asked the Secretary of State for Scotland the number of local authorities in Scotland who have adopted the Ministry of Health model by-law 9b in regard to the slaughter of pigs up to 28th February?

I would refer the hon. and gallant Member to the reply which I gave to his question on this subject on 17th February. The position as I then explained it remains unchanged.

Has the hon. Gentleman any information as to the efficacy of the methods adopted under the model by-law 9b with regard to this. matter?

No, Sir. As I understand the matter, the conditions explained in the previous answer have not changed since that date.
