Abstract
The invention relates to a feed additive for slowly decreasing adverse effect on pork quality caused by transportation and slaughtering stress; the feed additive comprises magnesium aspartate, magnesium sulfate, calcium chloride, calcium propionate, organic selenium, vitamin E, glucose, sodium bicarbonate and potassium bicarbonate. The feed additive adopts a nutrition method to slowly decrease the pork quality caused by transportation and slaughtering stress, the main nutrition addition ingredients choose essential nutrition ingredients which can effectively regulate a pig organism oxidation and antioxidant balance system, a neuroendocrine system, a glycometabolism system and an acid base balance system, the stress can be slowly decreased effectively, the incidence rate of low-quality pork is reduced, and the pork quality is improved. By adding the feed additive at different weight phases of growing-finishing pigs, the incidence rate of low-quality pork is obviously lower than that of a group which is not added with the feed additive, and the pork quality is obviously higher than that of the group which is not added with the feed additive, thereby greatly improving the economic benefit of raising farms and packinghouses.
Description
Technical field
The present invention relates to a kind ofly extenuate transportation and butcher the feed addictive that stress have a negative impact to meat quality.
Background technology
Because the cultivation of high lean meat percentage kind or strain has brought tangible negative effect to the pork organoleptic quality; Pork inferior such as PSE meat (pale, soft and moisture oozes out), DFD meat (look dark is, hard and dry), yellow fat meat (it is yellow that fat is) and sour pork etc. happen occasionally; Especially in transportation with to butcher under the strong stressed condition incidence higher, cause a large amount of economic losses.Although along with hereditary subject development, eliminated the pig that contains fluothane or sour pork gene in a large number, yet even remove pernicious high temperature (MH) pig through the dna probe detection, in normal pig (not mutated body), meat of poor quality possibly take place still.Research shows that pork quality receives multiple factor affecting such as kind, nutrition, the preceding management of government official, therefore, needs measure to improve pork quality through nutrition, and alleviating transportation and butchering to be feasible to the adverse effect of meat quality.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly extenuates transportation and butchers the feed addictive that stress have a negative impact to meat quality, and this feed addictive can improve and transports and butcher the meat quality under the stressed condition through influence pig body oxidation and anti-oxidant balance sysmte, neuroendocrine system, glycometabolism system and acid-base balance system.
The present invention addresses the above problem the technical scheme that is adopted: a kind ofly extenuate transportation and butcher the feed addictive that stress have a negative impact to meat quality, comprise magnesium aminosuccinate, magnesium sulfate, calcium chloride, calcium propionate, organic selenium, vitamin E, glucose, sodium acid carbonate, saleratus.
Particularly, the mass percent of said magnesium aminosuccinate is 30-50%; The mass percent of magnesium sulfate is 5-10%; The mass percent of calcium chloride is 10-15%; The mass percent of calcium propionate is 8-15%; The mass percent of organic selenium is 1-5%; The mass percent of vitamin E is 1-5%; The mass percent of glucose is 15-20%; The mass percent of sodium acid carbonate is 5-10%; The mass percent of saleratus is 5-10%.
Above-described each nutrient has very important significance for regulation and control pig body oxidation and anti-oxidant balance sysmte, neuroendocrine system, glycometabolism system and acid-base balance system.
Magnesium aminosuccinate and magnesium sulfate: magnesium can suppress the skeletal muscle activity, reduce the secretion of neurotransmitter, suppresses nervimuscular excitability, the content of cortisol and catecholamine in the reduction blood plasma, and effectively alleviating transportation and butcher stress.Simultaneously, magnesium can reduce glycolysis, improves muscle terminal point pH, and increase is a waterpower, reduces the incidence of meat of poor qualities such as PSE.The additive capacity of different magnesium salts, magnesium salts and time all can influence the result of use of magnesium salts.
Calcium chloride and calcium propionate: calcium is mainly regulated the tender degree of pork, and pork endogenous proteinase (mainly being Calpain) in killing post curing process and meat is relevant.Calpain is a kind of Ca-dependent protease; Its activity receives calcium ion concentration and the regulation and control of pH value in the muscle; The calcium ion concentration that Calpain I activation needs is 1-20nmol/L; The calcium ion concentration that Calpain II activation needs is 250-750nmol/L, and the external source calcium ion can influence intracellular calcium concentration.
Organic selenium: pig is high to the absorption and the deposition efficiency of organic selenium; Se content in the musculature is raise, and selenium is the active component of glutathione peroxidase (GPX), mainly is as antioxidant protection muscle cell structural intergrity; Reduce the outflow of cytosol, reduce drip loss.
Vitamin E: as a kind of liposoluble vitamin, the amount retained in muscle increases, and what can obviously improve muscle is waterpower, reduces Ca
2+Burst size and glycolysis speed, can effectively prevent the generation of meat of poor qualities such as PSE.Simultaneously, VE can keep the reducing condition of heme iron, delays the speed and the degree of muscle pigment oxidation, can stablize yellowish pink.
Glucose, sodium acid carbonate, saleratus: as electrolytical main component, can effectively regulate and control the acid-base balance in the pig body under the stressed condition, alleviation stress.
To sum up, the invention has the beneficial effects as follows: the present invention is based on domestic and international progress, is foundation with the achievement that experiment was obtained of fattening pig and fryer, has adopted a kind of trophism means to alleviate transportation and butcher and stress cause meat quality to descend.Prove through all types of experiments; This composite feed additive greatly reduces transportation and butchers the incidence that stress cause meat of poor quality; Improved the color and luster of meat matter, tender degree, improved muscle terminal point pH, increase is a waterpower; Improve the crudy and the shelf life of pork, improved the economic benefit of plant and meat packing plant.
