Seasonal Influence on Hematology and Biochemical Blood Parameters inMongolian Domestic Sheep

Mongolian livestock are most exposed to cold and nutritional stress during the winter and spring.This study examines the seasonal variations in hematological and biochemical parameters, including cortisol hormone levels, in Mongolian domestic sheep.The results showed an increase in white blood cell count and a decrease in red blood cell count and hematocrit during winter and spring.Additionally, there were decreases in serum total protein, albumin, triglyceride, and calcium, along with significant increases in high-density lipoprotein, urea and cortisol concentrations in winter and spring compared to autumn.These fluctuations maintained a stable level of homeostasis, indicating that Mongolian domestic sheep possess a high biological ability to adapt to adverse influences such as ecosystem, climate, and pasture shortage.
