The values are expressed as least squares means (Lsmeans) and s.e.

G = gender, L = location, T = time, I = interaction, NS = not significant (P > 0.05). * = P < 0.05, ** = P < 0.01, *** = P < 0.001.

^{a, b, c}Within rows, Lsmeans differ from pre-weaning baseline by P < 0.05, P < 0.01 and P < 0.001, respectively.

¹Gender × Location × Time interaction, near male 57.9 vs away male 68.1 at time 7

²Gender × Time interaction, 857.9 vs 773.8, 1043.4 vs 861.7, 1037.9 vs 868.5, 1013.9 vs 751.7, 787.8 vs 691.2, 491.6 vs 499.7 for male and female calves at time 0, 1, 2, 3, 7 and 11, respectively.
