Poultry Judging Practice Test

Pectoral Muscles account for what percentage of a bird's total weight?

1. 5-10 percent

2. 10-15 percent

3. 15-20 percent

4. 20-25 percent

The correct answer is: 15-20 percent

Pectoral muscles are critical for the flight capabilities of birds, constituting a significant portion of their muscular system. In many bird species, these muscles account for approximately 15-20 percent of the total body weight. This percentage may vary slightly depending on the species and other factors such as age and physical condition, but the range provided is generally accepted in poultry science. Understanding this percentage is important for those involved in poultry judging as it helps in evaluating the overall muscle development and health of the bird. A well-developed pectoral muscle system is indicative of a bird that is not only capable of flight but also physically fit. Recognizing this criterion can play a crucial role in assessing birds in both breeding scenarios and competitive environments.
