Managing the risk of occidiosis

Nor-Feed Natural Solutions against poultry coccidiosis

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…

Coccidiosis has an extremely heavy economical impact

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).

Coccidiosis prevention solutions in farms

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.
