Poultry Judging Practice Test

The rupture of the follicular membrane during normal ovulation occurs at the stigma. This specific area is located on the surface of the ovary, where the follicle is attached. When the follicle matures, it creates a bulge on the ovary’s surface, and the stigma is the point where the rupture takes place, allowing the ovum to be released. This process is crucial because it prevents hemorrhaging and the resultant blood spots that could appear in the egg. Proper ovulation is vital for the development of healthy eggs, which is important in poultry production.

In contrast, the ovary is the overall organ where the follicles are housed, the infundibulum is the part of the oviduct where the ovum is captured after being released, and the uterus is where eggs are later formed into their final shape and shell. None of these locations functions in the same way to prevent bleeding at the moment of ovulation like the stigma does.
