[Age-related dynamics of blood biochemical indices in Black Pied calves]

The level of a number of blood indices was followed up in Black-and-white calves from the first day after birth up to the sixth month such as hemoglobin, 2,3-diphosphoglycerate, blood sugar, phosphorus, and total, ionized, and protein-bound calcium, with total protein. The calves were clinically normal and were raised in various regions under routinely adopted zoohygiene, technologic, and microclimatic conditions and parameters, and were offered rations that were currently adopted in this country. The dynamic established with the changes of the indices investigated disclosed possibilities of obtaining additional information concerning the state of the animal's organism which proved instrumental in choosing the right prophylaxis in compliance of the respective age period.
