^aWeaning weight = weight at end of milk feeding period

^bTurnout weight = weight at end of concentrate feeding and before turn out to grass

^cEnd weight = weight after 3 months at grass

^dADG = Average daily gain over a 172-day period starting on d 0 of the experiment

^eFecal score ranged from 1 to 4; 1 = firm, 2 = semi-solid, 3 = liquid, 4 = very liquid

^fInteractions are described in the text when significant

ns not significant
