Sir,—Having read with interest the letter by R. H. Hiscock in the Veterinar'y Record (Vet. Rec. (1962), 74: 1140), I would like to record a similar experience, using the same product on some “tail end” Jersey calves, five to six months of age, which weighed between 100 lb and 160 lb each. They were very poor calves indeed.
