Antiparasitaeres Mittel

摘要

Parasiticidal compositions consisting of a biologically active dialkylvinylphosphate dispersed in starch, esp. acid-modified pyrodextrins, which are dispersed in wax. The compositions are active against insects and internal- and external parasites in mammals and birds, esp. poultry. They may be used for therapeutic- or prophylactic application as feedstuff additives. The compositions lower the toxicity of the parasiticides used while maintaining their activity; they may be mixed with feedstuffs without decomposition of the active component.
