Antibiotic-free feed for the first phase of pig fattening and preparation method thereof

Abstract

The present invention discloses an antibiotic-free feed for the first phase of pig fattening, and the feed comprises the following ingredients, by weight, 46-65% of corn, 13-20% of soybean meal, 0-10% of fish meal, 5-15% of bran, 0.2-0.3% of a mineral premix, 0.02-0.03% of a vitamin premix, 0.1-0.2% of calcium hydrogen phosphate, 0.1-0.5% of stone powder, 0.1-0.4% of salt, 0.03-0.05% of codonopsis pilosula, 0.03-0.08% of astragalus membranaceus, 0.03-0.08% of atractylodes macrocephala, 0.03-0.08% of dried ginger, 0.03-0.1% of poria cocos, 0.01-0.02% of tea tree oil and 0.02-0.04% of rosa laevigata. The preparation method for the antibiotic-free feed includes the following steps: receiving, cleaning, measuring, crushing, material preparing, mixing, pelletizing, grading screening, liquid adding, packaging and storing. With the feed, the problems of drug residue, drug resistance and environmental pollution which are caused by addition of antibiotics to the feed can be solved. In addition, compared to the conventional feed, the feed into which the Chinese herbals are added has the beneficial effects of enhancing the pig immunity, reducing the incidence risk, and improving the pork product flavor.

Description

technical field [0001] The invention relates to a first-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
