Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] A cattle estrus early warning method records and judges the changes in the cattle body activity through the data of the cattle body activity, so as to warn the situation of the cattle estrus.

[0019] Specifically, when collecting cattle physical activity, when the increase in the cattle physical activity at any collection time point is higher than 2.5 times the average historical cattle physical activity at the same collection time point in the previous 7 days, the duration of the increase in activity The time is not less than 1 hour, and there is at least one peak, which is an early warning of cattle estrus. Regarding the peak of the bovine body activity, that is...

Abstract

The present invention provides a cattle estrus early warning method, which collects cattle body activity and cattle body temperature, and when the rise of the cattle body activity at any collection time point is higher than the average historical cattle body activity at the same collection time point in the previous 7 days 2.5 times the amount of bovine body activity, and the duration of the increase in the amount of bovine physical activity is not less than 1 hour, and there is at least one peak, which is an early warning of estrus; further, when the body temperature at any collection time point is higher than that at the same collection time point in the previous 7 days The average body temperature is 0.3°C higher, and the duration is not less than 4.5 hours, which can further improve the accuracy of early warning of cattle estrus. Combining the two detection methods for estrus detection can solve these shortcomings. Therefore, the cattle estrus early warning method of the present invention can effectively improve the detection rate and accuracy of cattle estrus, and has important application value.

Description

technical field [0001] The invention relates to the field of animal husbandry, and more specifically, to a method for early warning of estrus in cattle. Background technique [0002] Cattle activity refers to the measurement of all behavioral activities of cattle, such as daily feeding, lying down, rumination, and exercise. The activity monitoring system developed according to the characteristics of cattle activity changes plays an important role in cattle breeding management. However, not all cattle have obvious estrus performance, and about 10% of the cattle have no obvious estrus performance, so it is very difficult to observe estrus only manually. Although the detection rate of commercial estrus monitoring equipment is as high as 95%, the detection rate of recessive estrus cattle with no obvious estrus performance is lower than 70%, and the detection rate of estrus monitoring still needs to be further improved (Cao Xuehao et al., 2013). The reasons for the low detection...
