摘要/Abstract

摘要： 母牛发情鉴定是现代化养殖管理中不可或缺的一环,高效的发情鉴定方法可缩短母牛产犊间隔,减少饲养成本,提高繁殖效率。传统人工发情鉴定费时、费力,已无法满足规模化养殖需求,自动化系统是未来发情鉴定必然趋势,但是对于安静发情牛尚无成熟的自动化鉴定系统。心率和呼吸频率是母牛基础生理指标,发情母牛性兴奋可能会引起心率和呼吸频率的改变,发情牛心率和呼吸频率自动化监测或将成为未来母牛发情鉴定的新方向。作者综述了母牛自动化发情鉴定系统种类,介绍了相关技术原理和成果,比较了不同发情鉴定系统的检测指标及优缺点,展望了未来母牛发情鉴定监测新指标方法的应用前景,以期为相关研究提供参考。

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.

Key words: cows; automation; estrus detection; heart rate; respiratory rate; slient estrus
