Detection instrument and method for cow oestrus degree and optimum insemination time

Abstract

The invention discloses a detection instrument and method for the cow oestrus degree and the optimum insemination time, and relates to the technical field of cow reproduction. The detection instrument comprises a PWM wave generator, a direct-current constant-current source, a microcontroller, a two-way analog switch, a probe electrode and a display device. When measurement is conducted, the PWM wave generator generates PWM waves to control on-off of the two-way analog switch, direct-current constant-current currents generated by the direct-current constant-current source are converted into same-frequency measuring currents, the measuring currents act on the probe electrode to measure a bioelectrical impedance value of mucus around the probe electrode, the bioelectrical impedance value is input into the microcontroller, the microcontroller determines a cow oestrus degree and insemination time program according to fix quantities stored in the microcontroller, and then the current oestrus degree of a cow and whether the current time is the optimum insemination time of the cow or not are determined. Accordingly, labor force and labor intensity which are needed by traditional cow oestrus degree and insemination time detection are reduced, and the economic benefit of a livestock farm is increased.

Description

technical field [0001] The invention relates to a detection instrument for quantitatively determining the degree of estrus and the best insemination time of dairy cows, which belongs to the technical field of modern high-efficiency agricultural dairy cow reproduction and is used for quantitatively determining the degree of estrus and the best insemination time of cows. Background technique [0002] Accurate and efficient detection of estrus degree and optimal insemination time of dairy cows is a key link in cattle production and breeding, which is directly related to the improvement of reproductive capacity and economic benefits of cattle farms. Insufficient estrus identification of dairy cows will increase the number of missing cows in the herd, resulting in prolonged calving intervals, increased feed costs, and reduced reproductive capacity and economic benefits of dairy farms. Therefore, timely detection of estrus cows, correct grasp of the best breeding time, and reducin...

Problems solved by technology

However, the traditional detection method is time-consuming, labor-intensive and expensive, and requires employees to have rich experience and keen observation skills. It can only be used for small-scale cattle breeding, and is not suitable for larger-scale and intensive cattle farms.

However, domestic and foreign digital detection methods for cow estrus can only qualitatively determine whether a cow is in estrus. The degree of estrus and the best insemination time after cow estrus still need manual observation, and there is no quantitative determination of the degree of estrus and the best insemination the disadvantage of time
