A method for grading and adjusting the precise nutrition foraging deviation of live pigs

Abstract

The application provides a method for precise nutrition foraging deviation grading and correction of live pigs, and belongs to the technical field of precise nutrition feeding of live pigs. The technical scheme is as follows: current and historical state data of target live pigs are acquired, the state before correction, the corrected actual foraging amount and the stable state set are determined; the foraging deviation, the factor contribution and the unexplained residual error are determined according to the above, the age-based nutrition arrearage state is updated and the deviation level is determined; the correction action and the target factor are determined according to the deviation level, the factor contribution, the nutrition arrearage state and the action response elasticity; the correction action is executed, the posterior non-correction trajectory is generated, the factor contribution drift of the non-target path is deducted, the correction net response is obtained, the action response elasticity and the distributed response kernel are updated, and the correction maintenance period is determined. The application has the beneficial effects that the closed-loop cooperation of foraging deviation identification, nutrition arrearage evaluation, action selection and response updating is realized, and the accuracy and adaptability of individual nutrition correction are improved.
