Description
Technical field
The present invention relates to a kind of stage division of belt leather sheet hog on hook, relate in particular to the stage division of belt leather sheet hog on hook in a kind of ternary pig, belong to a kind of stage division of pork, be mainly used in to the interior ternary pig cultured in China and outside the pork classification of ternary pig.
Background technology
The hog on hook classification is meant in order to adapt to the demand of market to high lean meat percentage, according to the part economic characters of hog on hook, as carcass lean meat percentage and carcass weight etc., according to certain standard, artificial hog on hook is divided into different grades when requiring to butcher.And the hog on hook of different brackets is connected with different market purchasing price, thereby deburring swashs pig industry and pig is butchered industrial expansion, instruct and raise the purchase and the processing of raising on a household basis pig and meat production processing enterprise.
The purpose of hog on hook classification is to determine some characteristic of pig carcass, and according to the value of these characteristic index decision pig carcass and products thereof, makes the buying and selling parties have common standard to follow, and under fair and reasonable transaction principle, prevents to produce dispute.The existing very long history of the research of external relevant hog on hook classification technique, countries in the world basis national conditions has separately successively been set up the hog on hook grade scale of oneself, and classification technique has also experienced by the very long evolution of artificial classification to the intelligent equipment classification.The meat industry of China is in the fast-developing stage, large-scale meat is butchered processing enterprise and is continued to bring out, but the hog on hook staging hierarchy of China is very backward, respectively butchering producer all formulates according to the enterprise operation characteristics voluntarily to hog on hook stage division standard, lack unified practical stage division, the original hog on hook grade scale of China has not met the enterprise practical production requirement, and the good hog on hook stage division of grading effect is not formulated as yet and is announced, is a kind of huge shortcoming as the first in the world Swine Production and pork consumption big country.
At present, domestic meat producing plant is when concluding the business live pig with live pig Broker or raiser, the clearing of many employing live pigs, the live pig purchase means of payment is science not, some large enterprises have adopted and have killed the back by rank " killing calculation " pattern with Broker or raiser's clearing, require enterprise classification standardization and fairness more more.Adopt the method for artificial classification that hog on hook is carried out classification at present mostly, but because artificial classification is that some related economic proterties to hog on hook are (as body weight, the bodily form, girth of a garment degree, muscle development degree etc.) rule of thumb carry out artificial, subjective estimation, result according to estimation carries out classification and pays Swine Production person's price with this, but rely on the estimation mode of sense organ to be subjected to the time, the difference of factor such as place and personnel and cause classification results difference to occur, make the order of accuarcy of classification results reduce greatly, thereby often cause Broker or raiser's strong dissatisfaction.
In CNS GB/T9959.1-2001 " bright, freeze sheet pork ", in standard 4.6 gradings, aquatic foods are frozen the sheet hog on hook and be divided into one-level, secondary and three grades.This stage division be with aquatic foods freeze the 6th of sheet pork with the 7th rib in the middle of parallel to sixth dorsal vertebra spinous process front lower place, and the fat deposit thickness that removes after the peeling is as the criterion.Except that one-level pig regulation fat deposit thickness, also increase the requirement of sheet hog on hook weight in addition, and secondary and three grades of hogs on hook are not done requirement to weight.But because Chinese current pig-breeding industry is comparatively disperseed; the live pig that existing scale and standardized breed factory culture can't be satisfied the demand in the amount of butchering and market at all; the live pig that butcher most of slaughterhouse all derives from the small-sized raiser in the vast rural area; it is bigger to purchase the live pig kind and the size differences of coming like this; even the live pig of same kind and size; also there is bigger difference in each live pig on the bodily form and skeleton; if press CNS GB/T9959.1-2001 " aquatic foods; freeze sheet pork " 4.6 grading standards come these hogs on hook are carried out classification; the used method of classification is only declared mark and is complied with as unique with fat; the grading effect of this stage division must be not good enough, obviously can not satisfy the raiser; the needs in slaughterhouse and market.And this stage division only is divided into three grades with hog on hook, and the not enough refinement of classification makes that price differs bigger between three other hogs on hook of level that obtain after the classification, thereby brought inconvenience for the transaction and the clearing of hog on hook, does not reach desirable grading effect.
As far back as nineteen twenty-two, Canada just begins to set up the hog on hook hierarchy system.To nineteen forty-four, the hog on hook grade scale begins according to national regulation compulsory implement in China in Canada.Around here, some animal husbandry developed countries of US and European also begin to carry out at home hog on hook classification project.Through the development in a nearly century, external hog on hook stage division is progressively perfect, and to the development of high-tech art field, the external hog on hook stage division that adopts mainly contains following several by the artificial stage division that begins:
1, the method that adopts photoelectricity probe-type grading instrument to carry out classification:
The classification principle of this method is to use the near infrared ray reflective principle, identification and measurement hog on hook back fat and muscle thickness, and carcass lean meat percentage and rank are calculated automatically, are shown by system's embedded software.
The advantage that this stage division exists is simple operation, moderate, the classification degree of accuracy is higher, measuring speed is fast, but, there is bigger shortcoming in this method, because different pig kind, different build situations can produce bigger influence to the prediction effect of photoelectricity probe-type classifying equipoment, and distinct device uses the lean meat percentage predictive equation of state also inequality, that is to say need be according to the actual conditions of different regions market pig, the predictive equation of this area's market pig carcass lean meat percentage can be accurately predicted in foundation, therefore need be in China according to the actual conditions of Chinese commodity pig, the predictive equation of Chinese commodity hog on hook lean meat percentage can be accurately predicted in foundation, makes this stage division have certain locality in the use.
2, the method that adopts live pig image grading instrument (image Meater) to carry out classification:
The classification principle of this method is to set up image and data model draws lean meat percentage by visual forming technique.
The shortcoming that this stage division exists is identical with the method that employing photoelectricity probe-type grading instrument carries out classification, need be according to the actual conditions of different regions market pig, and the predictive equation of this area's market pig carcass lean meat percentage can be accurately predicted in foundation.
3, other stage division:
As adopt ultrasonic scanning to carry out the method for classification, the method that the employing electromagnetic scanning carries out classification etc., but the employed analytical instrument of these methods costs an arm and a leg, and requisite space is big, the use cost height, that promotes at present has little significance.
Though at present some stage division can the success use abroad, as adopt photoelectricity probe-type grading instrument stage division, adopt live pig image grading instrument to carry out the method etc. of classification, but these stage divisions have stronger region, applicable surface is wideless, be difficult to use in China, these national conditions with China are relevant.External aquaculture high mature, the aquaculture degree is high to be concentrated, and kind is single relatively; And China is vast in territory, has nearly 64 of local pig varieties, and first of the world, various places market pig situation complexity is cultured and disperseed, and the raising kind is uneven, feeding manner and breeding cycle disunity.External intelligent classifying equipoment is when simulation lean meat percentage predictive equation and data model, must be earlier at Chinese commodity pig characteristics, live pig to different cultivars is known the real situation comprehensively, and then set up and simulate lean meat percentage predictive equations and data models in a large number, thereby set up the forecast model that tallies with the national condition, but because China's national situation is special, the expense that foundation a large amount of simulation lean meat percentage predictive equations and data model are produced will be considerably beyond instrument itself, this has just improved workload greatly, has increased production cost.
Some comparatively general pork stage divisions are also arranged at present, as open day was on 03 29th, 2006, publication number is in the Chinese patent of CN1751812, a kind of division methods of pork colour credit rating is disclosed, this method is gathered the photo of fresh meat by digital camera, then by the Computerized intelligent classification, thereby determine the credit rating of pork, this method is only judged the grade of pork by the color relation of pork, make grading effect relatively poor, and this method is to use digital camera to gather the photo of fresh meat, makes the photo color of camera collection and the color in kind of pork difference can occur, thereby can influence the accuracy of this method greatly.
In sum, also there is not a kind of grading effect good at present, widely applicable hog on hook stage division, especially also do not have a kind of to the interior ternary pig cultured in China and outside the hog on hook stage division of ternary pig, thereby make that the classification of pork is not accurate enough, greatly reduce the utilization rate of pork, make the transaction of pork be difficult to realize the pattern of determining the price with matter, this brings great negative effect with regard to the production of giving pork, especially have influence on the production of high-quality pork, make the development of pig industry have bigger resistance.
Summary of the invention
The objective of the invention is to overcome above shortcomings in the prior art, a kind of classification operation is simple, cost is low and provide, the classification accuracy height of internal ternary pig and outer ternary pig, the stage division of widely applicable belt leather sheet hog on hook.
The present invention addresses the above problem the technical scheme that is adopted: the stage division of this belt leather sheet hog on hook comprises and selects carcass operation and system trunk operation, described system trunk operation comprises unhairing successively, cuts open the chest, goes internal organ, removes tack and extracts three gland steps, and its characteristics are: also comprise and weigh and measure the fat operation, survey the muscle operation, survey tail fat operation and carcass grading operation;

The heavyweight code of hog on hook is shown in the table 1 first tabulation, and secondary series is represented the scope of hog on hook gravimetric value, can check in heavyweight code in the corresponding hog on hook gravimetric value scope by table 2.In hog on hook weight hierarchy index table of the present invention, by claiming to such an extent that the gravimetric value of hog on hook just can check in corresponding hog on hook heavyweight, the heavyweight of hog on hook uses code " B1 " among the present invention, " B2 ", " B3 ", " B4 ", " B5 ", " B6 ", " B7 ", " B8 ", " B9 " and " no rank " represents, a rank is represented one section weight range, these codes only are the symbols of expression hog on hook heavyweight, mainly when inquiry hog on hook weight fat thickness matrix table, use, certainly, be used to represent the code of hog on hook heavyweight also can use other symbols to represent among the present invention.As shown in Table 1, when 22kg among the present invention≤hog on hook weight＜24kg, the heavyweight of hog on hook is B1; When 24kg among the present invention≤hog on hook weight＜27kg, the heavyweight of hog on hook is B2; When 27kg among the present invention≤hog on hook weight＜30kg, the heavyweight of hog on hook is B3; When 30kg among the present invention≤hog on hook weight＜33kg, the heavyweight of hog on hook is B4; When 33kg among the present invention≤hog on hook weight＜36kg, the heavyweight of hog on hook is B5; When 36kg among the present invention≤hog on hook weight＜kg39, the heavyweight of hog on hook is B6; When 39kg among the present invention≤hog on hook weight＜41kg, the heavyweight of hog on hook is B7; When 41kg among the present invention≤hog on hook weight＜45kg, the heavyweight of hog on hook is B8; When 45kg among the present invention≤hog on hook weight＜50kg, the heavyweight of hog on hook is B9; When the hog on hook weight＜22kg among the present invention or hog on hook weight 〉=50kg, the heavyweight of hog on hook is " nothing ", just the hog on hook weight in this scope is not carried out classification, represent that promptly this hog on hook is an off standard, under normal conditions, the heavyweight of hog on hook among the present invention is if " nothing ", the weight of then representing hog on hook is 18kg≤hog on hook weight＜22kg or 50kg≤hog on hook weight≤55kg basically, this is owing to used hog on hook among the present invention generally all is that the live pig that grows up is prepared from, so the weight of these hogs on hook often can be greater than 55kg, usually can be less than 18kg yet, this is common practise to one skilled in the art, no longer describes in detail herein.
The present invention weighs and measures amount fat step in the fat operation is to adopt CNS GB/T9959.1-2001 that the back-fat thickness of hog on hook is measured, through obtaining the back-fat thickness value of hog on hook after measuring, used CNS GB/T9959.1-2001 is measured as prior art to the back-fat thickness of hog on hook among the present invention, no longer describes in detail herein.Use the back-fat thickness value to inquire about hog on hook back-fat thickness hierarchy index table of the present invention then and obtain the back-fat thickness level of hog on hook, table 2 is exactly a hog on hook back-fat thickness hierarchy index table of the present invention, shown in table 2 is specific as follows:
Table 2 hog on hook back-fat thickness hierarchy index table
| The back-fat thickness level | Back-fat thickness value scope/mm |
| Do not have | Back-fat thickness≤6 |
| C1 | 6＜back-fat thickness≤10 |
| C2 | 10＜back-fat thickness≤20 |
| C3 | 20＜back-fat thickness≤26 |
| C4 | 26＜back-fat thickness≤30 |
| C5 | 30＜back-fat thickness≤36 |
| C6 | 36＜back-fat thickness≤40 |
| C7 | 40＜back-fat thickness≤46 |
| C8 | 46＜back-fat thickness≤50 |
| Do not have | Back-fat thickness＞50 |
The code of back-fat thickness level is shown in the table 2 first tabulation, secondary series is represented the scope of back-fat thickness value, the just corresponding back-fat thickness level of back-fat thickness value scope, wherein, the back-fat thickness level uses code " C1 ", " C2 ", " C3 ", " C4 ", " C5 ", " C6 ", " C7 ", " C8 " and " no rank " to represent, back-fat thickness level of a coded representation, this code mainly uses when inquiry hog on hook weight fat thickness matrix table, certainly, the employed code of back-fat thickness also can use other symbols to represent among the present invention.The present invention just can check in back-fat thickness level under the corresponding back-fat thickness by hog on hook back-fat thickness hierarchy index table of the present invention after measuring hog on hook back-fat thickness value.As shown in Table 2, when the 6mm＜back-fat thickness among the present invention≤10mm, the back-fat thickness level of hog on hook is C1; When the 10mm＜back-fat thickness among the present invention≤20mm, the back-fat thickness level of hog on hook is C2; When the 20mm＜back-fat thickness among the present invention≤26mm, the back-fat thickness level of hog on hook is C3; When the 26mm＜back-fat thickness among the present invention≤30mm, the back-fat thickness level of hog on hook is C4; When the 30mm＜back-fat thickness among the present invention≤36mm, the back-fat thickness level of hog on hook is C5; When the 36mm＜back-fat thickness among the present invention≤40mm, the back-fat thickness level of hog on hook is C6; When the 40mm＜back-fat thickness among the present invention≤46mm, the back-fat thickness level of hog on hook is C7; When the 46mm＜back-fat thickness among the present invention≤50mm, the back-fat thickness level of hog on hook is C8; When back-fat thickness≤6mm among the present invention or back-fat thickness＞50mm, the back-fat thickness level of hog on hook is not just carried out classification to the back-fat thickness in this scope for not having.Generally, when the back-fat thickness level among the present invention is off grade, the back-fat thickness of hog on hook is often at 3mm≤back-fat thickness≤6mm or 50mm＜back-fat thickness≤55mm, this is owing to used hog on hook among the present invention generally all is that the live pig that grows up is prepared from, so the back-fat thickness of these hogs on hook often can be greater than 55mm, usually can be less than 3mm yet, this is common practise to one skilled in the art, no longer describes in detail herein.
The present invention weighs and measures in the fat operation and obtained heavyweight and back-fat thickness level respectively through weigh step and amount fat step, just enter then weight fat thickness value step, operating weight level and back-fat thickness level are inquired about the weight fat thickness value that hog on hook weight fat thickness matrix table of the present invention just can obtain hog on hook.Ternary hog on hook weight fat thickness matrix table and outer ternary hog on hook weight fat thickness matrix table in hog on hook weight fat thickness matrix table is divided among the present invention, if the raw material carcass is interior ternary pig carcass, the weight fat thickness value of ternary pig carcass in then obtaining by ternary hog on hook weight fat thickness matrix table in inquiring about; If the raw material carcass is outer ternary pig carcass, then obtain the weight fat thickness value of outer ternary pig carcass by inquiring about outer ternary hog on hook weight fat thickness matrix table, among the present invention in the ternary hog on hook use code A1 to represent, outer ternary hog on hook uses code A2 to represent.Table 3 is exactly an interior ternary hog on hook weight fat thickness matrix table of the present invention, and table 4 is exactly an outer ternary hog on hook weight fat thickness matrix table of the present invention, and table 3 and table 4 are as follows respectively:
Ternary hog on hook weight fat thickness matrix table in the table 3
The outer ternary hog on hook of table 4 weight fat thickness matrix table
The present invention is after heavyweight that obtains hog on hook and back-fat thickness level, just can obtain the weight fat thickness value of corresponding hog on hook by question blank 3 or table 4, weight fat thickness value among the present invention is a numerical value, can express the quality quality of corresponding hog on hook to a certain extent by the size of this numerical value, if the numerical value of weight fat thickness value is big more, the quality of then representing hog on hook is good more, and lean meat percentage is high more, economic worth is big more; If the numerical value of weight fat thickness value is more little, represent that then the quality of hog on hook is poor more, lean meat percentage is low more, economic worth is more little.Ternary hog on hook weight fat thickness matrix table obtained corresponding weight fat thickness value with outer ternary hog on hook weight fat thickness matrix table in ternary pig carcass and outer ternary pig carcass were inquired about respectively among the present invention, because interior ternary pig is different with the kind of outer ternary pig, make that the meat between them is variant, the internal ternary pig of the present invention carcass uses different hog on hook weight fat thickness matrix tables to inquire about with outer ternary pig carcass, improved the accuracy of classification of the present invention greatly, made that classification of the present invention is better.By table 3 and table 4 as can be known, when the heavyweight of hog on hook to be fractionated and/or back-fat thickness level were " nothing " among the present invention, the corresponding weight fat thickness of this hog on hook value was " 0 " just.
Introduce the survey muscle operation among the present invention below, be mainly used in the plumpness of measuring leg muscle behind the hog on hook in the survey muscle operation among the present invention, be as the criterion with the whole muscle thickness of hog on hook back leg during measurement, it is same as the prior art or close to measure behind the hog on hook thickness of leg muscle among the present invention.Obtain the whole muscle thickness value of back leg of this hog on hook by the thickness of leg muscle behind the measurement hog on hook, determine corresponding plumpness according to the whole muscle thickness value of back leg then, plumpness among the present invention uses code " D1 ", " D2 " and " D3 " to represent, certainly, be used among the present invention represent that the code of plumpness also can use other symbols as required.When back leg integral body muscle thickness value was greater than 165mm among the present invention, the plumpness of hog on hook was the D1 level; When back leg integral body muscle thickness value was less than 150mm among the present invention, the plumpness of hog on hook was the D3 level; When the whole muscle thickness value of back leg among the present invention was between 150-165mm, the plumpness of hog on hook was the D2 level.But under normal conditions, when the plumpness of the whole muscle of back leg was the D1 level in the present invention, the one-tenth-value thickness 1/10 of the whole muscle of back leg was often greater than 165mm and between smaller or equal to 190mm, and the whole muscle thickness value of back leg is then less relatively greater than the hog on hook of 190mm; When the plumpness of the whole muscle of back leg was the D3 level among the present invention, the one-tenth-value thickness 1/10 of the whole muscle of back leg was often more than or equal to 110mm and between less than 150mm, and the whole muscle thickness value of back leg is then less relatively less than the hog on hook of 110mm.Used hog on hook generally all is that the live pig that grows up is prepared among the present invention, so the whole muscle thickness value of the back leg of these hogs on hook often can be greater than 190mm, usually can be less than 110mm yet, this is common practise to one skilled in the art, no longer describes in detail herein.After having obtained the plumpness of hog on hook, the muscle plumpness value that just can use the hog on hook muscle plumpness concordance list among the present invention to inquire about hog on hook, table 5 is exactly a hog on hook muscle plumpness concordance list of the present invention, shown in table 5 is specific as follows:

Table 6 hog on hook tail fat degree concordance list
| Tail fat degree | Tail fat degree value |
| E1 | 0 |
| E2 | -10 |
| E3 | -20 |
In the hog on hook tail fat degree concordance list of the present invention, the tail fat degree of hog on hook is shown in first tabulation, secondary series is represented the tail fat degree value of hog on hook, and the tail fat degree value among the present invention also is a numerical value, and the numerical value of tail fat degree value is big more, the fat of expression hog on hook is thin more, usually gluteus medius is big more, and as when tail fat degree is E1, tail fat degree value is 0, this moment, the fat of corresponding hog on hook was thin more, and gluteus medius is bigger; The numerical value of tail fat degree is more little, and the fat of expression hog on hook is just thicker, and gluteus medius is less usually, and as when tail fat degree is E3, tail fat degree value is-20, and this moment, the fat of corresponding hog on hook was thick more, and gluteus medius is more little.Tail fat degree value among the present invention mainly is meant the tail fat degree value of gluteus medius highest point in the hog on hook, and tail fat degree mainly is meant the tail fat degree of gluteus medius highest point in the hog on hook.
The present invention has obtained weight fat thickness value through after the top operation, muscle plumpness value and tail fat degree value, just entered the carcass grading operation among the present invention below, carcass grading operation among the present invention is the weight fat thickness value with hog on hook, muscle plumpness value and the value addition of tail fat degree and obtain total value, re-use the hog on hook level index table among total value inquiry the present invention and obtain the rank of hog on hook, rank among the present invention is used code " 1 grade " respectively, " 2 grades ", " 3 grades ", " 4 grades ", " 5 grades ", " 6 grades ", " 7 grades ", " 8 grades " and " 9 grades " are represented, rank is that 1 grade hog on hook is best in quality among the present invention, the quality of hog on hook is variation along with other increase of level, 9 grades among the present invention is exactly to wait for outer rank in fact, belong to the poorest one-level hog on hook, strictly speaking, rank is that 9 grades hog on hook belongs to off standard among the present invention.Each other code of level also can use other symbols according to actual needs among the present invention.Table 7 is exactly the hog on hook level index table among the present invention, shown in table 7 is specific as follows:
Table 7 hog on hook level index table
| Rank | The total value scope |
| 1 | Total value 〉=150 |
| 2 | 140≤total value＜150 |
| 3 | 120≤total value＜140 |
| 4 | 100≤total value＜120 |
| 5 | 80≤total value＜100 |
| 6 | 60≤total value＜80 |
| 7 | 40≤total value＜60 |
| 8 | 20≤total value＜40 |
| 9 | Total value＜20 |
In the hog on hook level index table of the present invention, each rank of hog on hook is shown in first tabulation, secondary series is represented the total value scope of hog on hook, hog on hook among the present invention through choosing carcass operation, system trunk operation, weighing and measuring the fat operation, survey the muscle operation and survey tail fat operation just to obtain a total value, uses total value to inquire about the corresponding level that hog on hook level index table among the present invention just can obtain hog on hook then.
Because the hog on hook rank of total value＜20 just is 9 grades among the present invention, and the total value among the present invention is obtained by weight fat thickness value, muscle plumpness value and the value addition of tail fat degree.By table 5---hog on hook muscle plumpness concordance list muscle plumpness value as can be known is 10 to the maximum, by table 6---hog on hook tail fat degree concordance list tail fat degree value as can be known is 0 to the maximum, that is to say that the muscle plumpness value among the present invention and the summation of tail fat degree value are 10 to the maximum.This shows that in case the weight fat thickness value of hog on hook is, the rank of this hog on hook must be 9 grades, is 0 in case that is to say weight fat thickness value at 0 o'clock, then this hog on hook is an off standard just.---interior ternary hog on hook weight fat thickness matrix table and table 4---outer ternary hog on hook weight fat thickness matrix table is as can be known and by table 3, when the heavyweight of hog on hook to be fractionated and/or back-fat thickness level were " nothing " among the present invention, the corresponding weight fat thickness of this hog on hook value was " 0 " just.The rank of this hog on hook this shows, in case when the heavyweight of hog on hook to be fractionated and/or back-fat thickness level were " nothing ", must be 9 grades.
And by table 1---hog on hook weight hierarchy index table as can be known, when the hog on hook weight＜22kg among the present invention or hog on hook weight 〉=50kg, the heavyweight of this hog on hook is " nothing "; By table 2---hog on hook back-fat thickness hierarchy index table as can be known, when the back-fat thickness≤6mm of hog on hook among the present invention or back-fat thickness＞50mm, the back-fat thickness level of this hog on hook is " nothing ".The present invention is in practical operation in other words, in case when hog on hook weight＜22kg or hog on hook weight 〉=50kg, the rank of this hog on hook just is 9 grades; Perhaps when the back-fat thickness≤6mm of hog on hook or back-fat thickness＞50mm, the rank of this hog on hook just is 9 grades.This just makes the present invention can simplify in practical operation, as weighing and measure in the fat operation, when hog on hook is weighed, in case when hog on hook weight＜22kg or hog on hook weight 〉=50kg of the present invention, the rank of this hog on hook is 9 grades just, need not to carry out following other operation; If the weight＜50kg of 22kg≤hog on hook during then again to the hog on hook amount of carrying out back-fat thickness value, in case when the back-fat thickness≤6mm of hog on hook or back-fat thickness＞50mm, the rank of this hog on hook is 9 grades just, need not to carry out following other operation.Certainly, the order that takes by weighing hog on hook weight step and measure between the hog on hook back-fat thickness step among the present invention can be determined according to actual conditions, in a single day occurring heavyweight among the two is the situation of " nothing " for " nothing " or back-fat thickness level, then the classification of this hog on hook finishes, and the rank of determining this hog on hook is 9 grades, be off standard, the hog on hook of off standard generally is not applied in the pork processing technology.
Through top analysis as can be known, if the hog on hook that classification obtains is non-off standard, weight＜the 50kg of the 22kg≤hog on hook of this hog on hook and 6mm＜back-fat thickness≤50mm then, such hog on hook can better meet in other the processing technology, can more effectively improve the quality of pork product.If being 9 grades off standard hog on hook, the use rank processes, because the weight of this hog on hook is too light or weight is too heavy or back-fat thickness is too thick or back-fat thickness is too thin, this brings bigger difficulty not only for the processing of pork, and influences the quality of pork product.Pork processing enterprise also seldom can purchase the hog on hook of hog on hook weight＜22kg or hog on hook weight 〉=50kg or back-fat thickness≤6mm or back-fat thickness＞50mm in practical operation.This shows, among the present invention the weight＜50kg of the 22kg≤hog on hook of hog on hook and the rank of the hog on hook beyond 6mm＜back-fat thickness≤50mm are divided into 9 grades, not only made things convenient for the operation among the present invention, improved classification efficiency, and the processing of pork and the production of meat products had bigger help, also help the sound development of live pig pig industry.
Obtained the corresponding level of hog on hook after the present invention's process carcass grading operation, entered then and beat rank chapter operation, beaten rank chapter operation and cover corresponding rank chapter at the pig buttocks exactly, the rank chapter operation of beating among the present invention is a prior art.
