Sow breeding management method

Abstract

The invention discloses a sow mating management method. A manager only rechecks the physiological estrus characteristics of sows according to a signal prompt of an estrus checking lamp on an estrus detection processing device and can accurately judge whether each sow is in an estrus cycle in a form of saving observation labor and time; when each sow is determined to be in the estrus cycle, the manager performs mating operation according to the first and second prompts of a mating signal lamp, so that human faults or mistakes in a mating period are effectively avoided, and a pregnancy test can be automatically performed; during the mating and successful impregnation of each sow, a supervision center computer compares, analyzes and records each-stage expression data or information, obtained by the estrus detection processing device, of each sow in each estrus cycle or each mating, and outputs supervision data corrected before the next estrus cycle or the next mating to the estrus detection processing device for updating, so that the estrus cycle and mating success rate of each sow can be accurately controlled and improved along with the progressive increase of estrus frequency or mating frequency.

Description

technical field [0001] The invention relates to a sow mating process, which can significantly reduce the workload of human recording and analysis, and overcome the difference in estrus discrimination due to different experience values ​​of personnel, and can avoid mating mistakes and mistakes, and also has accurate estrus judgment, A breeding management method for sows capable of automatic pregnancy testing. Background technique [0002] Feeding sows and nurturing young pigs is an important task for maintaining production in pig farms. After the sow is sexually mature, under the action of a series of hormones, the follicle maturation and ovulation process in the ovary is called estrus regularly; the period from the last estrus ovulation to the next estrus ovulation is called the estrus cycle or sexual cycle . The average estrous cycle of sows is 21 days, and the duration of estrus is about 5 days. If there is no breeding or no breeding after estrus, estrus will occur repe...

AI Technical Summary

Problems solved by technology

[0006] Due to the duration of estrus of sows, it often varies with individuals, ages, and breeds; the current practice in breeding farms is to carefully observe and record in detail the estrus cycle of each sow (the number of days or hours in estrus period) by experienced managers. number), characterization (pattern or management), in order to correctly estimate the ovulation time and determine the insemination (mating) time; The estrus data of pigs is a heavy, complicated and extremely unscientific task; most of the cases where the ovulation date of sows are misjudged when the management personnel take over or the records are not detailed enough
