Studies on the behaviour of suckler cows and their calves after birth

The behaviour of cows in a large beef suckler herd, comprising more than 600 heifers and cows, was observed in relation to their newborn calves. 89.6% of cows began caring for their calves, by licking, within 10 minutes of the birth. The intensity of care varied dependent on the breed and age of the cow Cows were moved to calving boxes at the point of parturition. A high degree of excitement was observed in 3% of cows. This was followed by active care of the calves. Additional mothering signs included stimulating calves to stand and help in finding the udder. There was a difference in the degree of these signs dependent on breed and age. A proportion of cows, notably Aberdeen Angus were aggressive to humans and their own calves. These signs were considered to be a sign of stress or other negative environmental influences. Signs of vitality were observed by 95% of calves within 9 minutes of birth. Calves born to cows started sucking after an average of 135 minutes and for those born to heifers after 143 minutes after their birth. Dystocia resulted in delayed signs of vitality The stud), indicated the need for special care of cows around the time of parturition, to reduce the loss of calves as a result of behaviour deficits. Heifers need special attention.
