Hourly distribution of time of parturition in beef cows



Hourly distribution of time of parturition in beef cows



Canadian Journal of Animal Science 62(2): 597-605



Data on year of calving, sex of calf, age of cow, weight of cow, calf birth weight and breed from 1151 calving records, collected over a 4-yr period at the Agriculture Canada Research Station, Brandon, Manitoba, were analysed. The hourly distribution of calvings was relatively uniform over the 24-h period. Slightly more calves were born from 07.00 to 19.00 h (51.5%) than between 19.00 and 07.00 h.
