Poultry Judging Practice Test

How long is the chicken oviduct in an egg-producing hen?

1. 65 centimeters

2. 78 centimeters

3. 85 centimeters

4. 90 centimeters

The correct answer is: 78 centimeters

The chicken oviduct in an egg-producing hen is about 78 centimeters in length. This elongated structure plays a vital role in the reproductive system of the hen, as it is responsible for the transport of the ovum from the ovary, along with the formation of the egg components such as the egg white and shell membranes, before the egg is finally laid. The length of the oviduct is significant because it allows for the sequential development of the egg as it passes through different regions. Each section of the oviduct contributes to the formation of specific parts of the egg, such as the infundibulum, magnum, isthmus, and uterus. A well-functioning oviduct that is of this length ensures that the hen can efficiently produce eggs on a regular basis, supporting the reproductive cycle and overall health of the bird. Understanding the dimensions of the oviduct and its function is important for those studying poultry science or involved in poultry production, as it directly relates to egg production capabilities.
