Evaluation of hematological and metabolic parameters in small ruminants with trace elements deficiency under different biogeochemical conditions

Abstract

In the present study soil, water, pasture plants, organs and tissues of crossbred sheep of the Soviet Aksaray and Zaanen German White Improved goats were analyzed for their Selenium (Se), Iodine (I), Cobalt (Co), zinc, copper, and manganese content in the Lower Volga region. The biogeochemical situation of terrestrial ecosystems of the Lower Volga region was characterized by Se, Co, and I deficiencies in soil, water, pasture plants, and feed of crossbred sheep of the Soviet Aksaray and Zaanen German White Improved goats. The deficiency of these trace elements in small ruminants had been compensated by changes in hematological parameters include high Red Blood Cell (RBC) and White Blood Cell (WBC) and biochemical parameters. Meanwhile, the analyzed trace elements in the organs and tissues of crossbred sheep (n = 6) and Zaanen German white improved goats (n = 6) demonstrated that goats had lower amounts of Se (0.0136 ± 0.002 mg/kg), I (0.19 ± 0.01mg/kg), and Co (0619 ± 0.03 mg/kg) compared to sheep. The animals were recorded with a decrease in alkali reserve, the content of total protein and lipids, vitamins A, E, C, B12, total calcium, and inorganic phosphorus, increase in glucose, conjugated dienes and malonic di-aldehyde in the blood, and functional insufficiency of the antioxidant protection system.
