Brisket disease primarily affects which organ in cattle?

1. Kidneys

2. Liver

3. Heart

4. Lungs

The correct answer is: Heart

Brisket disease, also known as high-altitude disease or cor pulmonale, primarily affects the heart in cattle. This condition is typically associated with cattle that are brought to higher elevations abruptly, where the oxygen levels are lower. The decreased oxygen results in the heart having to work harder to pump blood efficiently throughout the body. As a consequence, the right side of the heart can become enlarged, and fluid may accumulate in the brisket area, giving it a swollen appearance, hence the name "brisket disease." The other organs can be affected by different diseases and conditions, but brisket disease specifically involves cardiac issues related to oxygen deprivation in high-altitude situations. The focus on the heart is critical for recognizing symptoms and implementing management practices to prevent or treat this condition in affected herds. Understanding this relationship helps livestock producers make informed decisions regarding animal health and welfare, especially in elevation-sensitive regions.
