Infrared technology for estrus detection and as a predictor of time of ovulation in dairy cows in a pasture-based system.

Abstract

The development and application of an algorithm to assess the ability of an infrared thermography (IRT) device to predict cows in estrus and about to ovulate was investigated. Twenty cows were synchronized using a controlled internal drug release and PGF2α. Vulval and muzzle temperatures were measured every 12 hours from controlled internal drug release… (More)
