Data for the present investigation was collected on 41 native black does at the Bakrajou farm, college of

Agriculture, University of Sulaimania during March-August 2002.During the pre-weaning period, milk yield

was recorded once a week by suckling technique and hand milking. After weaning (90 days) does were hand

milked till they dry off.Total milk yield averaged 136.78 ± 7.70 kg, the maximum daily yield (1800 gm/d)

attained at 8th week of lactation. The correlation coefficients between total milk yield and monthly yield were

all positive and significant, the range being 0.32-0.98. Linear multiple regression equation using maximum R-

square improvement between total milk yield and monthly yield was calculated.
