Which of the following can indicate poor nutrition in sheep?

A rough coat appearance is a clear indicator of poor nutrition in sheep. When sheep do not receive adequate nutrition, the condition of their fleece can deteriorate, leading to a coarser, more unkempt coat. Nutritional deficiencies can affect the production of lanolin and other essential oils that contribute to the health and appearance of the fleece. Additionally, a rough coat may signal other underlying health issues related to inadequate feed or imbalance in their diet, which can further impact their overall condition.

In contrast, improved fleece quality might suggest that the sheep are receiving proper nutrition. Increased aggression could be attributed to factors such as social dynamics or stress rather than nutritional status. Higher lambing rates are typically associated with good nutrition and overall flock health, so they wouldn't indicate poor nutrition. Thus, the rough coat appearance stands out as a direct and observable sign of nutritional inadequacies in sheep.
