Shape of Active Ovary in Poultry
The shape of the active ovary in poultry resembles:
- Bunch of grapes — Correct Answer
- Almond shape
- Bean shape
- Cauliflower shape
Explanation:
Correct Answer: Bunch of grapes
The active (functional) ovary in a laying hen resembles a bunch of grapes because of the numerous follicles (each containing a developing yolk) at various stages of maturation clustered together.
Ovarian Follicle Hierarchy
- A mature laying hen's ovary contains follicles at many stages: large yellow follicles (F1, F2, F3, F4, F5) and many smaller white follicles.
- F1 (largest, ~35 mm) is about to ovulate.
- One follicle ovulates approximately every 24–26 hours in a productive layer.
Comparison with Other Species
- Cattle ovary: Almond-shaped, smooth surface.
- Sheep/Goat ovary: Small, almond-shaped.
- Poultry ovary: Bunch of grapes (due to multiple visible surface follicles).
Why Other Options Are Wrong
- Almond shape → describes the ovary of cattle and small ruminants.
- Bean shape → not a standard description for any domestic species' ovary.
- Cauliflower shape → may describe pathological ovarian tumours; not the normal ovary.
