Genetic strain (North American Holstein, NAH, n = 8; New Zealand Holstein, NZH, n = 8) and days in milk interaction effect plots based on 1st component of ASCA (a), metabolites well modeled for ASCA interaction model (b) and bar plot of metabolites identified to have different temporal patterns between NAH and NZH cows according to ASCA (denoted by&) and/or top 10 MEBA’s ranking (denoted by //). Significant differences between means according to Tukey test are denoted by * whenever the ANOVA interaction effect P-value \(\le \) 0.10. The x-axis denote days in milk, the y-axis denote ion intensity peak height and error bars indicate standard deviation.
