Description
Technical field
The present invention relates to a kind of feed additive and production technology thereof, be specifically related to a kind of for improving barren sow fat meat quality
Feed additive and production technology, belong to field of feed additive technology.
Background technology
Carnis Sus domestica is meat food main in people's daily life, and along with the improvement of people's living standard, consumer is to pig
The requirement of meat is more and more higher.People do not require nothing more than nutritious, safe and sanitary to Carnis Sus domestica, it is also desirable to have good wind
Taste and mouthfeel, and fat is the important substance determining Meat Flavor with mouthfeel.Fat is due to can in the feedstuff of animal ingestion
Digestion nutrient substance is by sorption enhanced, and accumulation forms in vivo.According to the difference of deposition site, pork fat is broadly divided into skin
Lower fat, intramuscular fat, intramuscular fat, they are to determine quality of pig trunk and the key factor of meat flavor.The local flavor of Carnis Sus domestica
Resulting from the fatty acid in fatty tissue and the water-soluble substances hydrolysis in gastronomical process, the thinnest Carnis Sus domestica palatability is also
Bad, but fat content has deviated from the most again the preference of consumer.
Numerous results of study shows, affects pig flesh flavor and the topmost factor of quality is intramuscular fat, intramuscular fat
It is ideal that content controls in the range of 2.5%-3.5% pork tenderness, local flavor, succulence, and the Carnis Sus domestica under this state is fresh and tender
Succulence, local flavor are good, good mouthfeel.When intramuscular fat content is less than 2.5%, quality and the mouthfeel of Carnis Sus domestica are poor, and are higher than
When 3.5%, the most no longer improve pig flesh flavor.For indivedual local pig breeds, such as Luchuan pig, intramuscular fat content is suitable
During more than 3.5%, it also it is ideal value category.And subcutaneous fat (crude fat) affects mouthfeel and the product of Carnis Sus domestica the most to a certain extent
Matter, the higher Carnis Sus domestica of crude fat content is the most greasy, the most popular with consumers.
The existing frequently-used feed additive improving meat quality is mainly Chinese herbal medicine formula or chemical agent, often only
Crude fat content can be reduced to a certain extent, improve lean meat percentage, be but difficult to meet the reasonable demand of intramuscular fat content, intramuscular fat
Fat content is on the low side, it is impossible to improve meat quality well, and chemical agent improper use is also easy to cause drug residue.
Therefore, rationally innovate feed addictive prescription, suitably increase Carnis Sus domestica intramuscular fat content, reduce crude fat content,
Control the suitable fertilizer degree of Carnis Sus domestica, make Carnis Sus domestica " fertilizer and oiliness ", the local flavor of Carnis Sus domestica, mouthfeel and quality can be greatly enhanced.
Summary of the invention
It is an object of the invention to provide a kind of feed additive for improving barren sow fat meat quality and production technology thereof,
Wherein, this feed additive is by rationally innovating formula, it is possible to suitably increase Carnis Sus domestica intramuscular fat content, reduces crude fat and contains
Amount, control barren sow suitably fertilizer degree, improve barren sow fat meat quality, for consumer offer succulence healthy and safe, fresh and tender, fertilizer and oiliness,
The high-quality pork that local flavor is good, in good taste.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that:
