    Abstract:
    The course of coccidiosis in lambs and the species of Eimeria involved were investigated in Saxony-Anhalt, Germany. A field study was conducted on three farms (conventional lamb-fattening farms) with 59 lambs. A total of 1092 faecal samples were taken during a period from about two to seven weeks after birth; the Eimeria species involved were determined in 415 of these samples and morphometrical characteristics of oocysts of 12 Eimeria spp. were recorded. Subclinical to moderate clinical coccidiosis was observed on all the farms and infections with Eimeria spp. were detected in all study lambs. 12 Eimeria species were identified on two of the farms (A and C): E. ahsata, E. bakuensis, E. crandallis, E. faurei, E. granulosa, E. intricata, E. marsica, E. ovinoidalis, E. pallida, E. parva, E. punctata and E. weybridgensis. The majority of these species were also detected on farm B, with the exception of E. granulosa, E. intricata and E. punctata. To our knowledge this is the first reported occurrence of E. punctata in Germany. Specimens with 3, 4 and 5 Eimeria spp. were the most common. E. ovinoidalis predominated in the faecal samples which underwent oocyst differentiation (> 90% positive samples on each farm). This species also accounted for the generally high oocyst counts observed. Since even subclinical coccidiosis may entail economic losses in lamb-rearing and considering the high prevalence of the pathogenic species E. ovinoidalis, appropriate monitoring of the disease in these farms is advisable.
