Feed for promoting growth and weight gain of pigs and preparation method thereof

Abstract

The invention discloses a feed for promoting growth and weight gain of pigs and a preparation method thereof. The feed is prepared from the following raw materials in parts by weight: 150-160 parts of wheat bran, 60-70 parts of rice bran, 10-15 parts of malt roots, 24-28 parts of cottonseed meal, 10-14 parts of vinasse, 8-10 parts of grifola frondosa, 10-12 parts of lychee seed powder, 18-20 parts of dried sweet potato, 6-8 parts of lotus stem, 7-9 parts of purple lythrum herb, 9-11 parts of Indian rorippa herb, 6-10 parts of radix puerariae vine, 3-5 parts of garlic, 5-7 parts of fructus aurantii, 6-8 parts of cortex fraxini, 8-10 parts of liquorice roots, 6-7 parts of acanthopanax bark, 4-6 parts of shell powder, 14-15 parts of soybean oil, 2-3 parts of salt, 2-4 parts of calcium hydrogen phosphate, 0.5-0.7 part of ferrous fumarate and 6-8 parts of nutrition additives. the components of the feed provided by the invention are reasonably matched to meet the requirements of pigs on organic acids, nutrients and special materials, and can be used for promoting the metabolism of the pigs so as to promote the growth and development the pigs, moreover, the added traditional Chinese medicine components have the functions of resisting bacteria and viruses, enhancing immunity, diminishing inflammation and clearing heat, so that the resistance of the pigs to bacteria and viruses is reinforced, and the immunity of the pigs is improved.

Description

technical field [0001] The invention relates to a feed, in particular to a feed for promoting growth and weight gain of pigs and a preparation method thereof. Background technique [0002] With the development of animal husbandry and the improvement of people's living standards, people's demand for animal food has changed from light weight to heavy weight, and there are higher requirements for drug residues and hygienic quality. However, in order to make pigs grow faster and reduce the cost of pig breeding, farmers add antibiotics and chemical agents to feed in large quantities for a long time. Long-term use of these substances will not only easily lead to drug resistance of pathogenic microorganisms, decline in animal immunity and product quality. Food safety problems caused by the residues of these substances in livestock and poultry meat, milk, eggs and edible offal, as well as the transfer of bacterial resistance in animals to human pathogenic bacteria caused by antibiot...

However, in order to make pigs grow faster and reduce the cost of pig breeding, farmers add antibiotics and chemical agents to feed in large quantities for a long time. Long-term use of these substances will not only easily lead to drug resistance of pathogenic microorganisms, decline in animal immunity and product quality. Food safety problems caused by the residues of these substances in livestock and poultry meat, milk, eggs and edible offal, as well as the transfer of bacterial resistance in animals to human pathogenic bacteria caused by antibiotics, have aroused people's high Pay attention to
