Problems solved by technology

In recent years, a large number of studies have shown that the addition of selenium in the diet of finishing pigs can significantly improve the quality of pork and increase the content of selenium in the muscle, but most of them are mainly inorganic selenium, and the utilization efficiency of selenium is not high. Based on this, it is necessary to provide a This kind of feed can improve the quality of pork, and at the same time can provide enough selenium, and increase the deposition of selenium in pork to meet people's dual needs for taste and mineral elements

Abstract

The invention provides selenium-rich feed capable of improving pork quality. The selenium-rich feed is prepared from the following components in parts by weight: 400-600 parts of corn, 50-250 parts ofsorghum, 50-200 parts of bean meal, 0-200 parts of wheat bran, 0-150 parts of soybean hull, 5-10 parts of calcium hydrogen phosphate, 5-15 parts of stone powder, 0.5-5 parts of lysine hydrochloride,0.5-1.2 parts of choline chloride, 2-5 parts of table salt, 2-5 parts of a selenium-rich supplement and 10 parts of a premix. The selenium-rich feed capable of improving pork quality fully considers the digestion physiologic characteristics of fattening pigs in treatment and selection of raw materials, meets the nutritional needs of the fattening pigs and ensures the feed efficiency and palatability, and the selenium supplement contains organic selenium and other nutrient substances capable of improving meat quality, has good absorption rate, can obviously improve the pork quality and improvesthe selenium content in muscles.

Description

technical field [0001] The invention belongs to the field of feed and relates to a selenium-enriched feed for improving pork quality. Background technique [0002] With the improvement of people's living standards, consumers have higher and higher requirements for meat quality. Pork must not only be clean and hygienic, but also have a better taste. In addition, market operations require pork to have a longer shelf life, which means that while the competition in the pork market is becoming increasingly fierce, it is necessary to continuously improve the quality of meat in order to meet the high requirements of customers and sellers. Generally speaking, pork quality mainly includes several aspects such as pH, meat color, tenderness, drip loss, intramuscular fat content, fatty acid composition and flavor, and is affected by factors such as genetics, environment, nutrition, transportation and slaughtering treatment. A series of practices have shown that these qualities of pork ...
