Dairy cow behaviour in relation to health, welfare and milking

摘要: Animal welfare includes both physiological and mental health is affected by several external internal factors. In dairy cows, human care the ability of cows to cope with daily challenges are most significant The research presented in this dissertation focused on cow behaviour aspects impacting behavioural changes during mastitis milking. To deepen knowledge relationship between associated detection methods, we experimentally manipulated status through induction. Moreover, tested validated a thermal infrared camera for recording udder skin temperature, which could be helpful case early detection. Furthermore, examined milking herringbone automatic systems. We established that changed mastitis. apparent were lying, eating stepping behaviour. It was shown inflammation status, priorities. contrast our expectations, visual signs milk composition occurred only 2 hours post-challenge, while clinical first recorded 4 post-challenge. However, lying restlessness behaviours promising indicators detecting exposed transient increase body temperature experimentally-induced successfully detected help camera. rose simultaneously rectal temperature. local inflammatory udder, appearing earlier than increase, not measurement using Regarding as an indicator success quality process, found half deviations occurring originated from behaviour, such kicking, lifting their legs moving milking, had origins machine failures. conclude, can used (un)successful effectively functioning human-animaltechnology interactions should studied more future order enhance husbandry practices improve animal welfare.
