Compound feed for growing fattening pigs

Abstract

The invention discloses a compound feed for growing fattening pigs. The feed is prepared from the following parts by weight: 70.5 to 76.9 parts of corn, 2 to 5 parts of silkworm chrysalis, 5.3 to 9 parts of 43 soybean meal, 0 to 4 parts of rice bran, 0.44 to 0.65 part of lysine, 0.1 to 0.15 part of threonine, 0.5 to 2 parts of glutamic acid residues, 0 to 1.1 parts of fine stone powder, 0 to 0.5 part of salt, 0.27 to 0.9 part of calcium hydrogen phosphate, 0 to 0.4 part of an acidulant, 0.01 to 0.03 part of an antioxidant, 0 to 0.05 part of aureomycin, 0 to 0.2 part of montmorillonite and 0 to0.02 part of olaquindox. The feed has the following beneficial effects: the high-digestibility and low-antigen protein raw materials are selected, amino acids are balanced, the use of the soybean meal can be reduced, and the ammonia gas emission is reduced; the acidulant and compound plant essential oil can effectively kill gram-negative bacteria and gram-positive bacteria while improving the palatability of the feed; and in the situation of low antibiotic addition, the feed effective resists diarrhea, and improves the utilization rate of proteins, calcium and phosphorus, so that not only theacid-binding capacity of the feed is lowered, but also the palatability is improved.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a compound feed for growing and finishing pigs. Background technique [0002] my country is a large breeding country. The number of pigs on hand is increasing year by year, and people's requirements for raising pigs are also getting higher and higher. How to reasonably formulate feed to achieve balanced nutrition is the basic requirement for feed. In the past pig raising industry, due to the one-sided pursuit of fast growth and good body shape of pigs, people abused clenbuterol hydrochloride (clenbuterol), ractopamine and other prohibited drugs in the pig raising industry, which seriously affected pigs. Human health is damaged, and the export of commercial pork and fresh frozen pork is hindered, making consumers feel insecure about pork. [0003] In recent years, with the increasingly prominent problem of meat food safety, the market has put forward new and higher requiremen...

AI Technical Summary

Problems solved by technology

The current feed for finishing pigs mainly provides nutrition for animals from the perspective of maintenance and growth, but it often cannot meet the market demand. With the significant increase in the production potential of live pigs, the existing feed formula often cannot meet the nutritional requirements of pigs at different growth stages

[0004] How to feed pigs with feeds with different nutritional components according to different growth stages is a problem that traditional feeds have not considered, thus affecting the normal growth of pigs
