ABSTRACT

Data of 432 lactation records of 96 crossbreds cows sired by 5 bulls extending over a period 1980-
1997 from Cattle Breeding Farm, Borgaon Manju, Akola (M. S.) were collected. The first lactation
traits are first lactation milk yield (FLMY) and first lactation length (FLL) while lifetime traits are
lifetime milk yield (LTMY) and productive life (PL). Best linear unbiased prediction (BLUP) and
Least Square (LS) was used to estimate sires breeding values and the model included sire as random
effect, season and period of calving as fixed effect. The FLMY showed very high and significant rank
correlation with FLL (0.99) and LTMY (0.99) by BLUP. The product moment correlation of FLMY
with FLL and LTMY were also high and significant by BLUP. The rank correlation of FLMY with
LTMY and PL is high and significant by LS methods also. The high positive and significant rank
correlation and product moment correlation between FLMY and LTMY indicated that sire can be
selected on the basis of FLMY for improvement in LTMY.
