Antibiotic-free feed for second stage of fattening pigs and preparation method thereof

Abstract

The invention discloses antiboitic-free feed for the second stage of fattening pigs. The feed is prepared according to the formula containing the following components in parts by weight: 45-65% of corn, 13-20% of soybean meal, 8-15% of bran, 0.2-0.3% of mineral premixed agents, 0.02-0.03% of vitamin premixed agents, 0.1-0.2% of calcium hydrogen phosphate, 0.1-0.5% of stone powder, 0.1-0.4% of table salt, 0.2-0.35% of epimediums, 0.1-0.3% of eucommia ulmoides, 0.05-0.08% of star anise, 0.1-0.2% of dried ginger, 0.05-0.08% of rhodiola roots, 0.1-0.3% of radix fici simplicissimae, 0.05-0.08% of uncaria, 0.1-0.15% of senna obtusifolia, 0.03-0.05% of orange peel, 0.15-0.2% of astragalus membranaceus, 0.1-0.2% of codonopsis pilosula, 0.05-0.08% of licorice roots, and 0.005-0.02% of tea tree oil. The preparation method of the antibiotic-free feed for the second stage of the fattening pigs comprises the following specific steps of receiving, cleaning, metering, crushing, mixing ingredients according to a recipe, mixing, pelletizing, sieving with classifying screens, adding liquid, and packaging for storing. The feed disclosed by the invention solves the problems of drug remaining, drug tolerance and environmental pollution due to antibiotics added in the feed. In addition, with the feed in which Chinese herbal medicine is added in comparison with traditional feed, the immunity of pigs can be improved, the disease attack risk of animals is reduced, and at the same time, the special flavor of pork products can be improved.

Description

technical field [0001] The invention relates to a second-stage antibiotic-free feed for fattening pigs and a preparation method thereof, belonging to the field of feed products. Background technique [0002] Since aureomycin was approved by the US FDA as a feed additive in the 1950s, dozens of antibiotics have been approved as growth promoters for animals, which has largely promoted the intensification of animal husbandry, and brought huge economic benefits. Therefore, in order to improve the economic benefits of livestock and poultry farming, antibiotics in the livestock and poultry industry have been widely used and abused in the production of livestock and poultry feed. However, the long-term use of antibiotic additives in animals has brought many adverse consequences, the most important of which is the continuous increase in the number and types of drug-resistant bacteria in animals, and the resistance of bacteria will also be transmitted horizontally between animals an...

AI Technical Summary

Problems solved by technology

Another major consequence of using antibiotics in animals is that the resistance of animals is significantly reduced, and the risk of various infectious diseases is greatly increased

In addition, due to the fact that modern animal husbandry is largely one-sided pursuit of production performance, while ignoring product quality

Although the application of antibiotics has improved the growth rate of animals and the utilization efficiency of feed, it has seriously affected the flavor and quality of meat products
