Statistical analysis
Analysis of variance (ANOVA) and Duncan Multiple Range Test were carried out to compare the milk components.
Comparison of means of estimated concentration of different parameters in healthy and SCM milk, irrespective of the etiology, was done by t-test.
SCC was converted to Log10SCC. Pearson’s correlation coefficient among milk components showing substantial alternation in concentration between normal and SCM milk samples including Log10SCC was also calculated. Scattered plot graphs were plotted to describe the correlation between Zn and ALP in healthy as well as in SCM milk.
All statistical analysis was done with SPSS statistical software (Petrie and Watson, 2008).
