Summary: | The present investigation was undertaken to study the effect of non-genetic factors, viz., service
period (SP), dry period (DP) and gestation period (GP) on various milk production traits in Kankrej
cattle. 1235 lactation records (2nd-7th) of 475 Kankrej cows, progeny of 75 bulls that were maintained
at University Livestock Research Station, Sardarkrushinagar (Gujarat), calved during 1980-2014,
were studied. The effects of service period (111.64 ± 52.55 days) and dry period (143.17±28.78
days) on total lactation milk yield (2089.45±582.38 kg),305 days milk yield (2045.66±531.92 kg)
and lactation length (282.90±49.46 days) were highly significant (pis less than 0.01), while the effect of
gestation period (288.86±7.14 days) was non-significant on all these production traits. Cows which
took more time to conceive after parturition produced more milk with longer lactation length |
