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.
