    Four normal calves, Nos. 1 to 4, were administered orally with 300, 100, 50, and 25kg, respectively, of the insecticidal carbamate, 2-sec-butylphenyl-N-methylcarbamate (BPMC).
    (1) Salivation, miosis, difficulty in standing up, tachypnea, tachycardia, slight elevation of body temperature, and diarrhea were observed in 3 calves, Nos.1 to 3. They occurred within 7 to 10 minutes after administration. No.1 died 25 minutes later. The other calves recovered.(2) Depression of choline esterase activity of plasma and red blood cells was marked in all the calves, except No.4. A slight increase in erythrocyte count was seen in Nos. 1 and 2 mild leukocytosis and neutrophilia in Nos. 2 and 3 and a slight increase in serum total protein in all the calves.(3) It was considered that BPMC might be absorbed rapidly from the alimentary tract and discharged early.

    In 28 calves experimentall yinfected with Dictyocaulus viviparus alone, first-stage larvae disappeared from feces 83.2 ± 33.3 days after infection. In 9 calves, they did not disappear from feces within 100 days after infection. They disappeared on the 186th day at the latest.
    In an experiment one calf moderately infected with D. viviparus was grazed together with 4 susceptible calves. In another experiment one mildly infected calf and 4 susceptible calves were grazed together. In the former and latter experiments, 3 and 2 calves, respectively, became infected during the grazing period. There was no difference in the severity of infection among the calves between the two experiments. The infected calves showed lower body weight gain than the uninfected.

    A disease with diarrhea as a main symptom broke out among adult chickens on a poultry farm in Niigata Prefecture. Affected birds presented anemia and a decrease in egg yields. The morbidity rate varied from 30 to 80% depending upon the amount of a particular lot of a particular ration. Pathological examination revealed hemorrhagic, necrotic enteritis or diphtheric enteritis. Clostridium perfringens type A was isolated from the residual feed, as well as the affected chickens. Enterotoxin was demonstrated in the intestinal contents. When inoculated with spores of the isolated organism, chickens manifested essentially the same symptoms as the affected ones.
