Abstract:
The performance recorded of 566 Triple cross (Phule Triveni) daughters of 53 sires maintained during the year 1972 to 2013 at Research Cum-Development Project on Cattle, Mahatma Phule Krishi Vidyapeeth, Rahuri were used to evaluate sires for first lactation and life time traits and to compare the effectiveness of multiple trait animal models over single trait models. The average least squares mean of first lactation were FL300DMY 2377.17±36.51 kg, FLPMY 11.55±0.65 kg, FLL 316.19±2.43 days, FCI 366.27±3.67 days, CAFS 105.69±5.79 days, IFLS 52.18±1.90 days and CACO 105.69±5.79 days. The effect period of calving had significant effect on FL300DMY, FLPMY, FLL and IFLS and non-significant effect on FCI, CAFS and CACO. Season of calving and age at first calving group had non-significant effect on all first lactation production and reproduction traits. The sire had significant effect on FL300DMY, FLPMY, FLL and CAFS and non-significant effect on FCI, IFLS, and CACO.
