On September 16, 1959, six Shetland ponies were admitted to the I.S.U. Veterinary Clinic. These ponies were from a band of thirty animals that had been sold and shipped to an eastern state in the spring. When returned here the animals all were in poor condition, and had a history of having shipping fever all summer. Examination showed all animals to be infected with strongyles. A standard therapeutic dose of phenothiazine was administered to the animals. No hemoglobin determination was made prior to treatment
