Last week Mr Davies said advice from veterinary experts and weather forecasts from the Met Office made it clear that the derogation allowing on-farm burial was still necessary.
The relaxation in the use of hauliers to collect dead animals applies until midnight on 7 May, one week after the end of the derogation permitting burial in certain circumstances.
He said the Aggregates Levy was a stealth tax introduced by Gordon Brown, but that the derogation scheme for Northern Ireland had introduced effective environmental controls to the quarry industry.
And underlying this confusion is a further derogation - that of an ideal both men shared, which was that the municipalities of the future should utilise increasing land-values to improve the collective lot.
However, agencies are asking supply teachers to sign a contract - known as a Swedish Derogation - to waive this right in exchange for continuous employment or a minimum payment if work is not available.
