A kind of production method of Licha black pig high-quality pork

Abstract

The invention provides a method for producing high-quality pork from Licha black pigs. According to the method, the growth and development of Licha black pigs are divided into three stages according to their weight, and different amino acid models are set according to different development stages. Under the premise of not increasing the feeding cost, the production method can meet the nutritional needs of Licha black pigs for growth and development, promote the growth potential of Licha black pigs, effectively increase the lean meat percentage of Licha black pigs, and improve the intermuscular fat content of pigs , improve meat production and pork evaluation scores, and increase breeding benefits; at the same time, effectively reduce the amount of protein raw materials (such as soybeans), improve the growth performance and health level of Licha black pigs, reduce the nitrogen emission of Licha black pigs, and reduce the Environmental pollution caused by feeding Licha black pigs.

Description

technical field [0001] The invention belongs to the technical field of breeding industry, and in particular relates to a method for producing high-quality pork from Licha black pigs. Background technique [0002] Licha black pig is an excellent local pig breed in Shandong Province. It has the characteristics of strong resistance, not easy to be infected with infectious diseases and good meat quality. With the rapid development of scale and standardization of the pig farming industry, the breeding scale of Licha black pigs is also increasing. The disadvantages of Licha black pigs are low protein, amino acid and phosphorus metabolism, poor fattening ability and carcass performance, slow weight gain, late body maturity, low feed remuneration, small skin thickness, fat thickness, eye muscle area and hind leg ratio , The lean meat rate is low. At the same time, it is worth noting that the development of the animal husbandry industry has also caused serious pollution to the env...

Problems solved by technology

The disadvantages of Licha black pigs are low protein, amino acid and phosphorus metabolism, poor fattening ability and carcass performance, slow weight gain, late body maturity, low feed remuneration, small skin thickness, fat thickness, eye muscle area and hind leg ratio , low lean meat

At the same time, it is worth noting that the development of the animal husbandry industry has also caused serious pollution to the environment. According to estimates, each pig in the pig industry produces an average of 2.5 tons of feces and urine per year, and a farm of 10,000 pigs discharges feces to the surrounding environment at least every year. 30,000 tons, the daily sewage volume is 100-150 tons, and there are more than 200 kinds of fecal odor components; and due to the above-mentioned shortcomings of Licha black pigs, raising Licha black pigs will cause more serious environmental pollution. However, how to improve Licha black pigs There is no unified standard for the production method of high-quality pork
