relates to the application of microbial technology in animal breeding. Background technique [0002] The development of modern animal husbandry has greatly improved the growth efficiency of the pig industry through the technological progress of genetic breeding, disease control, and nutritional feeding. From the traditional annual growth period to the current 150 days, it has reached more than 100 kg, and the feed ratio has developed from 5:1. Today's 2.8:1 or so. In most countries, the state of scarce pork supply has been eliminated, and a problem of supply quantity has been solved. But the yield is high, the growth cycle is short, the taste is bad, there are too many medicines and drug residues, it is unsafe to eat pork, and the quality has declined. This problem is particularly prominent in China. [0003] In order to solve the problem of drug residues, gov...
