Microbial fermentation pig feed

Abstract

The invention discloses microbial fermentation pig feed. The microbial fermentation pig feed comprises, by weight, 1-5 parts of compound bacteria liquid, 10-15 parts of bean cakes, 2-2.5 parts of bran, 60-70 parts of corn powder, 4-5 parts of cane sugar and 10-20 parts of water, wherein the compound bacteria liquid comprises compound bacteria, a compound bacteria cultivation medium and appropriate amount of nutritive salt, and the weight ration of the compound bacteria to the compound bacteria cultivation medium is 5-10:100. The compound bacteria comprises, by weight, 5-10 parts of bacillus licheniformis, 10-15 parts of bacillus subtillis, 30-35 parts of lactobacillus plantarum, 40-44 parts of streptococcus lactis and 1-5 parts of saccharomyces cerevisiae. The compound bacteria cultivation medium comprises, by weight percentage, 2-2.5% of cane sugar, 0.5-1% of peptone, 0.02-0.05% of urea, 0.1-0.3% of sodium chloride, 0.01-0.03% of magnesium sulfate, 0.5-1.5% of Vitamin B1 and the balance being water. According to the microbial fermentation pig feed, the pig feed is easy to absorb and use after being composited with fermentation of beneficial microorganisms, and therefore the growth speed and the out-of-fence speed of commercial pigs are fast; the muscle water-dropping loss is reduced, and the lean meat percentage, the cooked meat rate and the total content of muscle crude protein and amino acid are improved.

Description

technical field [0001] The invention relates to pig feed, in particular to a microbial fermented pig feed. Background technique [0002] Since the 1950s, the addition of antibiotics to animal rations has significantly boosted animal production and contributed significantly to the development of intensive animal husbandry. However, with the passage of time, due to the long-term continuous use of antibiotics in livestock and poultry feed in the past, animal resistance has been caused, and pathogenic bacteria harmful to humans have developed resistance, which in turn affects human public health and safety. In recent years, the continuous emergence of drug-resistant pathogenic bacteria in human medical treatment has attracted great attention from public health departments all over the world, and corresponding measures have been taken to prevent them. As early as 1999, EU countries reduced the types of medicated feed additives to 4, and on January 1, 2006, the use of non-therape...
