Coffee bean seed (Cassia obtusifolia) was ground and mixed in the feed at levels of 2,5, and 10% and fed to White Leghorn hens. Feed consumption and egg production were reduced by all three although more so at 5 and 10%. Feed consumption and egg production had not returned to control levels four weeks after the adulterated feed was suspended, though the response was more pronounced in the younger birds. The semitendinosus and pectoralis superficialis muscles were pale and edematous at postmortem examination of the birds, being most pronounced at the 5 and 10% levels.
咖啡豆种子（决明子）被研磨后以2%、5%和10%的比例混入饲料中，喂食白来航鸡。这三种添加水平均降低了采食量和产蛋量，不过5%和10%水平时降低得更多。在停用掺假饲料四周后，采食量和产蛋量仍未恢复到对照水平，尽管幼龄鸡的反应更为明显。在对这些鸡进行尸检时，半腱肌和胸浅肌苍白且水肿，在5%和10%水平时最为明显。
