Abstract

Some aspects of culling pattern in different genetic groups of crossbred cattle, viz. 4 halfbreds of Hariana with Holstein-Friesian (FH), Brown Swiss (BH), Jersey (JH) and Red Dane (RH), and 5 three-fourths of 2 exotic breeds (FBH, BFR, FJH, JFH and FRH) were studied with the help of survival function,
hazard function and median survival time. A linear decline in survival rates with increasing order of lactation was observed. The differences in survival rates were sharper among halfbreds than in three-fourths. The median survival time and hazard functions for different groups of cows indicated the same trend. Results indicated the better stability of almost all the halfbreds except Red Dane than three-fourths. The survival distribution culling patterns of all the halfbreds were statistically different from the three-fourths.
