What condition does urinary calculi refer to in sheep?

Urinary calculi in sheep refers specifically to the formation of stones within the urinary tract, which can lead to urinary tract obstruction. This condition occurs when mineral deposits aggregate to form calculi that can obstruct the urinary passage, leading to difficulty in urination or even a complete blockage. The resultant urinary retention can cause significant pain, distress, and, if untreated, can ultimately be fatal for the animal.

The issue is particularly common in male sheep due to their unique anatomy, which predisposes them to blockages. The condition can be exacerbated by dietary imbalances, particularly those high in phosphorus and low in calcium, which promote the development of these stones.

Understanding this condition is crucial for effective management and prevention strategies in sheep husbandry, helping to ensure the overall health and productivity of the flock.
