Abstract
The present invention discloses a feed capable of increasing pork intramuscular fat and improving meat quality, wherein the feed comprises the following components by mass: 65-75% of corn, 5-20% of soybean meal, 5-10% of wheat bran, 2-7% of rice bran, 0.3-1% of arginine, 0.5-2% of conjugated linoleic acid, 2-7% of alfalfa powder, 1-2% of stone powder, and 1.5-8% of a feed additive. According to the present invention, with the feed, the three-way crossbreeding pig intramuscular fat content can be increased, and the meat quality can be improved.
Description
Technical field
The invention belongs to technical field of animal, be specifically related to a kind of feed improving pork intramuscular fat and improve meat.
Background technology
Along with pig aquaculture large-scale degree and people, the requirement to meat improves constantly, the raising of live pig production performance and the contradiction of meat quality, is difficult to take into account the economic benefit of aquaculture and consumer to the demand of high-quality pork simultaneously.
Meat quality determines primarily of the physicochemical property of meat, the chemical composition of meat and its nutritive value in close relations; Organoleptic indicator such as yellowish pink, retentiveness, tenderness and succulence, the marble grain scoring etc. of meat directly affect the acceptance level of consumer to meat.The edible quality of intramuscular fat content and pork is closely related, and can affect the tenderness of pork, local flavor, yellowish pink, Coefficient shrinkage and marble grain scoring etc., be the key factor affecting meat quality.Content is moderate and the marble grain be evenly distributed can make the delicious succulence of meat, mouthfeel good; It is stiff dull that content crosses meat at least.The local flavor succulence of meat is improved with the increase of intramuscular fat content, and improving intramuscular fat will the tenderness of corresponding improvement meat and succulence.Much research shows, the intramuscular fat content of 2% ~ 3% is an ideal standard of fresh pork product, but current commodity tri-crossbreeding seldom can reach such standard.Therefore, appropriateness increases pork intramuscular fat content, improves local flavor and the mouthfeel of pork, make its more easily accept by consumer, tool is of great significance.Affect intramuscular fat and meat qualitative factor a lot, the content of nutrition regulation to intramuscular fat has certain effect, but it is more difficult to significantly improve intramuscular fat content.In daily ration, protein (amino acid) and energy ratio determine the ratio of pig body protein and fat deposition.Low albumen and energy level can cause higher trunk and intramuscular fat level, produce positive influences to meat.But low energy low-protein diet can affect the speed of growth of pig, increase the food consumption of pig, reduces lean meat percentage, and then increases aquaculture cost.High-energy high-protein can promote lean meat deposition but can not improve the content of pig body intramuscular fat, and meat taste is poor.Also many preparation techniques improving intramuscular fat content are had at present, as added betaine, vitamin E, Organic Chromium, arginine etc., but add separately or proportioning improper, cause the limited efficiency improved, increase cost, and be reduce fat deposition mostly, remarkable result is not had to the improvement of intramuscular fat.It is different that different additive regulates and controls lipometabolic mechanism, how to play its combined effect and need to be excavated further.
Summary of the invention
The object of this invention is to provide a kind of feed improving pork intramuscular fat and improve meat, this feed can increase tri-crossbreeding intramuscular fat content, improve meat.
Technical problem to be solved by this invention is realized by following technological means: a kind of feed improving pork intramuscular fat and improve meat, comprises the component of following mass percent:
Corn 65%-75%, dregs of beans 5-20%, wheat bran 5-10%, rice bran 2-7%, arginine 0.3%-1%, CLA 0.5-2%, alfalfa meal 2-7%, stone flour 1-2%, feed addictive 1.5-8%.
In described feed addictive, be made up of the component of following mass ratio:
Salt: lysine: calcium monohydrogen phosphate: Choline Chloride: mould inhibitor: multidimensional: many ore deposits: vitamin E: the long element of benefit: lactic acid bacteria: carrier=60: 60: 60: 20: 20: 5: 20: 5-20: 40-80: 1-5: 1-100.
The Main Ingredients and Appearance of described multidimensional is vitamin A, vitamin D, vitamin E, Vitamin K3, vitamin B1, vitamin B2, vitamin B6, vitamin B12, niacinamide, calcium pantothenate, folic acid and biotin, is vitamins feed addictive.
The Main Ingredients and Appearance in many ore deposits described above is copper sulphate, ferrous sulfate, zinc oxide, manganese sulfate, calcium iodate, sodium selenite, is the mineral additive for feed of growing and fattening pigs.
Pig metabolizable energy/crude protein of the present invention is 0.18 ~ 0.28; Within the scope of total protein levels 12-14%, digestible aminoacids lysine: can methionine be digested: can threonine=100 be digested: 30 ~ 40: 68 ~ 75, on this basis nutrient formulation be adjusted.
The production method of feed of the present invention is: according to component and the weight percent proportioning thereof of described mixed feed, fully mixed by all components, afterwards by metering encapsulation.
Advantage of the present invention is:
(1) feed provided by the invention is not falling on low-energy basis, reduces conventional raw material in short supply as the use amount of corn, dregs of beans, increases the use amount of unconventional raw material, saves feed resource.Intramuscular fat content in pork can be significantly improved, it does not increase the thickness of backfat and do not extend the time limit of feeding prerequisite under increase intramuscular fat content more than 35%.
(2) contain the additives such as microorganism formulation, vitamin, antioxidant in the present invention, improve resisting stress, the oxidation resistance of swinery, improve pig intestine microenvironment, keep microecological balance, improve meat quality, and alleviate pig house stink.
(3) feed of the present invention is not containing antibiotic, reduces environmental pollution.
(4) feed cost of the present invention is low, reduces by 1% with the cost of existing feed, is applicable to suitability for industrialized production.
