Precision phenotyping of reproductive events in dairy cattle under heat stress: epidemiological validity and implications for genetic improvement in tropical systems.

Abstract excerpt

Heat stress in tropical and subtropical dairy systems invariably affects fertility because it reduces the rate of conception and increases the calving period. Although traditional visual techniques of reproductive event detection are insensitive and subject to errors, precision livestock farming (PLF) technologies such as accelerometers, rumination sensors, infrared thermography, and in-line progesterone assays...
