Each index is reported as mean ± standard deviation of the calculated value for each animal within the experimental group. The statistical comparison was considered only between the experimental groups of the same breed through Kruskal-Wallis test

HFC, Holstein-Friesian cows; HFH, Holstein-Friesian heifers; SIC, Simmental cows; SIH, Simmental heifers
