The West African dwarf (WAD) is the prevailing breed in the South Western part of Nigeria, whereas Permer (P) is a cross of Persian and Merino sheep. Since the mortality rate is unacceptably high in Permer-even under favourable conditions-several plasma variables were determined in 5 WAD and WAD X P rams twice on Mondays over 5 weeks with a view to health prophylactic measures. Differences between the breeds were found that did not, however, in any case agree with the values found by other authors and that suggested a connection with certain diseases. This should be investigated in investigations to come.
西非矮种羊（WAD）是尼日利亚西南部的主要品种，而佩尔梅羊（P）是波斯羊和美利奴羊的杂交品种。由于即使在有利条件下，佩尔梅羊的死亡率也高得令人无法接受，因此在5周内的每周一，对5只西非矮种羊和西非矮种羊与佩尔梅羊的杂交公羊进行了两次多项血浆变量测定，以采取健康预防措施。发现了品种之间的差异，然而，这些差异在任何情况下都与其他作者发现的值不一致，并且表明与某些疾病有关。这一点应在未来的研究中进行调查。
