Effect of parity and season of calving on the calving interval in Retinta cattle



Effect of parity and season of calving on the calving interval in Retinta cattle



Investigacion Agraria, Produccion y Sanidad Animales 4(1): 45-51



Data on 461 calvings of 59 Retinta cows were analysed. Age at 1st calving averaged 3.25 yr and age at the last calving 11. 08 yr. Calving interval averaged 428+or-7 days, and was significantly affected by parity (ranging from 399.4 days for cows in their 5th parity to 465.4 and 464.6 days for cows in their 1st and 2nd parities resp.) and month of calving (shortest for cows calving in Dec. and longest for those calving in May).
