This study was conducted to compare some productive traits of imported versus locally bred and crossbred dairy cows (50, 56.5 and 62.5%) in 2 different farms in Khartoum, Sudan. The correlations between milk yield and lactation length for the 1st 3 lactations for Butana farm and the university farm were found to be 0.669 and 0.746, respectively. However, the correlation between total and 100 days mil yield for the 1st three lactations were found to be 0.762 and 0.746 for Butana and the university far, respectively. As for the breed effects, the 100 days milk yield were found to be 2156.6±599, 1566.67±383, 894.7±352.01, 732.76±1711.1 and 888.03±331.96 kg for imported Holstein-Friesian, locally born Holstein-Friesian, 50, 56 and 62.5% Friesian blood, respectively. |

This study was conducted to compare some productive traits (overall milk yield; 100 days milk yield; lactation length) and the effect of season of calving and parity number on imported versus locally bred and cross bred (50, 56.5 and 62.5%) in 2 different farms in Khartoum, Sudan. The results indicated a highly significant effect of breed in terms of 100 days milk yield; however, season of calving and parity showed insignificant effect in both farms examined. The lactation length impact on 100 days milk yield is significant at p< 0.01 between purebred and cross ones. |
