Assessment of Copper Deficiency and effected on Some haematological and biochemical in Lambs in Salah Al-Din City

Copper (Cu) is an essential trace element in ruminant nutrition, playing a crucial role in enzymatic functions, hematopoiesis, and connective tissue synthesis. Copper deficiency in sheep can be primary (due to low dietary intake) or secondary (resulting from antagonistic interactions with minerals such as iron, molybdenum, and sulfur), leading to impaired copper metabolism. This study was conducted in different areas of Salah al-Din city (Tikrit - Al-Alam - Samarra - Baiji) during the period from June 2 to October 15, 2024. (100) lambs were obtained, fifty of which were a control group, fifty subclinical lambs suffering from copper insufficiency, and the clinical group suffering from copper deficiency. from different areas of Salah al-Din city. The ages of the animals ranged from one month to two years and their weights ranged between (4-50) kgThe results showed a significant decrease in hemoglobin levels6.15±3.207 B , red blood cell count2.71±1.887 C , and ceruloplasmin activity 6.60±4.180 C , along with an increase in leukocyte counts8.20±2.201 B, indicating immune dysfunction. Additionally, This study highlights the importance of maintaining proper mineral balance in sheep nutrition to prevent copper deficiency-related health issues and enhance productivity.
