Poultry Judging Practice Test

In broilers, the pectoral muscles account for what percentage of the bird's total weight?

1. 5-10%

2. 10-15%

3. 15-25%

4. 25-35%

The correct answer is: 15-25%

The pectoral muscles, commonly known as the breast muscles, are one of the most significant components of a broiler's body. In broilers, these muscles are highly developed because they are responsible for the bird’s ability to produce the rapid movement required for flight in wild counterparts, though domesticated broilers are typically bred for rapid growth and heavier body weight. When considering the total weight of a broiler, it is established that the pectoral muscles comprise approximately 15-25% of the total body weight. This range reflects the emphasis on muscle development in broilers due to selective breeding practices aimed at enhancing meat yield. Thus, identifying the correct percentage of the pectoral muscles in broilers is vital for assessing meat quality, overall growth performance, and making informed decisions in poultry production and judging.
