Terrill et al 2012 highlight the research trends in ovine medicine by stating that anthelmintic resistance is reaching epidemic proportions in small ruminants in the U.S. and that non-chemical control alternatives are critically needed.  They describe the generally warm, moist environmental conditions in the southern United States (U.S.) as ideal for survival and growth of the egg and larval stages of Haemonchus contortus and other gastrointestinal nematodes (GIN) of sheep and goats. Critically, infection with GIN is the greatest threat to economic small ruminant production in this region. They also highlight the emerging markets for grass-fed and organic livestock36.

 

A global focus on botanical medicine- plant extracts for the management of gastrointestinal parasites is exemplified by a 2014 review by Mbaya etal, show that extracts of various species of medicinal plants have shown significant in-vivo and in-vitro pharmacological activities against ecto, endo and haemoparasites. They point out that the scientific evaluations of the use of the plants as antiparasitic agents were based on the claims of ethnoveterinary medicine. The pharmacological activities of these plants were associated with the presence of various bioactive compounds such as alkaloids, flavonoids, saponins, glycosides, allicinine, harmala, harmaline, harman, tetrahydroharman, ursolic acid, terapines, tannins, phenolic compounds, embelin and brucine. In the in-vivo studies, plant extracts were tested using animal models such as mice, sheep, goats, cattle and dogs37.

 

Botanical medicines are also finding potential in reducing lamb mortality and improving ewe performance (Smeti etal 2015)38; improving ewe milk production (Giannenas etal 2011)39 possibly through activity on the rumen microbiota in work conducted with the Department of Animal Sciences, The Ohio State University (Cobellis etal 2016)40; providing alternatives to  blow fly control  (Callander etal 2012)41 and lice treatment (James etal 2012)42 and ovine dermatophytosis (Mugnaini  etal 2013)43.
