Abstract

The invention discloses a breeding method for reducing heavy metal and antibiotics residues in meat of conventional semi-free black pigs. According to the breeding method, in a process of breeding live pigs, only natural beneficial bio-preparations are added into the conventional feed; the dietary structure of the live pigs is thoroughly changed by adding organic substances such as amino acid substances and mineral substances, so that environment-friendly and green meat food is realized from the feed for the pigs; the organic substances can be used for removing hormone, toxins and heavy metals, which are harmful to a human body, in pig bodies; an experimental test shows that due to an ecological daily ration formula, by reasonable application of organic trace elements, the heavy metals and antibiotics in pork are completely removed; furthermore, the safety coefficient of the pork is greatly increased; more amino acid substrates and mineral substances are added, so that the pork tastes more delicious, and the nutritional value is higher; therefore the quality of the produced pork is higher; the pork is rich in eight amino acids, and the content of the eight main amino acids is larger than the content of the amino acids in the conventional wild pork; the pork of the black pigs bred by the breeding method is high in protein and low in fact, does not contain cholesterol, and has a good health-protection function.

Description

technical field [0001] The invention belongs to the technical field of breeding methods for special pigs, and in particular relates to a breeding method for reducing the residue of heavy metal antibiotics in the quality of semi-free-range traditional black pork. Background technique [0002] In order to maximize the production performance of livestock and poultry, livestock and poultry breeders and feed producers often intentionally increase trace elements such as copper, zinc, and iron in feed preparation. Copper, zinc, and iron and other trace elements are essential nutrients for pig growth and development Components, and large doses of copper, zinc, etc. can significantly promote the growth rate of pigs, make the pigskin red and shiny, and look extraordinary. Excessive addition of such elements in feed has become a means for some feed manufacturers to compete for the market. Not paying attention to the enrichment of mineral elements, trace elements and toxic and harmful s...
