Abstract
The present investigation was carried out to evaluate lifetime
production performance in terms of productive life (PL), herd life (HL),
total life (TL), life time milk yield (LTMY), milk yield per day of
productive life (MY/PL), milk yield per day of herd life (MY/HL) and milk
yield per day of total life (MY/TL) of Jersey crossbred cattle maintained at
PGRIAS, Kattupakkam, Tamil Nadu. The overall least squares means
standard errors were 886.06 ± 37.54 days, 1432.25 ± 49.21 days, 2684.96 ±
49.75 days, 4411.14 ± 194 kg.12, 4.96 ± 0.08 kg, 3.25 ± 0.14 kg and 1.53 ±
0.04 kg, respectively for PL, HL, TL, LTMY, MY/PL, MY/HL and
MY/TL. Heritability estimates for PL, HL, TL, LTMY, MYPL, MYHL and
MYTL were 0.044, 0.114, 0.085, 0.095, 0.073, 0.139, and 0.114
respectively. Performance of the Jersey crossbred herd was comparatively
lower in terms of lifetime production traits studied.
