Take the cow as an example: When the cow is not in heat, the data is above 300 After entering the estrus period, the data will drop below 300, and the lowest can drop to about 160. It lasts for a day or so, and then the data is opened, and when it rises to 250-300, it enters the ovulation period and can be bred. As long as the cows have signs of heat, the data will definitely be below 300, and most of them will be below 250. After a few hours of monitoring, you can control the value changes and determine the best mating time. 1 xCowsEstrousDetector
