| Abstract | ||
| The incidence of sex chromatin and it's various shapes in polymorph nuclear leucocytes (PMNL) was investigated in Iraqi cows (Sharabi). A total of 72 animals were included in the study (15 heifers and 57 adult cows, both fertile and those suffering from reproductive problems). Results indicated, that sex chromatin incidence in Sharabi heifers (6 month old) was 6.9% distributed in 4 shapes (Drumstick 2.64%, Small club 0.28%, Tear drop 1.42, Sessile nodule 2.57%). In the fertile adult cows (4-6 years old) the incidence was 8.7% which was significantly (P < 0.05) higher than in heifers, distributed in 4 shapes: Drumstick 4.1%, small club 0.5, Tear drop 0.9, Sessile nodule 3.2%. The % of Drumstick and sessile nodule was significantly (P < 0.05) higher than in heifers. Concerning infertile animals the incidence of sex chromatin decreased significantly (P < 0.05) in animals suffering from abortion, still birth & repeat breeder than the fertile animals. The distribution of various shapes of sex chromatin also decreased significantly in all these animals as compared to fertile animals.
