| Abstract | ||
| The study was carried out in two locations, first the breeding and improvement station of sheep and goats of the General Authority for Agricultural Research / Ministry of Agriculture (in Akkurov area 25 km west of Baghdad) and second outside the station of one of the sheep breeders (private sector) In some milk components of Awassi ewes. 120 Awassi ewes used to study the effect of breeding system in the milk components : protein, fat, ash , lactose , solids non-fatty and milk density. Through comparison between the breeding herds the results show a significant effect (p<0.01) shepherd herd compared with others at first analysis of the milk in the ash percentage (0.955, 0.905, 0.900) and a shepherd herd record highest percentage of solids non-fatty as it was (11.46, 11.03, 10.97) for the three herds respectively (improve herd , non-improved herd, shepherd herd), Also recorded milk density shepherd herd (p<0.01 ) highest density among the three herds (41.09, 37.51, 36.83) and show a significant effect (p<0.01 ) shepherd herd in the second analysis of the density of milk (37.91, 36.05, 34.84), the fat percentage has improved herd scored highest percentage fat analysis (8.18, 6.91, 4.77) in the second analysis of milk. When a comparison between the first and second analysis and through statistical analysis results showing superiority the shepherd herd of the second analysis on the first analysis in ash content (0.955, 0.906) and the proportion of non-fatty solids (11.46, 11.00).The density outperforming second analysis on the first analysis in improved herd (36.83, 34.84) and the herd is non-improved (37.51, 36.05) and shepherd herd (41.09, 37.91) and outperformed the results of the first analysis of the results of the second analysis in the percentage of fat for improved herd (8.18, 5.92) and the herd is non-improved (6.91, 4.69) and the shepherd herd (4.77, 2.59). | ||
