Abstract
This study was conducted on 424 ovaries (212 slaughter Iraqi ewes) in Al-Shulla and Al-Kut abattoirs during period from December2015 to November 2016, age of animals were 3-5years. We collected ovaries and divided to three groups of follicles included small follicles (SF) <2mm, medium follicles (MF) 2-5mm and large follicles (LF) ≥5mm in both ovaries. We divided the follicles into four groups according to seasons( autumn, winter, spring, summer). Results revealed in the right ovary the number of SF during winter were highly significant (P<0.05), more over the number of MF during winter and autumn were increase significant (P<0.05, and the number of LF recorded highly significant (P<0.05) at autumn. While in the left ovary the number of SF during winter were highly significant (P<0.05), while the number of MF during autumn and winter were highly significant (P<0.05), The number of LF during winter were highly significant (P<0.05). The number of SF in right ovary recorded increase significant (P<0.05) in winter as compared with left ovary, as well as the number of MF in the right ovary were highly significant (P<0.05) during winter as compared with left ovary and the numbers of LF in the right ovary during autumn were highly significant (P<0.05) as compared with left ovary. In conclusions from this study the activity of ovaries were included all seasons, and the activity in right ovary was better at autumn, while in left ovary was better activity in winter on Iraqi ewes.
