Addition of a combination of onion (Allium cepa) and coconut (Cocos nucifera) to food of sheep stops gastrointestinal helminthic infections

Sheep with gastrointestinal nematodes and cestodes were fed on three farms with a combination of specially prepared extracts of onion (Allium cepa) and coconut (Cocos nucifera) for 8 days containing each 60 g coconut and onion extract, combined with milk powder and/or polyethylene glycol (PEG) propylencarbonate (PC). In all cases, the worm stages disappeared from the feces and were also not found 9 and 20 days after the end of the feeding with this plant combination. Since all treated animals increased their body weight considerably (when compared to untreated animals), worm reduction was apparently as effective as it was shown in previous laboratory trials with rats and mice (Klimpel et al., Parasitol Res, in press, 2010; Abdel-Ghaffar et al., Parasitol Res, in press, 2010; in this volume).
