Table 6.9 'Height at withers (cm)': breed/location means for adults span 103.0 (Huanhu F: '103.0 +/- 0.3') to 137.5 cm (Sichuan Jiulong M: '137.5 +/- 8.8'); e.g., 'Tibet Alpine M 39 122.2 +/- 3.5 ... F 529 110.1 +/- 4.8'. Value is the midpoint of that span of breed means, not a population range. Wild yak (Bos mutus) bulls are far taller: 'a shoulder height for adult wild yak bulls of 175 - 203 cm' (Schaller 1998, quoted in the same FAO book, Ch. 1).
