Coccidiosis is caused by the apicomplexan protozoan Eimeria and is recognized as the most Important parasitic disease of poultry (Conway & Mckenzie, 2007). Coccidiosis seriously affects the growth and feed utilization of infected animals resulting in loss of productivity (McDougald, 2003; Safari et al., 2004). Conventional disease control strategies rely heavily on chemoprophylaxis (anticoccidial feed additives). With increasing regulations and bans on the use of anticoccidial drugs coupled with the associated costs of developmg new drugs urges, there is a pressing need to develop novel approaches and alternative control strategies such as vaccination. The cutTent bulletin summarizes the zootechnical results of the use of a coccidiosis vaccine "Paracox 5" under Moroccan field conditions in 5 farms; including 3 free-range chicken farms marketed under the brand name "EL HOR" and supervised by Dr Oussama Chorfi. In conclusion, "Paracox 5" vaccine improved the zootechnical performance of both broiler and free-range chickens compared to control batches, right from the first time it was used in the farms.
