The aim of this study was to evaluate total serum protein concentration measured using biuret reaction and the protein fractions determined using acetate cellulose electrophoresis in Ragusana donkeys (Equus asinus). Blood samples were collected from 68 clinically healthy female donkeys by jugular venipuncture. The serum levels of total proteins were determined using biuret method, and the separation of proteins was performed using acetate cellulose electrophoresis. Coefficients of variation were also calculated for within-assay precision, and were found to be less than 5% for α- and β1-globulins and 8% or less for albumin, β2-, and γ-globulins. A total of five protein fractions were separated and quantified: albumin, α-, β1-, β2-, and γ-globulins. Data obtained from young and adult subjects were compared using the Mann–Whitney U test. Reference intervals (2.5%-97.5% quantiles) were determined for total proteins (50.0-84.0 g/L), albumin (16.2-36.6 g/L), α-globulins (4.85-19.5 g/L), β1-globulins (2.25-10.35 g/L), β2-globulins (3.30-14.85 g/L), γ-globulins (10.0-30.5 g/L), and albumin/globulin ratio (0.41-1.13). In relation to age, statistically significant differences were found in total protein concentration and γ-globulins. The results obtained in the present study contributed to establish reference intervals of serum protein fractions obtained using acetate cellulose electrophoresis in female Ragusana donkeys to be used by practitioners for health control.
