Leukocyte intracellular killing test and selected proteins in Polish mixed-breed rabbits

The study involved an analysis aimed at developing standards regarding leukocytes’ IKT, number of serum IgG and total volume of serum immunoglobulin, as well as total protein volume in the blood serum of rabbits, considering the impact of their sex and season of the year on the parameters analyzed. The study was performed on a representative group of Polish mixed-breed rabbits and Polish mixed-breed rabbits with the addition of blood of meat-breeds at the age of 6-8 months. The obtained results of the study in typical Polish mixed-breed rabbits and Polish mixed-breed rabbits with the addition of blood of meat-breeds are similar, as in typical Polish mixed-breed rabbits IKT values amounted to 0.65-0.70; serum IgG ranged from 14.1 to 17.2; total Ig in ZST units amounted to 20.16–31.36, and total protein in serum: 54.14– 62.86. In turn, in Polish mixed-breed rabbits with the addition of blood of meat-breeds, IKT values amounted to 0.56–0.65; IgG: 13.1–16.9; total Ig in ZST units: 21.36–31.14, and total protein in serum 48.49–59.16. In the case of both typical Polish mixed-breed rabbits and Polish mixed-breed rabbits with the addition of blood of meat-breeds, little impact of sex was observed on the values of the parameters analyzed, opposite to the season of the year. The latter parameter, in typical Polish mixed-breed rabbits, affected the values of serum IgG values, while to a slightly smaller extent total serum Ig in ZST units, whereas in the case of Polish mixed-breed rabbits with addition of blood of meat-breeds, the season equally strongly affected both serum IgG and total serum Ig in ZST units.
