Bull back scratcher that kills parasites.
Various shots of Mr Philip Young on his farm at Ringstead, Norfolk erecting a coil apparatus on side of barn. He pours anti parasite fluid down centre of coil. The young Hereford bulls then use the coil as a back scratcher, they get some sort of relief from this operation, and also kill parasites.
