Pork quality control additive and application thereof

Abstract

A pork quality control additive and application thereof relate to additives and application thereof. The invention solves the problems as follows: the pork quality is decreased under the condition of stress; the cost is high owing to adding organic magnesium to relieve the stress to improve the pork quality. The pork quality control additive comprises magnesium sulfate, magnesium aspartate, zinc sulfate, sodium selenite and a carrier. The additive is applied as follows: adding 1.00-1.50% of the pork quality control additive to the original daily ration fed 7 days before slaughtering pigs according to the weight percent of the original daily ration. The complex additive has low cost and good effect on relieving the stress to improve the pork quality, can relieve the stress on the pigs due to transport and slaughter and can improve the effects on the pork quality due to the stress. The high-dose magnesium can be used as a muscle relaxant and a depressant in the stress states of pigs, can reduce the secretion of catecholamine during slaughtering, reduce the glycogenolysis velocity and glycolysis velocity, improve the pH value of pork and reduce the incidence rate of PSE meat by over 90%.

Description

technical field [0001] The present invention relates to an additive and its application. Background technique [0002] During the period from the breeding farm to the slaughterhouse, pigs have to go through a series of processes such as fasting before slaughter, water deprivation, driving, mixing, getting on, getting off and transporting, and are exposed to noise, strange smell, shaking of the car body , Uneven speed, crowding, unsuitable temperature and unsuitable humidity and other stressors, these stressors will cause behavioral and physiological responses of pigs, and pigs will secrete catecholamines during slaughter, increasing the rate of glycogen decomposition and glycolysis , the pH value of pork decreased, the incidence of PSE meat (refers to the gray-white, soft and oozing muscle of pigs after slaughter) was high, and the quality of pork decreased. [0003] At present, in my country’s pig production, adding organic magnesium (provided by magnesium aspartate) 1500-...
