Example Embodiment

[0018] The following is further described in detail by specific embodiments:

[0019] The example is basically as attached figure 1 Shown: a sow estrus management method, including the following steps:

[0020] S1. Monitor the body surface temperature and nighttime exercise of the target sow. Basal body temperature and basal nighttime exercise were obtained from the body surface temperature and nighttime exercise of the target sow from the day of weaning to the expected estrus day;

[0021] S2. From the estimated estrus day, obtain the periodic average body temperature according to the monitored body surface temperature, and obtain the periodic nighttime exercise amount according to the monitored nighttime exercise amount;

[0022] S3. Compare the average body temperature and basal body temperature on and after the expected estrus day to determine whether the body surface temperature of the target sow continues to rise and has a falling inflection point. Make a comparison t...

Abstract

The invention relates to the technical field of sow management. In order to solve the problem that in the prior art, a body surface temperature measurement mode is adopted to identify whether sows are in oestrus or not, so that the accuracy of an identification result is low, the sow oestrus management method comprises the following steps that S1, the body surface temperature and the night exercise amount are monitored, and the basic body temperature and the basic night exercise amount are obtained according to the body surface temperature and the night exercise amount; s2, starting from the predicted estrus day, according to the monitored body surface temperature and the night exercise amount, the periodic average body temperature and the periodic night exercise amount are obtained; s3, judging whether the body temperature continuously rises and a decline inflection point appears or not, and whether the amount of exercise at night rises or not; and S4, when it is judged that the body surface temperature continuously rises, a declining inflection point appears, and meanwhile, the night exercise amount rises, whether the current period is in a predicted estrus period or not is judged, if yes, estrus early warning is sent, and if not, manual intervention early warning is sent.

Description

technical field [0001] The invention relates to the technical field of sow management, in particular to a sow estrus management method. Background technique [0002] Since the normal reproduction of sows mainly depends on the accurate detection of estrus and timely breeding, timely and accurate estrus identification and timely breeding are crucial to reducing the empty pregnancy rate of sows and improving the reproductive efficiency of sows. The traditional detection method in production usually uses boar lure, and when lure, press the back of the sow to see if there is a static reflex, so as to judge the estrus. This method is not only cumbersome to operate and has a large workload, but also requires higher technical level and experience of the staff in order to ensure higher accuracy. [0003] A series of physiological and behavioral changes will occur when a sow is in heat. Therefore, in recent years with the rapid development of artificial intelligence technology and th...
