Influence of circadian rhythm, breed, stage of lactation, milk yield and parity on body and udder skin surface temperature of lactating cows monitored by infrared thermography

The objective of the study was to establish baseline thermographic information on body and udder skin surface temperature (USST) lactating cows in different stages lactation, milk yield, parity, breed season. Holstein Friesian crossbred (n = 19 cows) Deoni 14 were monitored for (i.e. eye) USST prior milking using a forward looking infra-red (FLIR) camera. It observed that mean both did not differ significantly. breeds significantly higher by 0.9–1.0°C during evening than morning milking. There no difference between days quarters. Similarly, stage yield parity show any influence over USST. summer (1.1°C) spring winter seasons. had 1.0°C lesser cows. is concluded would be useful developing breed-specific signature individual animal.
