Temporal trends in reproductive performance in Irish dairy herds and associated risk factors

Temporal trends in reproductive performance in Irish dairy herds and associated risk factors

Irish Veterinary Journal 57(3): 158-166

Irish dairy herd fertility has been declining since the 1980s. The extent, nature and causes of this decline in fertility and the current status of Irish dairy herd fertility were described. An increase in calving interval of approximately one day per year has been recorded. The principal components of this trend have been an increased incidence of postpartum endocrinopathies, reduced expression of oestrus and a fall in conception rate.
