Description
Technical Field
The invention belongs to the technical fields of intelligent breeding, intelligent equipment and the Internet of things, and particularly relates to a sow optimal mating time detection device and a sow optimal mating time detection method.
Background
Under the modern large-scale sow breeding condition, the average conception rate of sows bred by adopting an artificial insemination mode is greatly improved to about 92%, and the average conception rate of non-modern large-scale farms is far lower than the average conception rate. Even in modern farms, 8% of sows were not successfully bred, and the sows with unsuccessful breeding were found at the earliest in the next estrus (after 21 days), and some were found even later. Unsuccessful mating can significantly increase the cost of cultivation time, feeding costs, and management costs.
The sow can be successfully bred, the breeding time is a very critical factor, and only the sow with oestrus has higher conception rate. The average estrus cycle of the sow is about 21 days, each estrus lasts for 3 to 5 days, and the estrus cycle comprises three stages of estrus early stage, estrus middle stage and estrus later stage, and the sow in the estrus early stage shows excitation anxiety, does not stop calling and climbs other pigs, but does not accept other pigs to climb; mid-oestrus manifests as arousal, anorexia, and onset of acceptance of other sow climbs, the most important of which is: standing reflection (the sow on the back is stationary after being pressed by a hand for manual detection) appears, and the standing reflection is an important index that the sow can be bred; later estrus is manifested as calm, enjoying lying down, normal appetite, refusal to climb, and disappearance of static reflex. From the occurrence of the static reflection to the disappearance of the static reflection, the period lasts about 1 day, and the current industry-accepted comparatively stable mating scheme is as follows: after the occurrence of the standing reflection, the first seed matching is carried out at 8 hours, the second seed matching is carried out, and if the seed matching process is abnormal (bleeding, backflow and the like), the third seed matching is carried out at 8 hours.
Meanwhile, the body temperature of sows in oestrus can rise by 1 to 2 ℃, but the current condition is not usually used for judging oestrus of sows, because the artificial perception of the body temperature change of 1 to 2 ℃ is difficult, the error is large, and the artificial collection of continuous body temperatures of a plurality of sows is not practical.
At present, the optimal hybridization time of sow mainly comprises the following modes:
1. manual checking: at present, the optimal breeding time of sow inspection mainly depends on manual inspection, and all sows which enter the proper age and reach the weight standard are subjected to primary estrus and optimal breeding time detection in the large-scale pig farm every morning and afternoon. The manual detection has larger stress on pigs, the detection accuracy is highly dependent on experience of detection personnel, the granularity of the detection time is larger, and the best mating time is easily missed.
2. Determination using sow ovulation test equipment: the following problems are found in the measurement of the use of sow electronic ovulation test equipment: the problems of pig infection diseases, limited precision, delayed discovery time and the like caused by frequent entry of foreign matters into pigs due to the fact that animals are not matched with the pigs to be injured.
3. Boar try the condition: the boar test condition is used as an auxiliary means for detecting oestrus and optimal mating time, and the biological safety problem that the boar frequently contacts with the sow still needs to be manually verified as a detection result.
