The most variable macronutrient concentration in the analyzed
samples was fat (0.96–8.26 mg%).
Using the Wilcoxon test, it was demonstrated that the process
responsible for the significant difference between the mean of the fat
and of the protein was pasteurization (pb0.001).
There were no significant differences in fat, protein and lactose
concentrations between the slow and quick thaw (Table 2). However,
the difference of the fat means between the gavage and continuous
