HC Deb 25 May 1988 vol 134 c218W
Mr. Tony Lloyd

To ask the Minister of Agriculture, Fisheries and Food how much milk is currently being produced in herds subject to BST testing.

Mr. Donald Thompson

The animal test certificates under which the trials are authorised permit the treatment of a maximum of 1,130 cows. However, the number of cows treated at any one time is likely to be less than this. Information on the volume of milk produced in herds involved in the trial is not available.
