[The effect of a diet enriched with vitamin E on selected hematological and biochemical indicators in chickens].

The influence of the Czechoslovak developmental preparation of vitamin E, added to the feeding mixture in loose form (40 mg . kg-1) for the broiler-type chickens (from the 1st day after hatching to the 49th day of age), on the red blood count, peroxidase haemolysis of erythrocytes and on the activities of glutamate-oxalacetate transaminase (AST) and glutamate-pyruvale transminase (ALT) was studied. The results were compared with those achieved with chickens administered the same dose of the so far used vitamin E in the oil form, Soviet-made preparation and the Swiss-made preparation Rovimix E, and with the group of chickens fed the diets containing no vitamin E.

[Relation between glycemia, serum ascorbic acid, and weight gains in calves in large barns].

In the period from acceptance to the large-scale calf-house to six months of age, 42 calves (20 bullocks and 22 heifers) were studied for the dependence between the dynamics of glycaemia, ascorbaemia, and weights and weight gains. In both sexes, the highest level of glycaemia was obtained at the age from 14 to 21 days (kappa = 5.3 mmol.
