Verma, Nisha | Singh, V. K. | Singh, N. S.
First lactation milk yield per day of lactation length of 379 Sahiwal cows, collected from cattle breeding farm, Chak Ganjaria, Lucknow were utilized for the present study. The optimum number of progeny size to achieve the accuracy attained by different methods of sire evaluation (Daughter's average (DA), contemporary comparison (CC), Least-squares (LS), Simple Regressed Least-squares (SRLS) and Best linear unbiased prediction (BLUP» ranged from 47.615 (CC) to 161.069 (BLUP). Similar results were also obtained in the ratio ofoptimum progeny size estimated by different methods with that of actual progeny size per sire available ranging from 5.270 (CC) to 17.828 (BLUP). Present findings revealed that BLUP method showed highest increase in accuracy of 207.72% among all the methods studied.
