Group A was treated in and group C in and each treated group was compared with a separate untreated group.
Some of the treated cows were identified as carriers of louse infestation subgroups A1 and C1while others were noncarriers subgroups A2 and C2.
Clinically, the treated cows, which were anemic at the time of treatment, recovered from anemia during the posttreatment period of 25 weeks for group A and 17 weeks for group C.
Remission of anemia also occurred in the two untreated groups, possibly because of natural summer decline in louse population. The treatment had no effect on the whole blood cholinesterase of the cows and the treated cows showed no signs of haematopinuss toxicity.
