The aimed of the current research to compare a biochemical constituent in ovarian follicular fluids of Iraqi one-humped she-camels (Camelus dromedarius) during the autumn, winter and spring in different follicles size of the ovaries. Classified in to, follicles sized 2-5 mm considered as small follicles (SF), 5–9 mm considered as medium follicles (MF) and 10–19 mm considered as large follicles (LF) were harvested from 107 adult female camels from the slaughterhouse. A Study was conducted during the period from 1/10/2016 to 1/7/2017. Results showed that there was decreased significantly (P<0.05) in total protein in (LF) in spring and in (SF) in autumn when comparative with other seasons, also decreased in (SF) on spring while increased significantly (P<0.05) in (SF) on winter when comparative with other follicles size. Cholesterol increased significantly (P<0.01) in (SF) on spring and in (LF) on winter, while decreased in (MF) on autumn when comparative with other seasons, also increased in (SF) on spring and in (LF) on winter when comparative with other follicles size. Glucose increased significantly (P<0.05) in (SF) and in (MF) but decreased in (LF) on winter when comparative with other seasons, while increased significantly (P<0.05) in (SF) on winter, also increased in (LF) on autumn when comparative with another size of follicles. Results showed that there were significant differences (P<0.01) and (P˂0.05), in total protein, cholesterol, and glucose in different size follicles and in different seasons (autumn, winter, and spring) of a study.
