Results: In the published studies, administration of D. flagrans spores resulted in statistically-significant improvements in a wide variety of parasitological parameters:-

Cattle: The most common measure studied was the number of infective parasite larvae on pasture, where reductions of up to 90% were obtained (Hertzberg et al., 2007). In addition, reduced infection levels in the grazing animals was demonstrated by means of (1) the number of parasite eggs per gram (epg) in their faeces/manure, where reductions of approximately 60% were obtained (Assis et al., 2012, 2013, Dias et al., 2007) and (2) total worm count, with up to 87% reduction achieved (Wolstrup et al., 1994). In a number of trials parasitosis occurred in the control group but was prevented in the treatment group (Larsen et al., 1995, Nansen et al., 1995, Sarkunas et al., 2000 and Fernandez et al., 1999c). Improved live weight gain of up to 25% was observed during the grazing period, resulting from reduced loss of productivity due to parasitism (Nansen et al., 1995). In addition, treatment with D. flagrans spores was shown to reduce larval emergence in coproculture (which is the culture of faeces/manure for the detection of larval types and numbers) by up to 98% (Fernandez et al., 1999a).
