Embodiment 1

[0021] Estrus identification (estrus detection): the device moves twice a day, morning and evening, outside the railing next to the ewe pen to be tested, and stays outside each circle for 2-3 minutes, releases the smell containing ram sex hormones, and sends out ram courtship When the ewe sees the ram model, hears the ram’s courtship cry or smells the ram’s sex pheromone, it will actively approach the device, cling to the railing or stick its head out from the railing, and the distance measuring sensor 1 Measure the distance between the ewes and the device. When the distance between the ewes and the sensor receiving module is less than or equal to 0.6m, the PLC counts once; according to the distance between the sheep and the device and whether it is close to the device, the PLC combines the number of times the camera captures the tail, etc. Factors to determine whether the ewe is in estrus or not, wherein, if the frequency of tail wagging occurs more than once in 1 minute, the ...

Embodiment 2

[0024] Estrus induction: For ewes in the breeding period that have not yet started estrus or ewes that have not been in estrus for a long time after weaning, the device can be run on the channel of the breeding ewe house or weaning ewe house several times a day, through visual, auditory, Olfactory stimulation induces estrus, which is similar to the "ram effect", prompting ewes to go into estrus early. When the main purpose is to induce estrus, there is no need to take pictures and identify and record the number of sheep during the operation of the device, and there is no need to stay outside each sheep pen , to fast pass.

Embodiment 3

[0026] Comfort the ewes during insemination: When the staff artificially inseminate the ewes, it will inevitably cause stress to the ewes. The frightening and struggling of ewes is one of the factors leading to the low conception rate. However, if at the same time as the insemination, the test device emits the ram's courtship call or the special smell of the ram, then the ewe can produce a certain sense of pleasure and slow down the stress of artificial insemination on the ewe.

Abstract

The invention discloses a bionic ewe estrus detection/induction apparatus and an estrus detection/induction method; the apparatus comprises a ranging sensor, a central processing module, a wireless communication module, a recording device, a biological estrus induction device, an image acquisition device and a power source; the above parts are mounted on a base which is mounted on a wheeled travelling mechanism; in estrus detection/induction, the biological estrus induction device attracts an ewe in estrus, the ranging sensor measures a distance between the ewe and the apparatus, and the recording device records sound made by the ewe; the image acquisition device acquires the signals, such as ewe ear tag number, tail wag images, and pen number, and the central processing module judges whether the ewe is in estrus or not and transmits judging results and measurement information to a farm background management terminal. Estrus detection or induction is performed herein according to the principle of bionics, so that working quality and efficiency are improved; the apparatus and the method are convenient to operate and high in practicality, require reduced numbers of ewes and farm workers, and reduced feed cost, and may be used to induce estrus and comfort ewes during insemination, so that fertility rate and conception rate are increased.

Description

technical field [0001] The present invention relates to the estrus detection and seduction of ewes in a sheep farm, in particular to a estrus detection / eduction device for ewes based on the bionics principle, and also relates to a method for using the device to detect estrus / seduction for ewes. Background technique [0002] Large-scale sheep farms generally implement separate breeding of males and females, and ewe estrus identification (estrus check) is an important part of the breeding work of sheep farms. The purpose of estrus identification is to detect estrous ewes in time, correctly grasp the time of inbreeding or artificial insemination, prevent mismatching or missing mating, increase conception rate, and shorten breeding interval. The most commonly used method for estrus identification of sheep is the ram test method. The rams that are looking for estrous ewes and not used for mating are called test rams. During the test, tie a test cloth on the abdomen of the test r...
