Some canny upcycling has simplified calf feeding for Dan Roberts of Pwll Farm, Treuddyn.

His 5m-long portable trough is made from five spare AdBlue barrels, which were sliced lengthways and bolted to a box-section frame assembled from the remnants of a shed door.

He parted with £80 in exchange for an old trailer axle and, at the front, fitted a detachable drawbar. Drop legs keep the trough level when it’s in use.

He has since knocked together a slimmer version featuring five half-drums in a single row.
