The aim of the study was to compare the contents of individual protein fractions determined by electrophoresis in the blood serum of 32 periparturient goats supplemented with various forms of zinc (Zn). Goats were divided into four groups: Group A was a control (without Zn supplementation). The remaining three groups (B, C, D) were supplemented with Zn in various forms. Group B was supplemented with zinc oxide, Group C with zinc lactate, and Group D with zinc chelate. Individual protein fractions (albumins, α1, α2, β1, β2 a γ-globulins) were identified by electrophoretic analysis. All supplemented groups showed the trend of a positive influence of Zn on γG fractions in the serum protein of the goats; this tendency was significant only in Group C. Moreover, Group C had significantly the highest total protein values and albumins. The results indicated that a feed enriched with various forms of Zn had a significant influence on the quantity of individual protein fractions of blood serum. Our results provide new knowledge on the values of individual protein fractions of serum goats and should be taken into consideration when interpreting the serum protein profile with regard to periparturient goats. Furthermore, we showed the possible positive or negative effects on the values of individual fraction on serum proteins with organic and inorganic zinc form supplemented rich in diet.
