What is a potential consequence of overfeeding sheep?

Overfeeding sheep can lead to obesity and metabolic disorders, which is a significant concern in sheep management. When sheep consume more nutrients than they require, their bodies store excess energy as fat. This can result in obesity, which in turn can predispose the animals to various health issues such as laminitis, fatty liver syndrome, and other metabolic disorders like pregnancy toxemia. These conditions can have serious repercussions for the sheep's overall health, productivity, and welfare.

The other options do not correctly reflect the impact of overfeeding. Increased wool production and improved health are typically associated with balanced nutrition, rather than excessive feeding. Excess food does not necessarily translate into better health or production levels. Additionally, weight loss would typically result from underfeeding or poor nutrition rather than overfeeding, making it not applicable to the context of this question.
