Description
Technical field
The present invention relates to field of fodder, be specifically related to the functional compound additive premix of a kind of broiler chicken and application thereof.
Background technology
Chinese nation's cooking culture is always particular about and is looked good, smell good and taste good.Along with the raising of living standards of the people, by the increase of measuring, the raising of flavor quality is turned to especially to the requirement of livestock products.The evaluation index of Meat Flavor quality is a lot, mainly delicate flavour and fragrance.For chicken, what consumer valued more is its delicate flavour.Maximum to the contribution of chicken delicate flavour, the decisive factor of delicate flavour has a variety of, may be summarized to be amino acids and ucleotides, and wherein the contribution of inosinicacid to chicken delicate flavour is maximum, has become the important indicator weighing meat delicate flavour.The kind of chicken, sex, age in days and tissue etc. have impact in various degree to imp content, the imp content of local high-quality chicken kind is apparently higher than this fast large fowl kind, Muscle of chicken imp content is higher than quick broiler chicken at a slow speed, but this low production performance can not meet the demand of consumer for chicken quantity.Under how giving full play to the prerequisite of fast large-scale broiler production potentiality, improving its flavor quality is the key point addressed this problem.
In recent years, domestic and international breeding expert is studying the genomic constitution of the enzyme relevant with inosinicacid metabolism, uses breed breeding and molecular biology method to improve the content of inosinicacid in livestock and poultry muscle.These approach cycles are long, but also there is safety issue.Therefore, Animal nutrition scholar attempts the content improving inosinicacid in livestock and poultry muscle by finding new green feed additive, improves the flavor quality of meat.Xiao Hong (2010) reports, adds the content that Tea Polyphenols significantly can increase inosinicacid in chicken.Howaidi (1997) thinks, adds betaine and can improve chest muscle imp content in daily ration.Qiao Yunfang (2006) proves, adds imp content in L-glutamine group chicken chest and adds 23.29% and 19.63% respectively.Jiang Shouqun (2007) reports, the isoflavones added in daily ration improves the imp content in chicken due to its antioxygenic property.But so far, the research of Chinese scholars to feed addictive regulation and control chicken meat flavor quality aspect is still in the starting stage, to the more aobvious shortage of the control technique of its delicate flavour quality, still belongs to blank to the research and development of its joint product.
But feed addictive is but difficult to take into account on the chicken flavor quality characteristic of broiler chicken and the impact of production performance.The present invention selects multiplely have the feed addictive of raising effect as test material to chicken meat flavor quality, the action effect of its different additive amount and combination thereof is evaluated, screened, defines the functional composite feed additive that the production performance, the carcass quality that neither reduce fast large-scale broiler chicken can improve again its chicken imp content.
Therefore, the present invention for the flavor quality effectively improving fast large-scale broiler chicken, meet the producer for the quantity of chicken meat product and the dual requirements of consumer to its delicate flavour quality significant.
Summary of the invention
Therefore, the object of this invention is to provide the functional compound additive premix of a kind of broiler chicken.
Another object of the present invention provides the premix of above-mentioned broiler chicken functional compound additive for improving the application of the functional compound additive premix of broiler chicken.
The functional compound additive premix of broiler chicken according to the present invention, comprises isoflavones 20 ~ 60mg/kg, glutamine 300 ~ 800mg/kg, betaine 500 ~ 1200mg/kg, Tea Polyphenols 400 ~ 1200mg/kg, and described carrier is stone flour.
Additive premix organoleptic requirements uniform color of the present invention is consistent, without moldy metamorphism, caking and peculiar smell, differently to smell; Moisture requirement is not higher than 10%; Grinding particle size requires all to analyze sieve by 2.5mm, and 1.25mm analyzes oversize should be greater than 10%; The coefficient of variation (CV) of mixture homogeneity is not more than 5%.
The using method of premix of the present invention makes an addition in full price batch according to the ratio of 5kg/ ton.
Premix of the present invention can increase substantially inosinicacid deposition in broiler chicken chicken, effectively improves the delicate flavour quality of broiler chicken chicken.Premix of the present invention can reduce the abdomen fat content of broiler chicken, has no adverse effects to meat chicken production performance and carcass quality, is suitable for being applied to fast large-scale broiler chicken.

The mechanism of action of the functional compound additive premix of embodiment 3 broiler chicken
Experimental design, feeding and management and process for butchering are with embodiment 2.Same area in right side chest muscle samples, and for the mensuration that inosinicacid metabolic enzyme is lived, comprises ATP digestive enzyme, creatine kinase, ADA, alkaline phosphatase and 5'Nueleotidme (see table 5).ATP digestive enzyme, creatine kinase, ADA are the key enzymes in inosinicacid anabolic process, and alkaline phosphatase and 5'Nueleotidme are the key enzymes in inosinicacid degradation process.Get left pectoral, for taste test, result of the test is shown in Fig. 2.
Result shows, add the ATP digestive enzyme in functional compound additive premix group chicken chest of the present invention, creatine kinase, ADA activity be significantly higher than control group (P<0.05), alkaline phosphatase and 5'Nueleotidme active significantly lower than control group (P<0.05).Compare with other compound additive groups, add creatine kinase and ADA activity in functional compound additive premix group chicken chest of the present invention and significantly improve, 5'Nueleotidme obviously reduces (P<0.05).After this illustrates and adds this functional compound additive premix, by the key enzyme enzyme imp content that have impact in broiler chicken chicken alive of regulation and control Muscle of chicken inosinicacid metabolic process.By taste test, find that the delicate flavour scoring of brisket is more various than other and significantly improve, reach more than 40%.In addition, glutamine adds the substrate content in inosinicacid metabolic process, and isoflavones has the effect maintaining eucaryotic cell structure after animal dead, prevent nutriment to run off; Betaine can improve methyl in inosinicacid anabolism; And Tea Polyphenols also has scavenging free radicals, improves metabolic enzyme effect alive.In a word, these four kinds of additives complement each other, indispensable, combine interpolation and have played the effect improving Muscle of chicken delicate flavour quality preferably.And to raising broiler growth and minimizing abdomen fat, there is effect preferably.
The impact that in table 5 DIFFERENT FEED Additive On Chickens chest muscle, inosinicacid metabolizing enzyme is lived
