title: [Studies of the high toxicity of zinc-metallibur].
abstract: The high toxicity of Zine-Metallibur was tested in gilts aged eight months and weighing between 78 and 96 kg. Zinc-Metallibur, either 1 g/kg live weight or a quantity 1,000 times that used for synchronisation, was admixed to feed rations and introduced directly into the stomach through and intra-oesophageal tube. Fodder with the entire dose admixed is rejected by the pig. Direct intragastric administration of the same amount, however, is possible and does not cause death.
