Antibiotic-free large pig feed and preparation method thereof

Abstract

The invention discloses an antibiotic-free large pig feed and a preparation method thereof. The feed comprises the following raw materials in parts by weight: 60-65 parts of corn, 20-25 parts of soybean meal, 3-5 parts of bran, 8-12 parts of full-fat rice bran, 4-6 parts of a mixture of rice bran and rice hulls, 2-4 parts of an acidulant, 0.3-0.4 part of table salt, 1-1.5 parts of stone powder, 0.3-0.6 part of dicalcium phosphate, 0.5-1.5 parts of amino acids, 0.05-0.1 part of choline chloride, 0.03-0.04 part of a vitamin premix agent, 0.05-0.15 part of an organic mineral premix agent, 0.001-0.005 part of a compound enzyme preparation, 0.02-0.05 part of high temperature resistant phytase, 0.01 part of antimicrobial peptides, 0.1-0.2 part of yeast cell walls, 0.01-0.03 part of an antioxidant, 0.02-0.05 part of a mildewproof agent and 0.02-0.1 part of zeolite powder. Through the adoption of the antibiotic-free large pig feed and the preparation method thereof disclosed by the invention, the serious problem that health is possibly damaged due to drug residues, drug tolerance and the like of pork caused by the addition of antibiotics to the feed can be solved, the immunity of the pigs can be improved, the risk that the animals suffer from diseases is reduced, the purposes that the pigs are well bred when the pigs are free from diseases and the pigs suffering from the diseases can be well treated can be achieved, and the production properties and the meat quality of the pigs can also be improved.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to an antibiotic-free pig feed and a preparation method thereof. Background technique [0002] After the reform and opening up, my country's feed industry has developed rapidly and achieved huge economic benefits. At the same time, it is also facing problems such as antibiotic residues and excessive heavy metals that endanger people's health. Because antibiotics have good antibacterial properties and growth-promoting properties, they have been added in different doses in feed. However, antibiotics can cause bacteria to develop drug resistance, and the dose of their effect is increasing with the increase of the service life, which leads to the gradual enhancement of bacterial drug resistance, forming a vicious circle. At the same time, the use of high-dose antibiotics The addition also led to the increase of antibiotic residues in the environment and in animal produc...
