Multiple comparisons of the intercept and slope of linear regression equations between overall dynamic body acceleration (ODBA) and heart rate in the species and breeds tested.

The effects of the groups of species and breeds on the intercept and slope were significant (P<0.01). The linear relationship has the form HR = b0+ b1∙ODBA, where HR is heart rate (beats/min), ODBA is overall dynamic body acceleration (g), and b0 and b1 are the intercept and slope of the regression equation, respectively. *Values are least square means with standard errors. a,b,c Values within a column with different superscripts differ significantly (P<0.05).
