Effect of deficiency of some minerals on phenotypic classification of anemia in Awassi sheep

Abstract

This study was prepared to detect anemia in Awassi sheep by identifying changes in some blood values, categorizing anemia phenotypically, and studying its effect on some trace minerals. 225 blood samples were taken From Awassi sheep reared on natural pastures in certain parts of the Salah al-Deen and Nineveh governorates. The ages of the animals ranged from 1 to 5 years, with 150 cases of many types of anemia and 75 healthy cases as a control group. The results of blood tests showed a significant decrease (P < 0.01) in the volume of packed blood cells (PCV), hemoglobin (HB), total number of red blood cells (RBC count), MCV, there was no significant difference in the concentration of hemoglobin (MCHC) between infected and healthy animals in microcytic normochromic anemia. In macrocytic normochromic anemia, the results showed a significant decrease (P < 0.01) in the size of PCV, hemoglobin HB, and the total number of red blood cells (RBC count), and a significant increase (P < 0.01) in the MCV and the amount of hemoglobin MCH, and there was no significant difference in Hemoglobin MCHC concentration between infected and healthy animals. In normocytic normochromic anemia, the results showed a significant decrease (P<0.01) in the volume of packed cells PCV, hemoglobin HB, and total number of red blood cells (RBC count), and there was no significant difference in the volume of MCV, the amount of hemoglobin MCH, and the concentration of hemoglobin MCHC between infected and healthy animals.

In macrocytic hypochromic anemia, the results showed a significant decrease (P<0.01) in the size of packed cells volum, hemoglobin, and the total number of red blood cells, and a significant increase in corpuscle size and the amount of hemoglobin, and a significant decrease (P<0.01) in the concentration of hemoglobin between infected and healthy animals. The results of biochemical tests showed a significant decrease (P < 0.01) in the concentration of total protein and minerals ( phosphorous (P), zinc (Zn), copper (Cu) and iron (Fe) in infected animals compared to the control group.
