Data analysed by hand for earlier papers in this series have now been analysed by a least-squares method. Three production indices--liveweight of young weaned per breeding female, per kg of breeding female and per kg metabolic weight of female--are calculated. For different variables parity and type of birth had significant effects on one or more indices for goats while sex, parity and flock had significant effects for sheep. Goats in general had greater indices than sheep and the transhumant system was better than the sedentary but the effects were not significant for these variables.
本系列早期论文中通过手工分析的数据现在已采用最小二乘法进行分析。计算了三个生产指数——每只繁殖母羊的断奶幼崽活重、每千克繁殖母羊的断奶幼崽活重以及每千克母羊代谢体重的断奶幼崽活重。对于不同变量，胎次和出生类型对山羊的一个或多个指数有显著影响，而性别、胎次和羊群对绵羊有显著影响。总体而言，山羊的指数高于绵羊，游牧系统优于定居系统，但这些变量的影响不显著。
