Data on production
performance of 200 animals maintained at University Livestock
Farm, Kerala Agricultural University, Mannuthy and Cattle
Breeding Farm, Thumburmuzhi were used for the study. Among the
eight economically important traits [305 day milk yield, fat
percentage, protein percentage, SNF(Solids not fat), total
solids, peak yield, days to attain peak yield and AFC(Age at
first calving)], milk fat percentage and AFC had significant
difference among the families. The families of Deva, Bull No.250
and Hakkim showed significantly lower milk fat percentage
compared to the other seven families. The AFC of the families of
Dipesh, Onkar and Gopal was significantly higher from the other
seven sire families.
