Coccidiosis is a disease caused by protozoan parasites, mainly from the Eimeria genus, generally located in the intestine. With the risk of becoming rapidly resistant to certain molecules, these parasites are transmitted by a highly infectious process (essentially via oral-fecal route). Present in all farming systems, coccidiosis is particularly harmful for young monogastric animals (poultry coccidiosis, young ruminants coccidiosis, piglets and rabbits coccidiosis) for which health consequences can be significant: loss of appetite, reduction of feed intake, enteritis, hemorrhagic diarrhea…
In the poultry industry, 98% of the farms use an anticoccidial solution, for an overall cost estimated at 800 million dollars in preventive treatments (Graff et al.; 1999; Williams, 1998). Coccidiosis represents a loss of 3 billion $/year for the poultry industry (thepoultrysite.com, 2013).
The disease control is principally made through the use of synthetic coccidiostats of which a long-term and large scale use causes antimicrobial resistance (Long, 1982; Stephan et al., 1997; Yadav and Gupta, 2001; Arabkhazaeli et al. 2013). Plant-based feed additives represent interesting alternatives for all species.
