Compound premixed feed for improving pork quality of fattening pigs

Abstract

The invention discloses compound premixed feed for improving pork quality of fattening pigs. The compound premixed feed is prepared from the following components in parts by weight: 150-200 parts of dicalcium phosphate, 275-305 parts of stone powder, 75-100 parts of sodium chloride, 25-50 parts of lysine, 22-25 parts of premixed feed, 3-5 parts of phytase, 283-336 parts of zeolite powder, 12-16 parts of Jinduowei SP500A, 15-25 parts of a compound micro-ecological premixed agent, 5-10 parts of vitamin E, 5-10 parts of vitamin C and 10-20 parts of calcium propionate, wherein the sum of the quality of all components is 1000. The compound premixed feed disclosed by the invention is capable of enhancing the feed stability, enhancing the production performance of the pigs, overcoming the defects of common trace elements, enhancing the oxidation resistance of the pigs, obviously improving the pork quality and greatly reducing heavy metal residues in pork.

Description

technical field [0001] The invention belongs to the technical field of animal feed and relates to a compound premixed feed for fattening pigs which improves the quality of pork. Background technique [0002] At present, with the rapid development of my country's breeding industry and the improvement of living standards, people are paying more and more attention to dietary health. The demand for meat products has changed from the demand for meat products in the 1980s and 1990s to the demand for meat quality in recent years. Factors affecting pork quality mainly include genetic factors, feed nutrition factors, and feeding management factors. We know that once the pig breed is determined, its meat quality is difficult to change unless it can be achieved through a long-term genetic improvement process. In actual production , Feed nutrition is the most direct factor affecting pork quality. Especially the fattening stage is more critical, and the feed during this period is partic...

Problems solved by technology

[0005] Every feed factory will add trace elements to the feed to improve the performance of pigs and improve the health of pigs. However, sometimes in order to cater to the market or the preferences of farmers, a large amount of trace elements are added to the feed, especially high copper and high zinc. It is more widely used and can make the pig manure black and the skin red and shiny, but high copper will make the pork fat soft, accelerate fat oxidation, produce bad smell, cause yellow fat meat, and cause especially nutrients in the feed is the destruction of vitamins

At the same time, adding high copper will cause the copper in pig liver to increase by 2-3 times, which will affect the liver function of pigs, and people will appear poisoning symptoms after eating

Excessive trace elements will be excreted with feces, causing environmental pollution

[0006] Commonly used trace element additives are sulfates. Many products are unstable, have many impurities, are easy to absorb moisture and deteriorate, and some have strong oxidative properties, which can cause corrosion to the gastrointestinal mucosa of animals and destroy nutrients in the feed. Such as vitamins, fats, enzyme preparations and microecological preparations, etc., reduce the quality of feed

Especially the content of heavy metal elements in the trace elements of some unscrupulous manufacturers exceeds the standard, and some feed factories add excessive amounts, which will inevitably increase the content of heavy metal elements in the feed, which will adversely affect the growth and health of the animals themselves. At the same time, the residue of heavy metal elements in meat will increase. , reducing pork quality
