§ Mr. A. WILLIAMSasked the Minister of Health the number of pedigree dairy herds which are supplying certificated Grade A tuberculin tested milk at the present time; whether all animals in these herds have been tested for tuberculosis: and, if so, at what age calves have to be tested?

Mr. CHAMBERLAINThere are approximately 200 herds producing certified or Grade A (tuberculin tested) milk, but I have no information as to how many of these are pedigree herds. The cows in milk in these herds and all the animais which are in contact with them are required by the Milk (Special Designations) Order to be submitted to the tuberculin test. Calves are not usually kept in contact with these cows, and consequently there is no necessity for young stock to be tested until they are introduced for milking purposes. If in any case calves are kept in contact with the cows they must be tested at the tine of the general tests of the herd.
