HC Deb 04 December 1967 vol 755 c240W
Sir J. Gilmour

asked the Secretary of State for Scotland what is his estimate of the comparative values in starch equivalent and digestible crude protein which would accrue to the grower in Scotland from a crop of field beans yielding one ton to the acre as compared with a crop of sugar beet yielding tops at 12 tons to the acre plus the value of beet pulp available for purchase on the Cupar factories' average yield.

Mr. Ross

On the basis of standard methods of calculating feeding values, the starch equivalent value for sugar beet (tops and pulp) and field beans (including straw) would be in the ratio of about 2: 1; for digestible crude protein the values would be about equal.
