Method for grading skinned pig half carcass

Abstract

The invention relates to a method for grading skinned pig half carcass, in particular to a method for grading skinned pig half carcass in three-way cross pigs. The method for grading pig carcass with good grading effect is not available at present. The method comprises the following procedures: selecting and preparing carcass, and the invention is characterized in that the method further comprises the following procedures: weighing carcass and fat, measuring flesh, measuring tail fat and grading carcass, wherein, in the procedure of selecting and preparing carcass, the weight grade index table is inquired by the weight value to acquire the weight grade, the back fat thickness grade index table is inquired by the back fat thickness value to acquire the back fat thickness grade, and the weight and fat thickness matrix table is inquired by the weight grade and the back fat thickness grade to acquire the weight-fat thickness value; in the procedure of measuring flesh, the flesh plumpness index table is inquired by the plumpness to acquire the flesh plumpness value; and in the procedure of measuring tail fat, the tail fat plumpness index table is inquired by the tail fat plumpness to acquire the tail fat plumpness value. The invention has the advantages of convenient gradation, simple procedures, low gradation cost, good effect, high accuracy and broad market outlook.

Description

technical field [0001] The invention relates to a method for grading pig carcasses with skin slices, in particular to a method for grading pig carcasses with skin slices in ternary pigs, which belongs to a method for grading pork and is mainly used for internal ternary pigs bred in China Pork grading of pigs and externary pigs. Background technique [0002] Pig carcass grading means that in order to meet the market's demand for high lean meat percentage, it is required to divide pig carcasses into different categories according to certain standards based on some economic characteristics of pig carcasses, such as carcass lean meat percentage and carcass weight. level. And connect different grades of pig carcasses with different market purchase prices, so as to stimulate the development of the pig industry and pig slaughtering industry, and guide the purchase and processing of pig farmers and meat production and processing enterprises. [0003] The purpose of pig carcass gra...

Problems solved by technology

When foreign intelligent grading equipment simulates the lean meat rate prediction equation and data model, it must first conduct a comprehensive investigation of different breeds of pigs according to the characteristics of Chinese commercial pigs, and then establish a large number of simulated lean meat rate prediction equations and data models, so as to establish The prediction model conforms to the national conditions of our country, but due to the special conditions of our country, the cost of establishing a large number of simulated lean meat rate prediction equations and data models will far exceed the instrument itself, which greatly increases the workload and increases the production cost

[0016] Also have some comparatively general pork grading methods at present, as open day is on March 29, 2006, and publication number is in the Chinese patent of CN1751812, discloses a kind of division method of pork color quality grade, and this method collects fresh meat by digital camera photos, and then intelligently graded by computer to determine the quality grade of pork. This method judges the grade of pork only by the color of pork, which makes the grading effect poor. Moreover, this method uses a digital camera to collect photos of fresh meat, so that The color of the photo collected by the camera will be different from the actual color of the pork, which will greatly affect the accuracy of the method

[0017] To sum up, there is no method for grading pig carcasses with good grading effect and wide application, especially there is no method for grading pig carcasses of inner three-yuan pigs and outer three-yuan pigs bred in China, so that The grading of pork is not accurate enough, which greatly reduces the utilization rate of pork, making it difficult to realize the model of price based on quality in pork trading, which has a great negative impact on pork production, especially the production of high-quality pork , making the development of the pig industry have greater resistance
