Poultry Judging Practice Test

Pectoral Muscles in birds account for what percentage of their total weight?

1. 10-15 percent

2. 15-20 percent

3. 20-25 percent

4. 25-30 percent

The correct answer is: 15-20 percent

The pectoral muscles in birds are critical for flight, comprising a significant portion of their total body weight. Generally, these muscles account for about 15-20 percent of a bird's total weight. This range reflects the high reliance on these muscles for activities such as flapping and maneuvering in the air, which is particularly important for species that are strong fliers. The proportion of muscle mass dedicated to the pectoral region varies slightly among different bird species, influenced by factors such as size, activity level, and ecological niche. Understanding this percentage helps in assessing the physical fitness and capabilities of birds, especially in a poultry judging context.
