Comparative assessment of sire evaluation by incorporating auxiliary traits for estimation of breeding values of first lactation traits in Tharparkar cattle

Author(s): Garima Choudhary, U Pannu and GC Gahlot
Abstract: This research was aimed to estimate the breeding values of the sires using First lactation data of 91 Tharparkar dairy cows from 10 sires by using auxiliary traits along with the milk yield of daughter's. The average breeding value of sires was 1615.51, 1527.47, 1610.65, 1527.50 and 1580.47 when AFC, FSP, FCI, FDP and FLL respectively used as auxiliary trait along with the milk yield. The error variance was highest when AFC was used as auxiliary trait and error variance was lowest when FDP was used as auxiliary trait along with first lactation milk yield. Higher rank correlation (0.98 to 1) among all the traits when used as auxiliary trait indicated that there was higher degree of similarity of ranking of the sires by using all the traits as auxiliary trait along with milk yield for sire evaluation.
