要 約
浮腫病発生農場において,離乳子豚舎の舎内温度と死亡事故との関係について調査した.浮腫病罹患子豚の死亡頭数は,舎内温度が32℃以上を記録した日から7日目まで増加し,その間に死亡した頭数は,有意に増加していた(P<0.05).このことから,暑熱が,本農場における浮腫病の発症に関与している可能性が示唆された.
―キーワード:浮腫病,死亡,舎内温度.

SUMMARY
Our investigation of the association between nursery temperature and mortality
on a farm where edema disease was occurring showed that, when the temperature rose to 32℃ or higher,
mortality of the piglets due to edema disease increased within 7 days after a given date. The increase
in numbers of dead piglets during this period was significant (P<0.05). These results suggest
that, on this farm, high nursery temperatures contributed to the outbreak of edema disease.
―Key words : edema disease, mortality, nursery temperature.
