Abstract
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.
