Question

Shape of ovaries in swine is:

• A. Almond shape
• B. Egg shape
• C. Bean shape
• D. like cluster of grapes

Hint:

Remember these classic ovarian shapes for exams:
- Mare $\rightarrow$ Bean/Kidney-shaped (with an ovulation fossa).
- Cow/Ewe $\rightarrow$ Almond-shaped.
- Sow/Bitch $\rightarrow$ Cluster of grapes/Lobulated.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The morphological appearance of mammalian ovaries varies significantly across different domesticated species due to differences in litter size, follicular development, and anatomical structures.

Step 2: Detailed Explanation:
Let us review the ovarian morphology of various domestic animals:
- Swine (Sows): Swine are polytocous (litter-bearing) animals that ovulate many oocytes during each estrous cycle.
Consequently, numerous large follicles and corpora lutea develop simultaneously and protrude prominently from the ovarian surface.
This gives the ovary a distinctive lobulated appearance resembling a cluster of grapes.
- Cattle (Cows) Sheep (Ewes): Ovaries are typically oval or almond-shaped.
- Horses (Mares): Ovaries are uniquely kidney-shaped or bean-shaped due to the presence of a distinct ovulation fossa where all ovulations occur.
- Poultry (Hens): Have a single left ovary that also looks like a cluster of grapes, but this consists of massive, yolk-filled follicles at various stages of development.

Step 3: Final Answer:
Thus, the shape of ovaries in swine is described as looking like a cluster of grapes.
