Abstract | The study was conducted on 218 caprine ovaries belonging to 109 Iraqi local goats that have been slaughtered in the Al-Shulla and Al-Bayaa regions in Baghdad,Iraq during the period from February 2016 to July 2016. The ovaries collected from 3-5 years old animals were divided into three groups according to the follicles size (small:< 3 mm, medium: 3-5 mm and large: 5> mm). The results showed significant differences (p<0.05) in the glucose for the medium follicle (MF) and large follicle (LF) groups as compared with a small follicle group (SF). The total protein of SF group was significantly (p<0.05) excelled other groups, while cholesterol levels showed the significant differences (p<0.05) among all groups. The calcium and magnesium concentration in MF and LF groups was significantly (P <0.05) higher compared to the SF group. On the contrary, the potassium in SM group was significantly (p<0.05) higher than the concentration in MF and LF groups. The concentration of estrogen and progesterone hormones shown significant differences (P <0.05) in the MF and LF as compared with the SF group, while the differences in the testosterone were not significant among the different groups. In conclusion: the changes in the metabolites concentration (total protein and cholesterol) and ions concentration (calcium and magnesium) as well as hormones concentration (estrogen and progesterone) could be associated with the size of the follicle in goats.
