An investigation was carried out on coccidial infection in domestic goats (Capra hircus) managed under three different rearing systems (intensive, semi- intensive, and extensive) at Kalubyia governorate, Egypt. Eimeria oocysts were found in 93 (66%) of the 141 faecal samples examined. Six species of Eimeria were morphologically identified; E. hirci (90.32%), E. arloingi (83.87%), E. alijevi (75.27%), E. christenseni (63.44%), E. caprina (29.03%), and E. ninakohlyakimovae (24.73%). Up to six Eimeria species were recorded form individual specimen. The infection rates and the mean number of oocyst outputs (OPG) decreased with increasing age of goats; 80% and 31758.08 for kids; 72.92% and 19543 for young; and 30.30% and 1769.92 for adult goats, respectively. Mortalities, 20.83%, were observed in kids managed under the intensive system. Toltrazuril (20 mg/kg body weight, orally, Baycox, Bayer) was highly effective as anticoccidial drug (94.33% reduction of OPG). On the other hand, propolis (1ml of 3% aqueous solution /liter of drinking water for 7 days) moderately reduced OPG (54.66%) and stopped diarrhoeas. Therefore, both treatments significantly reduced the environmental contamination with oocysts.
