Genetic and non-genetic factors affecting pre-weaning (PMY), post-weaning (AMY), total milk 
yield(TMY), lactation period (LAP), peak milk yield (PKY) and time to peak (TPK) were 
investigated. Results revealed that there was no significant effect of does age and sex by litter 
size on all studied traits. Season of kidding had a significant effect (P<0.01) on AMY, TMY, 
LAP and TPK. Does coat color was significantly (P<0.05) affected PMY. No differences 
between horned and polled does were found in milk traits. Regression of PMY on doe weight at 
kidding was highly significant and being 1.22 kg/kg. Correlation coefficients among milk traits 
were all positive and ranged between 0.05 and 0.78.
