    abstract = {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.}
