N =: number of lambs at each mating strategy; BW: birth weight; W3adj: adjusted weight at 3 months (weaning); W6adj: adjusted weight at 6 months; Diff1: difference of weights at birth to 3 months; Diff2: difference of weights at 3–6 months; ADWG1; average daily weight gain from birth to 3 months; ADWG2: average daily weight gain from 3 to 6 months; FTH: fat-tail height; FTW: fat-tail width. a,b: The means with the same letter in each column are not significantly different in Duncan’s multiple range test at 0.05 level.
