Abstract

This study was carried out on some productive traits of two different crossbred dairy cows having 62.5% and 50% foreign blood at University of Khartoum farm, Sudan. The effect of lactation length on total milk yield was found to be highly significant (P <0.01). Effect of foreign blood percentage on total milk yield was found to be significant (P <0.05). Age at first calving had non-significant effect on total milk yield. The regression analysis of lactation length showed that there is non-significant effect of age at first calving and foreign blood percentage on lactation length. Crossbred dairy cows which have 62.5% Friesian blood performed better than 50% Friesian blood and secured advanced age at first calving.
