Abstract
The present study was undertaken to study the seasonal, diurnal, and sex-wise distribution of calving between crossbred and Tharparkar cows (Bos indicus) under tropical conditions. The retrospective detail analysis of calving pattern/trend in different times, day, night, season and sex-wise distribution were analyzed for the past four years (May 2017 to March 2021) covering 701 calving of crossbred cattle and 183 calving of Tharparkar cattle. No significant associations were observed in male and female calving patterns of crossbred and Tharparkar cattle (X2=1.015a, p>0.05). The calving distribution revealed a significantly strong association with the season. Crossbred cattle showed maximum calving in winter and rainy while Bos indicus calved maximum in the summer season (X2=41.702a p<0.001). A similarly strong association was found between the distribution of calving in four 6-h periods during the 00.00-24.00 h with time in both crossbred and Tharparkar cattle. Further, significantly higher calving percentages were reported in the night hour than the day hour in both the breeds with 51%crossbred cattle and 53% in Tharparkar cattle calved during night time. The percentage of the calvings occurred during the 24 hours and their hourly distribution throughout the 24-h period was found fairly uniform.
