This brush was developed in Scandinavia for keeping pigs happy in groups. It may help to relieve boredom and random biting and fighting, but it certainly helps combat itching and insects.
Mount securely at the right height, depending on size of pigs. They should be able to massage their head, back and flanks.
The brushes are replaceable. Very robust. Galvanised spring and frame.
Brushes are each 43cm x 10cm.
Also very useful for calves for the same reasons as pigs.
