[Normal values of the hematological, biochemical and enzymological indices of the donkey]. / Normalni stoinosti na niakoi khematologichni, biokhimichni i enzimologichni pokazateli pri margareto.

Studied were a total of 85 (33 male and 52 female) donkeys of the Martina Franca breed of the domestic ass, aged from one to twelve years. Stated are the results for the normal values of hemoglobin, hematocrit, ESR, total erythrocyte and leukocyte counts, leukocyte formula, blood sugar, cholesterin, urea, total protein and protein fractions, some micro- and macroelements, and enzymes as tabulated in four diagrams. No differences have been established with regard to sex. It has been found that with young animals the normal values of hemoglobin and erythrocytes are lower than with adult ones. With aging the total count of leukocytes shows a lowering trend, while the percent of neutrophiles rises. The lymphocyte profile of the white blood picture of this breed animals has been shown to be combined with eosinophilia. The amount of total protein with young donkeys is lower than with older ones, however, the albumin-globulin ratio remains unchanged. It is also stated that the concentration of inorganic phosphorus and calcium is in reverse correlation with the age of the animals--inorganic phosphorus is higher and calcium is lower in young animals, and vice versa. So far as the enzyme activity is concerned the values of the investigated enzymes are generally lower in donkeys than in horses.

[Changes in the blood coagulating properties of preserved blood and the native and lyophilized plasma of cattle during storage]. / Promeni v khemokoagulatzionnite svoistva na konservirana kruv, nativna i liofilizirana plazma ot goveda pri sukhraniavaneto im.

Studied were some of the indices characterizing the blood clotting system (thrombocytes, fibrinogen, recalcified clotting time, CA-thromboplastin time, kephalin-kaolin time, thrombin time. F II, and F V) in preserved glucose-citrate blood kept at 4 degrees C, in untreated bovine plasma kept at 20 degrees C, 4 degrees C, and -20 degrees C, and in freeze-dried bovine plasma. It was concluded that bovine blood preserved with L-12 could be used as a hemostatic agent up to the 10th day after it was obtained; untreated plasma could be used up to one month after it was obtained; and freeze-dried plasma could be used up to two months after it was obtained. Following freeze-drying the coagulation properties of the plasma remained active for more than a year, and it could also be used as a hemostatic agent.

[Total protein, sulfur and bound amino acid content in the hoof horn of cows]. / Sudurzhanie na obshtiia beltuk, siarata i svurzanite aminokiselini v kopitniia rog na kravi.

Comparative investigations were carried out for the evaluation of the total protein and sulfur in the sole hoof horn of cows of the breeds Bulgarian Brown and Black and White with normal and diseased hooves as well as of the bound amino acids in the hoof horn of the same hooves of cows of the Black and White breed. It was found that the total protein as indicated above did not show any essential differences in the two breeds. The amount of total sulfur in Bulgarian Brown cows was relatively higher than that in Black and White cows. It was also found that the lower content of sulfur in the diseased hooves indicated lower resistance. The content of bound amino acids in the hoof horn of Black and White cows with both normal and diseased hooves showed certain variations. Generally, it proved lower in diseased hooves of the hind limbs than in affected hooves of the forelimbs.
