Stock Photo - ***MARCH 19, 1965, FILE PHOTO*** Ferrites against foreign bodies in cattle. Several tens of millions of CZK annually in our country are the economic losses caused by the necessary slaughter of cattle after the intrusion of foreign bodies, mainly metal objects, into the animal's intestines. Antonin Enenkl, a veterinary surgeon from the veterinary centre in Prostejov, has worked on solving this problem and has developed 'covered ferrite', which he has adapted to our production and material possibilities. The covered ferrite is a magnet in a plastic grid. Foreign bodies, usually nails, pieces of wire, etc., are magnetically attracted to the ferrite and fit into the grooves of the cover, thus preventing further injury to the wall of the cap. The capped ferrite can be swallowed by cattle from one and a half to two years of age. It remains in the animal's stomach for the duration of its life and binds any metal objects that the animal swallows with its food. Tests to date have been very successful. Experts believe that it is the only preventive scald that can significantly reduce losses due to foreign bodies in cattle.
