The Effects of Coriandrum sativum L. and Cucurbita pepo L. against Gastrointestinal Parasites in Swine: An In Vivo Study.

Abstract

Parasitic diseases are responsible for substantial losses in reproduction and productivity in swine, creating a major impairment to efficient and profitable livestock management. The use of phytotherapeutic remedies has notably increased over the past decade due to their bioavailability, decreased toxicity, non-polluting nature, and to some extent due to their antiparasitic effect. The aim of this study was to evaluate the antiparasitic potential of Cucurbita pepo L. and Coriandrum sativum L. against protozoa and nematodes found in swine. The samples were collected from weaners, fatteners, and sows and examined via flotation (Willis and McMaster), active sedimentation, Ziehl-Neelsen staining as modified by Henricksen, a modified Blagg method, and eggs/oocyst culture. The parasite species detected were Ascaris suum, Trichuris suis, Oesophagostomum spp., Balantioides coli (syn. Balantidium coli), Eimeria spp., and Cryptosporidium spp., depending on age category. A dose of 500 mg/kg bw/day of C. pepo and 170 mg/kg bw/day of C. sativum powders, administered for ten consecutive days, demonstrated a pronounced anthelmintic (pumpkin) and antiprotozoal (coriander) effect against the aforementioned parasites. Future studies are required to ascertain the optimal dose that maximizes their antiparasitic effectiveness. The current study represents the first Romanian report on the in vivo antiparasitic activity of these two plants tested on digestive parasites in swine.
