[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.

[Blood picture of calves from primiparae kept under large-scale production conditions in the early postnatal period].

Twelve calves of the Red Spotted breed and its crossbreds born by first-calvers, kept in a large-capacity stable of a dairy farm, were subject to the study of the ontogenetic development of the values of the blood picture from birth up to the 10th day of age. The erythrocyte and leucocyte count, the packed cell volume and the relative and absolute number of neutrophils reached the significantly highest levels in calves before drinking the colostrum. The amount of haemoglobin, MCV and MCHC reached the highest values on the first day after birth.

[Blood picture of beagle dogs of Czechoslovak breeding].

In this paper the individual values of the blood picture were determined in 60 dogs of the beagle breed of the age of one to two years, of the live weight of 15-18 kg, of Czechoslovak breeding, which were used for experimental purposes. It was found that in the examined group of dogs the different hematological parameters did not almost differ from the findings stated in various literary sources and that they corresponded fully to the standard values for dogs.
