Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0054]As described in the related background technology, the measurement of the growth performance of livestock is done by manual + equipment, relying on manual measurement of livestock at close range with the help of collection equipment, and the livestock need to be driven if necessary. However, artificial methods are prone to inaccurate data due to different manual experience and inconsistent measurement standards, and driving livestock may cause stress reactions in livestock, affecting t...

Abstract

The invention discloses a training method and device for a growth performance measurement model and a measurement method and device, and the method comprises the steps: obtaining a livestock pedigree table and a first individual feature of a livestock individual, and building a first adjacent matrix according to the livestock pedigree table; splicing the first adjacent matrix and the first individual features to obtain a first spliced feature, so as to combine the individual features of the livestock individuals with a genetic relationship, thereby combining the influence of the current own conditions and genetic factors of the livestock individuals on the growth performance; and finally, on the basis of taking the first splicing feature as model input, performing iterative training on a preset graph neural network model, and stopping iteration until the graph neural network model reaches a preset convergence condition to obtain a growth performance determination model, thereby realizing the determination of the livestock growth performance by using the neural network model. The problem that the determination result is inaccurate due to dependence on manpower is solved, meanwhile, the livestock does not need to be driven, and the stress reaction of the livestock is avoided.

Description

technical field [0001] The present application relates to the field of animal breeding, in particular to a training method, measurement method and device for a growth performance measurement model. Background technique [0002] The determination of livestock growth performance is of great significance to breeding and fattening, which can provide data basis for the genetic evaluation of individual livestock, the genetic evaluation of group economic traits, the evaluation of the production level of livestock groups, the formulation of breeding planning and the management of livestock farms. . [0003] At present, the measurement of the growth performance of livestock is done manually and equipment, relying on manual measurement of livestock at close range with the help of collection equipment, and the need to drive the livestock if necessary. However, artificial methods are prone to inaccurate data due to different manual experience and inconsistent measurement standards, and...
