Analysis of variance adopts the method of the F test. The F value in the result represents a specific value obtained by using the formula of the F test. According to this value, the corresponding p value can be obtained by looking up tables or other methods, that is, Sig. DHI is dairy herd improvement; TDMY is test-day milk yield; FC is fat content; PC is protein content; SCS is somatic cell score; *: p < 0.05; **: p < 0.01; a,b differences in the same column are significant at p < 0.05.
