Abstract
This study was conducted at the Animal Farm pertaining to the college of Agriculture, Qadisiyah University during the period from 18/11/2014 to 18/5/2015, The study included 30 goat does (10 Local ,10 Cyprian, 10 Afghan) with different ages and weights in order to investigate the effect of breed and non-genetic factors such as type of birth and sex of the kid in some productire characteristics (weekly , monthly and total milk production) and the chemical composition of milk (fat and protein) and results were as follows: - The genetic group had effect high significant( P<0.01) in characters of (weekly , monthly and total milk production , outperforming the local group which average ( gram 978.90 , Kg 27.42 , Kg 137.35 ) on cypriot group whose average ( gram 660.29 , Kg 19.90 , Kg 90.18 ) and Afghan group which average ( gram 834.04 , Kg 23.50 , Kg 116.58 ). The type of birth had effect high significantl ( P<0.01) in two characters of weekly , monthly and total milk production and singnificantly higher ( P < 0.05) in characters of monthly milk production, Outperforming mothers of twin births with out performed to mothers with individual births in all the studied traits ((weekly , monthly and total milk production )and their amounted averages were respectively ( gram 849.48 , Kg 240.77 , Kg 117.82 , gram 795.75 , Kg22.33 , Kg 111.14 ). The sex kid had a significant effect ( P < 0.05) in trait of weekly milk production, and there was no significant effect of the baby sex in two qualities the monthly and the totally of milk production by average of (Kg 23.70 , Kg 112.80 ) Respectively, Mothers of female births to mothers male births in trait of weekly milk production. The strain of the highly significant impacted ( P<0.01)on the proportion of fat in the milk , and there was no significant effect of strain on protein. There was highly significant effect ( P<0.01) on the proportion of fat in the milk, there was no significant effect on the type of birth on in the trait of Protein. Kid sex was highiy significant effect ( P<0.01) on the proportion of fat and Protein in the milk.
