* Both ovaries are enclosed within a fold of the mesosalpinx known as the ovarian bursa, the apex of this bursa forms a large circular orifice within which lies the fimbriae of the oviduct.

* Their general appearance and size varies according to the age and activity of the animal. ** In the prepubertal animals they have a smooth and glistening surface with several raised small vesicles (2 - 5 mm in diameter) throughout the surface which correspond to the [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicles]].

** In anoestrous females the [[Female_Reproductive_Tract_-The_Ovary_-_Anatomy_%26_Physiologyovaries]] are oval or circular, flattened laterally and have an irregular surface due to many small [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicles]].

** During the breeding season, mature [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicles]] and current [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|corpora lutea]] (CL) project from the main contour of the [[Female_Reproductive_Tract_-The_Ovary_-_Anatomy_%26_Physiology|ovary]] and give it a more lobular form.

*** This lobulation increases with increased number of previous [[The_Ovary_-_Ovulation_-_Anatomy_%26_Physiology|ovulations]] or pregnancies and is due mainly to the presence of old [[The_Ovary_-Corpus_Albicans|corpora albicantia]].
