Fetal:maternal weight ratio (%) of lambs at term split according to (A) singleton/twin, (B) male/female or (C) high/medium/low body condition score ewes. Values are mean±s.e.m. for individual data points of singleton (n = 95) and twin lambs (n = 50) and for low (n = 29), medium (n = 122) or high (n = 15) body condition score of ewes at mating. See Materials and Methods for details. Statistical differences are, *P<0.001 singleton versus twin; male versus female. C, differing superscripts indicate statistical difference at P<0.001.
