Abstract: Automatic estrus detection in cows is an essential component of modern livestock management.Efficient estrus detection methods can shorten the calving interval,reduce breeding costs,and increase reproductive efficiency.Traditional manual estrus detection is time-consuming and labor-intensive,and is no longer suitable for large-scale farming.Automated systems are the inevitable trend for estrus detection in the future.However,there are no mature automated identification systems for cows in slient estrus.Heart rate and respiratory rate are basic physiological indicators of cows,and the sexual excitement of estrus cows may cause changes in their heart rate and respiratory rate.Therefore,automated monitoring of heart rate and respiratory rate of estrus cows may become a new direction for estrus detection in the future.The author reviews the types of automated estrus detection systems for cows,introduces their related technical principles and achievements,compares the detection indicators and advantages and disadvantages of different estrus detection systems,and prospects the application prospects of new indicators for estrus detection monitoring in the future,providing a reference for related research.
