The high correlation between growth rate and adult body weight has been much more thoroughly documented for altricial birds than for precocial species. This paper gathers data from the literature for precocial Galliformes and also reports new growth data on six galliform species for analysis. The onset of homeothermic ability is investigated in Galliformes over a range of body size. The results confirm that (1) large species' chicks grow at a slower rate than those of smaller species, and (2) larger species' chicks can thermoregulate earlier than smaller species' chicks under cold stress situations. Published embryonic body weights are also analysed to determine when growth rate differences appear in the development of precocial species. No interspecific differences appeared in the relative growth rates of embryos, and therefore species body size does not appear to influence growth rate before hatching.
与早成雏物种相比，晚成雏鸟类生长速率与成年体重之间的高度相关性已有更为详尽的文献记载。本文收集了来自文献的早成鸡形目鸟类的数据，并报告了关于六种鸡形目物种的新生长数据以供分析。研究了一系列体型大小的鸡形目鸟类恒温能力的起始情况。结果证实：（1）大型物种的雏鸟生长速率比小型物种的雏鸟慢；（2）在寒冷应激情况下，大型物种的雏鸟比小型物种的雏鸟能更早地进行体温调节。对已发表的胚胎体重也进行了分析，以确定早成雏物种发育过程中生长速率差异何时出现。胚胎的相对生长速率未出现种间差异，因此物种体型大小在孵化前似乎不会影响生长速率。
