Studies on the level of some trace elements in cattle sera at different governorates [electronic resource].

Includes references.

Two hundred and fifty field blood and serum samples were aseptically and randomly collected from young pastured beef cattle located at different private farms in five governorates (Aswan, Minufiya, Al-Fayoum, Matrouh and Alexandria) during winter season. Green berseem that constitutes the main constituent of diet was also collected at the same time from these locations, in which the animals grazed. Blood, sera and berscem samples were subjected to biochemical analysis for trace elements. Haemogram was also done for these calves. The results provided that the level of trace elements in berseem and blood sera of calves varies between the different districts which gave a remarkable and valuable information about the effect this alteration on blood picture and animal health. This may serve as. a useful reference measure in treatment of different immunological, reproductive, and early growth problems that occur due to nutritional imbalance in these regions.
