How many pounds of water should a lamb consume per day if it eats 3 pounds of feed?

Lambs typically require a significant amount of water relative to their feed intake. The general guideline is that for every pound of feed consumed, a lamb should drink approximately 2 to 3 pounds of water. Therefore, if a lamb is eating 3 pounds of feed, the expected water intake would range from about 6 to 9 pounds.

Option C, which suggests a water consumption of 6 to 15 pounds, aligns well with this guideline. It encompasses the minimum expected and accounts for other factors such as environmental conditions, activity level, and overall health, which may necessitate higher water intake as indicated by the upper limit. This ensures that the lamb remains properly hydrated and can effectively digest the feed it consumes.

In contrast, the other options either underrepresent or overly generalize the required water intake, making them less applicable for this scenario.
