Bovine estrus disclosure method based on activity monitoring

Abstract

The invention discloses a bovine estrus disclosure method based on activity monitoring. The method comprises the following steps that 1, according to a period t, the bovine activity is obtained periodically; 2, according to the whole bovine estrus period, a long-term calculation period T1 is set, an activity expected value A1 and a mean square error D in the period t within the period T1 is calculated in a rolled mode; 3, according to the every bovine estrus duration time, a short-term calculation period Ts is set, and the activity expected value As in the period t within the period Ts is calculated in a rolling mode; 4, the deviation k between the long-term activity expected value and the short-term activity expected value As is calculated; 5, by comparing the deviation k with the estrus disclosure threshold value K, the bovine estrus is judged. The method is simple in algorithm and high in disclosure accuracy and can adjust the parameters according to experience.

Description

technical field [0001] The invention relates to the field of cattle estrus reporting methods, and in particular designs a cattle estrus reporting method based on activity monitoring. Background technique [0002] Reproduction is one of the key tasks in the dairy and beef cattle farming industry. The gestation period of a cow is 280 days, and usually one calf is born every year. For beef cattle farms, every additional calf produced means an additional cow's income in the same period of time. For dairy farms, the peak milk production period of dairy cows is 1 to 6 months after calving. After 6 months, both milk production and milk quality have dropped significantly, and economic benefits have turned negative. Dairy cows should be brought back as soon as possible. calving. Therefore, improving the reproductive rate of dairy cows and shortening the calving interval is of great significance for improving the economic benefits of beef and dairy cattle production.

However, the estrus reporting rate of the pedometer is generally not high, and generally does not exceed the estrus reporting rate of manual observation.
