§ Mr. Snowasked the Minister of Agriculture the number of poultry blood-tested under his Department's arrangements for the latest convenient period in 1951 and for the same period in 1950, in the county of Staffordshire.
Mr. T. WilliamsThe number of birds tested for bacillary white diarrhoea in Staffordshire by my Department's officers between 1st May and 30th June, 1951, was 26,200, as compared with 21,560 tested in the same period last year.
§ Mr. Snowasked the Minister of Agriculture what check is employed by his poultry advisory officer in the county of Staffordshire to ascertain the true number of poultry yet to be blood-tested this year.
Mr. T. WilliamsA list of the flocks to be tested for bacillary white diarrhoea is compiled at the beginning of the season by the county poultry advisory officer. The approximate number of birds in each146W flock is known from previous tests or, if there has been no previous test, from the report of the advisory officer's inspection. As the veterinary officers are supplied with these particulars they are able to compute, whenever it is necessary to do so, how many birds remain to be tested.
