Electromagnetic device for promoting estrus of cows

Abstract

The invention discloses an electromagnet device for promoting oestrus of cows. The device comprises a pulse acquisition module, an oestrum detection module, a controller, an electromagnetic device, acommunication module and a power supply module. The pulse acquisition module collects pulse beat information around cow genitals and sends the information collected to the controller. After the controller receives pulse information, pulse currents synchronized with pulse beat time are output and sent to the electromagnetic device. The electromagnetic device converts the pulse currents into a corresponding pulse magnetic field. The pulse magnetic field acts around the cow genitals, regulates the speed of blood flow in the cows, changes microcirculation, enhances metabolism, and accelerates tissue repair and recovery of physiological functions, thereby inducing the estrus of the cows. The estrus detection module detects the behavior that the cows are bestridden by bulls, and when a bestriding behavior occurs, the communication module is started to send cow estrus information to staffs. The device integrates the functions of promoting the estrus and detecting the estrus, and maximizes theprobability of cow conception.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and veterinary medicine, in particular to an electromagnetic device for promoting estrus in cows. Background technique [0002] In a large-scale farm, whether it is a beef cow or a dairy cow, one of the important contents of the cow feeding management is how to make the cow pregnant. Only when the cow is pregnant can there be a calf and reproduction. The key to make the cow pregnant is that the cow is in estrus and finds that the cow is in estrus in time for breeding. [0003] In the current situation of intensive and large-scale feeding, cow estrus is mainly carried out by manual intervention. The conventional technology of cow estrus regulation is to use hormone injection to induce estrus. After continuous injection of hormones for a long time, the cow itself will become dependent on the hormones, which will affect the normal natural estrus performance of the cows, cause damage to the ...

Problems solved by technology

The external observation method is mainly to manually observe the external performance of cows, such as cows climbing over other cows during estrus or accepting cows, congested and swollen vulva, moist vulva with transparent body fluid, tears, etc., according to the staff. Comprehensive analysis of the observed phenomenon to judge whether the cow is in heat or not, this method not only wastes manpower but also is prone to misjudgment

Vaginal examination is to use a vaginal speculum to observe changes in the vaginal mucous membrane, secretions and cervix to judge whether it is in estrus or not. This method is difficult to detect cows in estrus in time, and often misses the best mating period. It can only be used as an auxiliary identification effect
