What is a common effect of copper deficiency in sheep?

Copper deficiency in sheep can lead to significant health issues, primarily resulting in anemia and poor growth. Copper plays a critical role in the formation of hemoglobin, which is essential for transporting oxygen in the blood. When sheep lack sufficient copper, they may experience a reduced capacity to form red blood cells, leading to anemia, which is characterized by fatigue, weakness, and an overall decline in health. Additionally, copper deficiency can impair growth rates as it affects various metabolic processes and the development of connective tissues and bones, inhibiting the sheep's ability to grow and thrive effectively.

In contrast, excessive wool production results from adequate nutritional support, particularly regarding minerals and vitamins, which copper deficiency hinders. Improved immune function is also linked to adequate copper levels, as the mineral is essential for the development and function of immune cells. Lastly, weight gain would not typically occur in sheep suffering from copper deficiency, as their growth and overall health are compromised under such conditions.
