Least squares means and standard error of the combined Treatment × Month effect for milk coagulation traits (RCT: Rennet coagulation time, k20: Curd-firming rate as time to a curd firmness of 20 mm, a30 and a45, respectively: Curd firmness after 30 and 45 min from rennet addition) of Brown Swiss cows kept on the permanent farm (■ and continuous line) or moved to highland summer pasture from July to September (○ and dotted lines). Equations describe the trends of month within permanent farm (R2 is shown). Differences between cows moved to highland summer pasture and those kept on the permanent farm in a given month were never significant (p > 0.05).
