A meat quality grading method and system for live animals without slaughter

Abstract

The invention relates to a meat quality grading method and system for live animals without slaughter. The method includes acquiring the body weight and three-dimensional image of the animal within the breeding time limit; obtaining the weight growth value of the animal according to the weight collection, and segmenting the breeding time limit according to the weight growth value to form multiple time periods; partitioning the animals according to the three-dimensional image to obtain The partition weight set of each partition; construct the feature value set at each acquisition time of the partition; divide the feature value into positive and reverse self-selection coefficients according to the set reference value corresponding to each feature value; according to the number of segments, feature values, Set the reference value, the total number of eigenvalues ​​in the forward self-selection coefficient set, the total number of eigenvalues ​​in the reverse self-selection coefficient set and the normalized value of the eigenvalues, and calculate the forward self-selection coefficient set and the reverse self-selection coefficient set The score value of the selection coefficient set; determine the grade of the meat quality of the partition according to the score value. The invention can grade the meat quality of animals without harming animals.

Description

technical field [0001] The invention relates to the field of animal meat quality grading, in particular to a meat quality grading method and system for live animals without slaughter. Background technique [0002] At present, the scale of animal breeding has grown and produced huge economic benefits. But the quality of animal meat on the market is complicated. For enterprises, the standard for purchasing animals from farmers is currently mainly based on animal weight. Enterprises purchase animals in the ideal weight range based on experience, but the meat quality of animals under this weight range is not necessarily optimal. Therefore, simply use The weight selection and acquisition of animals is not scientific enough, and it is easy to lose high-quality animals. [0003] For farmers, the weight range of live animals is limited, and animal weight control is carried out according to this range, so as to meet the corporate acquisition standards. In this case, however, optim...

Problems solved by technology

[0004] At present, in addition to the method of selecting animals based on body weight, there is also the detection of animal meat quality, but this method needs to cut and even slaughter the animals to measure the quality of meat, which will cause great harm to animals. kill animals that are being fed

Moreover, in the process of breeding high-quality animals, based on slaughtering to detect the improvement effect of animal meat quality, the loss of breeding samples will outweigh the gains.
