HC Deb 21 February 1968 vol 759 c128W
Mr. Gibson-Watt

asked the Minister of Agriculture, Fisheries and Food what estimate he has made of the number of bulls used to run out with herds in England and Wales, respectively.

Mr. John Mackie

It would be difficult to estimate; but the running of bulls with the herd is an essential feature of all single suckler herds.
