Abstract

A method for monitoring abnormal conditions of cows in estrus relates to the field of animal husbandry, and aims to solve the problems of poor reliability and time-consuming and laborious monitoring of abnormal conditions of cows at present. The invention utilizes sensors distributed at different positions of the bovine body to collect the physiological data of cows in estrus in real time, and then realizes the monitoring of abnormal conditions of cows in estrus through comparison with standard data. The invention has good real-time monitoring and saves time and effort. .

Description

Method for monitoring abnormal conditions of cows in estrus

Technical Field

The present invention relates to the field of livestock husbandry.

Background

Oestrus cycle of cows

In the process of breeding cattle, the breeding of cattle is an indispensable part. When the cow reaches sexual maturity, a series of sexual activity phenomena, namely oestrus, can occur periodically. When a cow is in estrus, mucosal congestion, red swelling and viscous liquid discharge of the reproductive tract are mainly shown, the cow is excited by abnormal spirit, the cow gradually receives climbing of other cows, follicles in ovaries develop to maturity, and the cow starts to ovulate. The stage in which cows collectively exhibit the characteristics of estrus is called estrus in production, and the period from the start of one estrus to the start of the next estrus is defined as one estrus cycle.

Duration of oestrus in cows. The period of time from when the cow begins to accept the crawl of other cows to when the crawl of other cows is refused is defined as the time during which the cow is in heat. The heat duration of the cows is different due to different varieties, reproductive performance, individual difference and the like, the holding time is also different and can be different from 6 to 36 hours, the length of each cow can reach 48 hours, and the average time is 18 hours. As the duration of the oestrus time of the cow is short, the cow oestrus is needed to be done, and the reduction of the mating conception rate of the cow caused by missing the oestrus time and the optimal mating time of the cow is avoided.

The abnormal conditions of the cows in estrus include strong resistance to crawling and crossing, running and the like.

In order to obtain the mating conception rate of cows, abnormal condition monitoring is required for cows in estrus.

At present, abnormal condition monitoring is carried out on the heat cows, the abnormal condition monitoring is still stopped in an original manual watching type visual observation mode, the reliability is poor, and the monitoring is time-consuming and labor-consuming.

Disclosure of Invention

The invention provides a method for monitoring abnormal conditions of cows in estrus, aiming at solving the problems of poor reliability and time and labor consumption in the conventional abnormal condition monitoring of cows.

The abnormal condition monitoring method for the cows in estrus is characterized by comprising the following steps: it comprises the following steps:

step one, standard database establishment steps, which specifically comprise:

step one, selecting a period of time T with stable cow state in the estrus period of the cow; sequentially executing the first step and the second step to the first step and the sixth step;

step two, respectively monitoring the cattle abdomen vibration data Z1 and the cattle back vibration data Z2 in a time period T by adopting vibration sensors arranged on the cattle abdomen and the cattle back;

step three, storing the cattle body abdomen vibration data Z1 and the cattle back vibration data Z2 collected in the step two as cattle body abdomen standard vibration data in the estrus period of the cows and cattle back vibration data in the estrus period of the cows into a cow breeding monitoring server;

step four, respectively adopting four acceleration sensors arranged on the brackets, and respectively collecting acceleration data of the four brackets;

step five, averaging the acceleration data of the four corbels collected in the step three, taking the average as the acceleration data of the standard corbels of the cow in estrus, and storing the acceleration data into a cow breeding monitoring server;

step six, executing step two;

step two, under the condition of no on-duty personnel, repeatedly executing the steps from one to six in the step one; then, executing the step three;

thirdly, comparing the acquired data with corresponding standard data of estrus respectively by the cow breeding monitoring server, judging whether the difference value is within a preset range, and executing a fourth step if the judgment result is yes; if the judgment result is negative, executing the step five;

step four, judging that the estrus cow is normal, finishing the current monitoring, returning to the step two, and carrying out the next monitoring;

step five, judging that the estrus cow is abnormal, finishing the current monitoring, returning to the step two, and carrying out the next monitoring;

the invention has the following beneficial effects and remarkable progress: according to the invention, the physiological data of the cows in estrus are collected in real time by using the sensors distributed at different positions of the cow body, and then the abnormal condition of the cows in estrus is monitored by comparing the physiological data with the standard data.

Detailed Description

The specific implementation mode one, the estrus cow abnormal condition monitoring method, its characteristic is: it comprises the following steps:

step one, standard database establishment steps, which specifically comprise:

step six, executing step two;

in this embodiment, the vibrations data at ox body belly vibrations data and back are used for reflecting whether the cow produces the conflict to "lying prone of bull striding", and when the cow produced the conflict to "lying prone of bull striding", the cow can swing the health with the conditioned reflex ground in order to break away from "lying prone of bull striding", consequently produces the vibrations data at ox body belly vibrations data and back, judges through the vibrations data of gathering ox body belly vibrations data and back whether the estrus cow condition is unusual.

And step five, after the cow is monitored to be abnormal, warning information is sent to farm management personnel by adopting wireless communication equipment.

In the present embodiment, the acceleration sensor on the corbel is used to reflect whether the abnormal behavior of "breaking away", "jumping", or "escaping" occurs in the approaching or mating behavior of the cow. And judging whether the situations of the cows in estrus are abnormal or not by collecting acceleration data on the corbels.

Claims

1. A method for monitoring abnormal conditions of cows in estrus, which includes the following steps:

Step 1. Standard database establishment steps, specifically:

Step 11, in the estrus period of the cow, select a period of time T in which the cow is in a stable state; execute Steps 12 to 16 in turn;

Steps 1 and 2, using vibration sensors arranged on the belly of the cow and the back of the cow to monitor the vibration data Z1 of the belly of the cow and the vibration data Z2 of the back of the cow in the time period T respectively;
