Large White, local Samoan and Large White X local Samoan crossbred pigs were fattened under 3 different systems of management. Under the first, simulating village conditions, pigs were fenced in a grass paddock and fed copra and scraps. The crossbreds grew significantly faster than Large White and local Samoan pigs. In the second system where a 30% crude protein supplement was fed in addition to feedstuffs from village resources there were no significant differences in production characteristics between the various types of pigs. The growth rate of all groups of pigs still lagged behind the growth rate of Large White and crossbred pigs in the third system fed a complete balanced diet. Under commercial management local Samoan pigs grew more slowly and had a higher feed conversion than Large White and crossbred pigs.
大白猪、当地萨摩亚猪以及大白猪与当地萨摩亚猪的杂交猪在3种不同的管理系统下育肥。在第一种模拟乡村条件的系统中，猪被圈养在草地围场里，喂食椰干和残羹剩饭。杂交猪的生长速度明显快于大白猪和当地萨摩亚猪。在第二种系统中，除了乡村资源提供的饲料外，还喂食了30%的粗蛋白补充剂，不同类型猪的生产特性没有显著差异。在第三种喂食完全平衡日粮的系统中，所有猪群的生长速度仍落后于大白猪和杂交猪。在商业化管理下，当地萨摩亚猪的生长速度比大白猪和杂交猪慢，饲料转化率更高。
