Sustainable control of gastro-intestinal nematodes and lice infesting lambs

The parasiticidal drugs (fenbendazole + praziquantel @ 7 mg kg⁻¹ body weight once orally) and herbal (mercury - 100 mg, sulphur - 200 mg, ajmod - 300 mg, bayavidanga - 400 mg, nux-vomica - 400 mg, palas seed - 600 mg, pumpkin seed - 3 g, jira - 4 g, arecanut - 3 g and black til - 3g @ 500 mg kg⁻¹ body weight, twice daily for 7 days) anthelmintics and licicides (cypermethrin 15 EC @ 2ml litre⁻¹ water, sprayed once topically and neem oil - 50 ml + karanj oil 50 ml + camphor 10 g + sulphur 10 g topical, once daily for 5 days) applied simultaneously at an interval of about 2–3 months up to 300 days were found to keep the G.I. nematodes and lice infested growing lambs in almost free of both endo- and ectoparasites. The animals used in the study were maintained under semi-intensive farming conditions thereby indicating that the long term use of both endo and ectoparasiticidal control packages were effective in achieving sustainable control of parasitic infections in sheep.
