Correlation of parity and age to services per conception, conception rate, and gestation length in Holstein Friesian cross cows

Abstract

0.05) between the parity with S/C, CR, and GL and the age with CR and GL. The only significant correlation (p <0.05) was between the age and S/C. Regression of S/C based on age followed the equation S/C = 0.104 + 0.407*age, with a correlation coefficient and determination coefficient of 0.733 and 0.538, respectively. It could be concluded that S/C could be predicted based on the age of the cows.
