ザンビアの1農場では, ナミビアから6週齢のダチョウを51羽輸入した. これらのダチョウは食欲不振, 下痢などの症状を呈し, 導入後1週間に19羽が死亡した. 死亡鳥4羽を剖検したところ, 腺胃および筋胃内にトウモロコシを混じたアルファルファ乾草が塊となって充満し, 極度の通過障害を起こしていた. 死亡鳥と発症鳥の細菌検査, 寄生虫検査は陰性であった. 給与飼料を改善し, 発症鳥に粘漿剤を投与したところ回復した. 以上の成績から, 本症例はダチョウにみられた食滞(stomach impaction)と診断された.
Fifty-one ostriches (Struthio camelus), 6 weeks old, were imported from Namibia and introduced onto a farm in Zambia. Soon after introduction, most of the birds manifested clinical symptoms such as anorexia and diarrhea and 19 birds died within 1 week. The proventriculus and gizzard in the 4 dead birds were full of solid masses of lucerne hay mixed with maize and consequently the gizzard was extremely impacted by them. Neither pathogenic bacteria nor parasites were detected from the autopsied birds and 8 fecal samples. After diagnosis, the ostrich feed was improved and a demulcent was given immediately; then all ostriches that remained on the farm recovered. In conclusion, these data confirmed that the present case was stomach impaction in ostriches.
