Abstract

The invention discloses a feed for medium pigs. The feed consists of the following raw materials in parts by weight of 50-60 parts of corn, 9-12 parts of wheat bran, 16-25 parts of soybean meal, 4-8 parts of rice bran, 4-8 parts of middling, 1-4 parts of bone meal and 2-5 parts of a Chinese herbal medicine preparation, wherein the Chinese herbal medicine preparation consists of the following raw materials in parts by weight: 8-15 parts of radix angelicae sinensis, 5-10 parts of radix astragali, 6-12 parts of Chinese yams and 1-5 parts of radix codonopsis. After the feed for medium pigs is fedto the pigs, growth and development are quick, the adaptability is good, the healthy growth of the medium pigs can be promoted, and the quality of pork can be improved; in the growth process of the medium pigs, the survival rate of the medium pigs is high, the situation that the medium pigs are thin, do not become fat, generate swine infuenza or streptococcal disease cannot appear, and the growthand fattening effects at a later stage are not influenced; and the feed is free from antibiotics and is low in production cost.

Problems solved by technology

[0003] Feed is extremely critical for the growth of medium-sized pigs. Considering the prevention and control of diseases during the growth of medium-sized pigs in the prior art, some feed additives have appeared, but these product additions are mainly hormone drugs or other additives, such as Antibiotics, hormones, high copper, clenbuterol, and arsenic additives, etc., have solved some problems in the short term, but in fact lead to a sharp decline in pork quality, and more importantly, they will cause great harm to human health; In addition, the growth of medium-sized pigs is the most important part in the growth process of live pigs, and it is easy for medium-sized pigs to lose weight and not grow meat, swine flu or streptococcal disease
