Bisoniana LXXX. The hematology of the free-ranging European bison

Bisoniana XCIX. Serum biochemistry of free-ranging European bison

“…It seems, that the obtained hematological and biochemical parameters of serum (Wołk, 1983;Wołk & Józefczak, 1984 and this paper) may serve in monitoring the general health condition and nutritional status of bison. However, the diagnostic values of particular parameters demand further research and experiments.…”

“…Those animals were shot as a result of elimination of late-born calves, supernumerary and agressive ones and those of bad physical condition. Those were the same bison on which in 1980-1983 hematological research had been carried out (Wołk, 1983) and the research of serum proteins (Wołk & Józefczak, 1984) and also the bison shot in 1984. All the material taken into consideration in calculations comes from a winter period (November-March), which allows for omitting seasonal variation.…”

“…Likewise the increased inorganic phosphorus content of the young- The relationship between the level of serum biochemical indices and deseases discovered in some of the examined bison is difficult to establish. It is possible that it results, at least partly, from the fact that in many bison, despite the invasion of parasites, there exists some kind of physiological balance between a host organism and a degree of invasion, which was mentioned earlier (Wołk, 1983). Hence, the lack of correlation, for example, between the degree of invasion by Fasciola hepatica (Trematoda) and the level of such diagnostic indicators of liver deseases as ALP, bilirubin, SGOT etc.…”

“…There are no appropriate data about the serum of European bison Bison bonasus (Linnaeus, 1758). In blood researches of this species done up till now, the hematological parameters (Wołk, 1983) and serum proteins (Wołk & Jó-zefczak, 1984) were established. This paper reports the results of studies of 13 serum biochemical values and the activity of 8 serum enzymes in free-ranging bison.…”

Determination of hematological and biochemical values blood parameters for European bison (Bison bonasus)

“…Previously, studies in this field of veterinary diagnostics were conducted on European bison, but they could not determine the wide spectrum of blood parameters for healthy animals. Wołk et al [ 24 ] tested 46 European bison for hematological values; however, it was conducted only on European bison from Białowieska Forest, and for 12–82% of animals (depending on age group), invasive diseases were confirmed. However, the obtained results were quite similar to those obtained in our study.…”
