Abstract:

The research data spread over a period of 41 years (1974 to 2015) were utilized to study the heritability, genetic and phenotypic correlation of life time performance traits. The mixed model analysing using LSML were used for estimation of variance components considering sire as a random effect, season and period of birth and age at first calving groups as fixed effects. Period of birth was highly significant on LTMY3, LTMY4, ALTMY, HL and PL whereas non-significant on BE. Season of birth did not influence any of the trait considered in the study. Age at first calving group had non-significant effect expect PL. The sire had significant effect on HL and PL and non-significant effect on LTMY3, LTMY4, ALTMY and BE. The overall least squares means of life time traits were 8770.95 149 kg (LTMY3), 12127.85 233 kg (LTMY4), 14920.46 525.16 kg (ALTMY), 2771.78 52.26 (HL), 1688.59 52.05 (PL) days and 82.62 0.83 (BE %), respectively. Heritability estimates of LTMY3, LTMY4 and ALTMY were (0.23 0.13; 0.29 0.10 and 0.17 0.43). Whereas the heritability estimates for HL, PL and BE (0.23 0.14, 0.14 0.13 and 0.06 0.11). The heritability estimates of lifetime traits had low to medium magnitude indicating that these traits can be improved through selection. While low heritability of BE indicating that this trait was influenced to a greater extent by non-genetic causes and can be improved through better management. The genetic and phenotypic correlations of LTMY3 and LTMY4 with other lifetime traits were high and positive.
