Changes in the Concentrations of Serum Protein Fractions in Calves with Age and Nutrition

Figures & data

Figure 1. Distribution of the relative concentrations of albumin in the evaluated groups of calves. The plot shows the median (line within box), 25^th and 75^th percentiles (box), minimal and maximal values (whiskers).

Figure 2. Distribution of the relative concentrations of α₁- (a), α₂ - (b), β₁- (c), β₂ - (d) and γ-globulins (e) in the evaluated groups of calves. The plots show the median (line within box), 25 and 75 percentiles (box), minimal and maximal values (whiskers).

Figure 3. Distribution of the concentrations of total proteins in the evaluated groups of calves. The plot shows the median (line within box), 25^th and 75^th percentiles (box), minimal and maximal values (whiskers).
