Embodiment 1

[0028]Carnosine, yucca extract, creatine monohydrate, α-lipoic acid and defatted rice bran are pulverized and passed through an 80-mesh sieve for later use. After mixing 2 parts by weight of carnosine and 2 parts by weight of yucca extract with 71 parts by weight of defatted rice bran, add 20 parts by weight of creatine monohydrate and 5 parts by weight of α-lipoic acid to continue mixing to obtain a feed additive . Wherein, the yucca extract is the first reflux extraction of yucca with ethanol, and the extract after the first reflux extraction is concentrated; the extract is extracted with water and n-butanol, and the n-butanol extraction phase is collected and dried. ; Finally, ether is used to carry out the second reflux extraction of the above-mentioned n-butanol extraction phase, and the ether-insoluble matter is collected. The above-mentioned feed additive is added to the feed for fattening pigs at 1% by weight.

Embodiment 2

[0030] Carnosine, yucca extract, creatine monohydrate, α-lipoic acid and defatted rice bran are pulverized and passed through an 80-mesh sieve for later use. Then after the carnosine of 4 weight parts and the yucca extract of 4 weight parts are mixed with the defatted rice bran of 57 weight parts, then add the creatine monohydrate of 25 weight parts and the α-lipoic acid of 10 weight parts and continue to mix, obtain feed additive. Wherein, the yucca extract is the first reflux extraction of yucca with ethanol, and the extract after the first reflux extraction is concentrated; the extract is extracted with water and n-butanol, and the n-butanol extraction phase is collected and dried. ; Finally, ether is used to carry out the second reflux extraction of the above-mentioned n-butanol extraction phase, and the ether-insoluble matter is collected. The above-mentioned feed additive is added to the feed for fattening pigs at 1% by weight.

Embodiment 3

[0032] Carnosine, yucca extract, creatine monohydrate, α-lipoic acid and defatted rice bran are pulverized and passed through an 80-mesh sieve for later use. Then after the carnosine of 6 parts by weight and the Yucca extract of 6 parts by weight are mixed with the defatted rice bran of 43 parts by weight, then add the creatine monohydrate of 30 parts by weight and the α-lipoic acid of 15 parts by weight and continue to mix, obtain feed additive. Wherein, the yucca extract is the first reflux extraction of yucca with ethanol, and the extract after the first reflux extraction is concentrated; the extract is extracted with water and n-butanol, and the n-butanol extraction phase is collected and dried. ; Finally, ether is used to carry out the second reflux extraction of the above-mentioned n-butanol extraction phase, and the ether-insoluble matter is collected. The above-mentioned feed additive is added to the feed for fattening pigs at 1% by weight.

Abstract

The present invention relates to a meat quality improving feed additive for fattening pigs and a preparation method and an application thereof, and belongs to the field of feed. The feed additive comprises 20-40 parts by weight of creatine monohydrate, 5-25 parts by weight of alpha-lipoic acid, 2-10 parts by weight of carnosine, 2-10 parts by weight of yucca extract and 15-71 parts by weight of carriers. The preparation method comprises the following steps: the carnosine, yuccan extract and carriers are mixed, then the creatine monohydrate and alpha-lipoic acid are added, and the materials are continuously mixed to obtain the finished products. The preparation method is simple and the preparation condition is good in controllability. The prepared feed additive by the method can slow down pH of muscles of the fattening pigs, increases water holding capacity of the muscles, improves meat color and tenderness, can be applied in the feed for the fattening pigs, can significantly improve the meat quality and flavor of the fattening pigs, at the same time improves antioxidant capacity of the fattening pig body and reduces ammonia nitrogen emission.

Description

technical field [0001] The invention relates to the field of feed, and in particular to a feed additive for improving the quality of fattening pork, a preparation method and application thereof. Background technique [0002] my country is a large pork production and consumption country. For many years, the pig industry has greatly improved the growth rate and feed utilization rate of pigs through genetic breeding, nutritional improvement, environmental control and other measures, but the quality of pork has declined significantly. However, with the improvement of living standards, people pay more and more attention to the safety, quality and flavor of pork. [0003] Due to the high content of muscle glycogen during slaughter, the glycolysis of sugar increases the production of lactic acid, thereby accelerating the pH drop, which will lead to the production of PSE meat; after slaughter, a large number of lipid peroxides in the muscle undergo oxidation reactions, destroying th...
