HC Deb 17 November 1947 vol 444 c803
50. Mr. Skeffington-Lodge

asked the Minister of Agriculture to what extent his Department has encouraged the use of D.D.T. or similar preparations for spraying livestock both with the object of pre serving their hides and their health, as well as saving them from the unnecessary cruelty inflicted on them by flies and other insects in hot weather.

Mr. T. Williams

I am advised that D.D.T. and similar preparations when used as sprays on livestock have a very limited value as protectives against flies and other insects, although as dips for sheep they are proving very successful. The Ministry's veterinary officers generally recommend the use of these products for suitable purposes.
