Description
Technical field
The invention belongs to technical field of animal, and in particular to a kind of that pork intramuscular fat can be improved and improve meat
Feed.
Background technique
Requirement with pig aquaculture large-scale degree and people to meat is continuously improved, the raising of live pig production performance
It becomes increasingly conspicuous with the contradiction of meat quality, it is difficult to which the economic benefit for combining aquaculture and consumer are to the need of high-quality pork
It asks.
Meat quality is mainly determined that the chemical component of meat and its nutritive value are in close relations by the physicochemical property of meat；
The organoleptic indicator of meat such as yellowish pink, retentiveness, tenderness and succulence, marble grain scoring directly affect consumer to meat
Acceptance level.The edible quality of intramuscular fat content and pork is closely related, can influence the tenderness of pork, flavor, yellowish pink, be
Waterpower and marble grain scoring etc. are an important factor for influencing meat quality.Content is moderate and the marble grain energy that is evenly distributed
Make the delicious succulence of meat, in good taste；The excessively few then meat of content is stiff dull.The flavor succulence of meat with intramuscular fat content increasing
Add and improve, the tenderness and succulence of meat will accordingly be improved by improving intramuscular fat.Many studies have shown that 2%~3% flesh
Interior fat content is an ideal standard of fresh pork product, but current commodity tri-crossbreeding can seldom reach in this way
Standard.Therefore, appropriateness increases pork intramuscular fat content, improves the flavor and mouthfeel of pork, it is made to be easier to be connect by consumer
By having a very important significance.It influences intramuscular fat and there are many meat qualitative factor, nutrition regulation has the content of intramuscular fat
Certain effect, but it is relatively difficult to significantly improve intramuscular fat content.Protein (amino acid) is determined with energy ratio in daily ration
The ratio of pig body protein and fat deposition is determined.Low albumen and energy level can lead to higher trunk and intramuscular fat
Level generates positive influences to meat.But low energy low-protein diet will affect the speed of growth of pig, increase the food consumption of pig,
Lean meat percentage is reduced, and then increases aquaculture cost.High-energy high-protein can promote lean meat deposition but cannot improve pig body intramuscular fat
Content, meat taste are poor.Also there are many preparation techniques for improving intramuscular fat content at present, such as add glycine betaine, vitamin E,
Organic Chromium, arginine etc., but individually add or match improper, cause improveds effect limited, increase cost, Er Qie great
It is mostly to reduce fat deposition, to the no remarkable result of the improvement of intramuscular fat.Different additive regulates and controls the mechanism of fat metabolism not
Together, a combination thereof effect how is played to need further to be excavated.
Summary of the invention
The object of the present invention is to provide a kind of feed that pork intramuscular fat can be improved and improve meat, which can increase
Add tri-crossbreeding intramuscular fat content, improve meat.
The technical problem to be solved by the present invention is to realized by the following technical means: it is intramuscular that pork can be improved in one kind
Fat and the feed for improving meat, include the following components'mass percentage:
Corn 65%-75%, dregs of beans 5-20%, wheat bran 5-10%, rice bran 2-7%, arginine 0.3%-1%, conjugated linoleic acid
0.5-2%, alfalfa meal 2-7%, mountain flour 1-2%, feed addictive 1.5-8%.
In the feed addictive, it is grouped as by the group of following mass ratio:
Salt: lysine: calcium monohydrogen phosphate: choline chloride: mould inhibitor: multidimensional: more mines: 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 ingredient of the 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 are vitamins feed addictives.
The main ingredient of more mines as described above is copper sulphate, ferrous sulfate, zinc oxide, manganese sulfate, calcium iodate, selenous acid
Sodium is the mineral additive for feed of growing and fattening pigs.
Pig metabolic energy/crude protein of the invention is 0.18~0.28；Within the scope of total protein levels 12-14%, ammonia can be digested
Base acid lysine: methionine can be digested: can digests threonine=100: 30~40: 68~75, on this basis to nutrient formulation
It is adjusted.
The production method of feed of the invention is: matching according to the component and its weight percent of the mixed feed, by institute
There is component to be sufficiently mixed, later by metering encapsulation.
The invention has the advantages that
(1) feed provided by the invention reduces conventional raw material such as corn, dregs of beans in short supply on the basis of not reducing energy
Usage amount, increase the usage amount of unconventional raw material, save feed resource.Intramuscular fat content in pork can be significantly improved, it
Increase by 35% or more intramuscular fat content under the premise of not increasing the thickness of backfat and not extending the feeding time limit.
(2) in the present invention containing the additives such as microorganism formulation, vitamin, antioxidant, improve swinery resisting stress,
Oxidation resistance improves pig intestine microenvironment, keeps microecological balance, improves meat quality, and mitigate pig house stink.
(3) feed of the invention is free of antibiotic, reduces environmental pollution.
(4) feed cost of the present invention is low, reduces by 1% with the cost of existing feed, is suitble to industrialized production.
