Antimicrobial-free feed for growing pigs, and its preparation method

Abstract

The invention discloses an antimicrobial-free feed for growing pigs. The antimicrobial-free feed comprises 45-65wt% of corn, 15-25wt% of soybean meal, 1-3wt% of chyle fat, 5-15wt% of wheat bran, 0.2-0.3wt% of a mineral matter premix, 0.02-0.03wt% of a vitamin premix, 0.1-0.2wt% of calcium hydrogen phosphate, 0.1-0.5wt% of stone flour, 0.1-0.2wt% of amino acid, 0.1-0.4wt% of salt, 0.03-0.05wt% of Radix Codonopsis, 0.03-0.08wt% of Radix Astragali, 0.03-0.08wt% of Rhizoma Atractylodis Macrocephalae, 0.03-0.08wt% of dry ginger, 0.03-0.1wt% of Poria cocos, 0.01-0.02wt% of tea tree oil and 0.02-0.04wt% of Fructus Rosae Laevigatae. A preparation method of the antimicrobial-free feed concretely comprises the following steps: receiving, cleaning, metering, crushing, burdening, mixing, granulating, carrying out classified screening, adding a liquid, packaging, and storing. The antimicrobial-free feed has the advantages of enhancement of the nonspecific immune functions of weaned piglets, substantial improvement of the immune effects of swine fever vaccines, improvement of the weight gain, and reduction of the feed conversion rate.

Description

technical field [0001] The invention relates to an antibiotic-free feed for growing 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 and humans.

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
