§ 49. Brigadier-General Clifton Brownasked the Lord President of the Council whether enough owners of milk herds have been secured to carry out the Agricultural Research Council's field experiments to test their B.C.G. vaccine for the control of bovine tuberculosis; and whether these experiments, as far as they have gone, are proving successful?
§ Captain McEwen (Lord of the Treasury)I have been asked to reply. The Agricultural Research Council, with the collaboration of the Ministry of Agriculture and Fisheries, have been fortunate in finding sufficient herds to start the field experiments with B.C.G. vaccine, and further herds may be included in the future. The test is one which must last over 5–6 years, of which the present is the first. It is clearly much too early to reach any conclusions.
§ Mr. LeachWhat is bovine tuberculosis, and why are no deaths reported from it in the Registrar-General's returns or the Ministry of Health figures?
§ Captain McEwenI could not answer that question without notice.
