A device for improving sow reproduction

Abstract

The invention discloses a device for improving sow reproduction, which comprises a pulse condition sensor, a body temperature sensor, an MCU processing unit, an electromagnetic device, a communication module, and a power supply module. The processing unit outputs a pulse current synchronized with the pulse beating time and transmits it to the electromagnetic device. The electromagnetic device converts the pulse current into a corresponding pulsed magnetic field and acts around the sow's genitals. The pulsed magnetic field adjusts the blood flow speed of the sow, enhances metabolism, and accelerates tissue Repair and restore physiological functions, and then induce estrus in sows. The body temperature sensor detects the body temperature of the sow and transmits it to the MCU processing unit. The MCU processing unit analyzes and compares the received body temperature data. When the body temperature data exceeds the preset value, the communication module is activated to send the sow estrus information to the staff. The invention integrates the two functions of estrus promotion and estrus detection, and can maximize the conception of sows.

Description

technical field [0001] The invention belongs to the technical field of animal feeding, in particular to a device for improving the reproduction of sows. Background technique [0002] In large-scale farms, an important part of sow feeding is how to make sows pregnant. Only when pregnant can there be piglets and reproduction. The key to making the sow pregnant is to make the sow go into estrus and find the sow to go into estrus in time and perform mating. [0003] In the case of intensive and large-scale feeding, due to the limitation of the living space of sows and the lack of sexual stimulation, the phenomenon of sow anestrus is more serious. At present, sow estrus is mainly carried out by manual intervention. The estrus control technology uses hormone injection to induce estrus. The defect of this method is that after a long period of continuous injection of hormones, the pig itself will become dependent on the hormone, which will affect the normal natural estrus performan...

Problems solved by technology

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

Vaginal inspection is to use a vaginal speculum to observe changes in the vaginal mucous membrane, secretions, and cervix to determine whether there is estrus. When sows are in estrus, they often miss the best mating period and can only serve as an auxiliary identification
