Abstract | This study was designed to determine the roles of sex chromatin in relation to some blood and milk constitutes of she camel (Camelus dromedaries). Blood and milk samples were collected from 30 adult dairy, 5-10 years old she camel at Al Muthanna province during the period from August 2017 to February 2018.The samples were sent to the laboratory of college of veterinary medicine/ Kerbala University for analysis. The percentages of sex chromatin types including Drum stick, Sessile nodule, small club and Tear drop were 59.95%, 25.20%, 8.53%, and 6.31% respectively. The means of horizontal and vertical dimension and sex chromatin areaswere 1.150 ± 0.04 μm, 1.115 ± 0.04 μm and 0.986 ± 0.07 μm2 respectively. While, the average ± standard error of horizontal and vertical dimension and nucleus areawere 11.55 ± 0.29 μm, 11.12 ± 0.30 μm and 101.40 ± 4.76 μm2 respectively. Moreover, the sexual chromatin area / nucleus area and the number of lobes in the nucleus were 1.061 ± 0.07% and 3.82 ± 0.14 respectively. The blood glucose, total protein, total cholesterol, and total triglyceride means were118.89 ± 2.74 mg / dL, 7. 61 ± 0.18 g/dL and 70.80 ± 2.14 mg/dl and 55.28 ± 1.27 mg/dl, respectively. However, the lipid, protein, lactose and non-lipid solid materialsmeans of the milk were3.40 ± 0.11 and 3.60 ± 0.10 and 4.8 ± 0.12 and 11. 25 ± 0.17% respectively.A significant variations were appeared between different parameters of blood and milk constituents in relation to the types of sex chromatin. In conclusion, this study approved the possibility for using sex chromatin in rapid selection programs to improve the genetic properties in the local Iraqi camels population.
