数据包括出生时和大约6、12、18、24、30、36和48个月时的身体测量数据。身体测量包括体重、肩高、群高、胸围、体长、胸宽、胸深和前炮骨周长。一般来说，五月出生的马驹往往比其他月份出生的马驹要大。在6个月、12个月和24个月时，差异有统计学意义。5月份出生的马驹在前半年的生长速度比其他月份出生的马驹快（p≤0.01 ~ p≤0.001）。在6 ~ 12月龄期间，7 ~ 8月出生的马驹生长发育较早出生的马驹慢（p≤0.05 ~ p≤0.001）。它们在第一年的生长速度也比更早出生的马驹慢。马驹的性别主要影响炮骨周长。总的来说，男性往往比女性更高、更长、更宽，但更轻、更瘦。大型母马的后代体型更大，而且……
Abstract The data consisted of body measurements recorded at birth and then approximately at ages 6, 12, 18, 24, 30, 36 and 48 months for 488 Finnhorse foals. Body measurements included body weight, height at withers, height at croup, heart girth, body length, chest width, chest depth, and circumference of front cannon bone. In general, foals born in May tended to be larger than foals born in any other month. Differences were statistically significant at ages 6, 12 and 24 months. In the first half year of life foals born in May grew faster (from p≤0.01 to p≤0.001) than foals born in any other month. During the period from 6 to 12 months foals born from July to August grew slower than foals born earlier (from p≤0.05 to p≤0.001). They also grew slower during their first year of life than foals born earlier. Sex of a foal primarily influenced cannon bone circumference. In general, males tended to be taller, longer and wider but lighter and leaner than females. Offspring of large mares were larger in size and...
