Effect of season on blood minerals in Iraqi bull buffalo

الملخص EN

The present study was conducted to investigate some aspects of the reproductive system in Iraqi bull buffaloes and the effects of seasonal changes on physiological parameters.

96 blood samples of buffalo’s bull were collected from the slaughter house during August 2013 to August 2014.

Blood samples were analyzed to study the effect of season on the blood minerals during the different seasons of the year.

The results of the minerals assays showed that there were no significant differences for (calcium, phosphorus, and sodium) which increased in autumn and winter, decreased in spring and summer.

The calcium recorded (2.39, 2.41, 2.22, 2.51) m.Mol/L, the phosphorus (2.19, 2.18, 1.99, 1.92) m.Mol / L, and the sodium (140.78, 140.66, 140.33, 139.16) m.Mol / L in autumn, winter, spring, and summer respectively, while the results showed significant differences (p <0.05) of copper reading during the different seasons which recorded a highest level in autumn and winter (68.63, 67.7, 64.15, 54.56) m.Mol / L.
