Which physical feature can suggest a high growth potential in a market hog?

The broad back in a market hog is an important indicator of high growth potential due to its association with a greater muscle mass and overall body capacity. Hogs that have a broad and well-muscled back are generally better able to store muscle tissue, which contributes to increased weight gain and the production of quality meat cuts. A broad back also allows for more efficient feed conversion, meaning the hog can utilize feed more effectively to gain weight. Additionally, this physical characteristic is often linked to the desirable traits that meat processors look for, making such animals more valuable in the market.

In contrast, short legs may suggest an inability to develop a proper stance, which can impede mobility and overall growth. A thick neck might indicate strength but does not directly correlate with the efficient muscle accumulation necessary for high growth rates. Small ears do not provide a reliable measure of growth potential and may even indicate undesirable traits depending on the breed standards. In summary, a broad back is a clear sign of an animal's potential for growth and desirable muscle development.
