The efficacy of semduramicin (AVIAX), a novel polyether ionophore, was profiled in a series of 57 battery tests conducted in the United States and the United Kingdom. The studies employed mixed and monospecific infections of Eimeria acervulina, Eimeria mivati/Eimeria mitis, Eimeria brunetti, Eimeria maxima, Eimeria necatrix, and Eimeria tenella derived from North American and European field isolates. Ten-day-old broiler cockerels in pens of 8 to 10 birds were continuously medicated in feed beginning 24 h before challenge in tests of 6 to 8 days' duration. At the use level of 25 ppm, semduramicin effectively controlled mortality, lesions, and weight gain depression that occurred in unmedicated, infected controls for all species. In comparison with 60 ppm salinomycin, semduramicin significantly (P < .05) improved weight gain against E. brunetti and E. tenella, lesion control against E. brunetti and E. maxima, and the control of coccidiosis mortality against E. tenella. Salinomycin was superior (P < .05) to all treatments in maintenance of weight gain and control of lesions for E. acervulina. Maduramicin at 5 ppm was inferior (P < .05) to semduramicin in control of E. acervulina and E. maxima lesions, but was superior (P < .05) to all treatments in maintenance of weight gain and control of lesions in E. tenella infections. The data indicate that semduramicin at 25 ppm is well tolerated in broilers and possesses broad spectrum anticoccidial activity.

Clinico-haematological and mineral studies were carried out in experimental chickens given maduramicin medicated feed at 5 and 10 ppm for 21 days. Maduramicin medication in both medicated groups caused growth retardation. Clinical signs namely watery diarrhoea, depression, dullness and ruffled feathers were noticed in chickens from second week of the medication at 10 ppm but this effect was seen from third week in the birds given maduramicin at 5 ppm. Maduramicin medication caused significant reduction in haemoglobin in both the medicated group from day 14 and total erythrocyte count and packed cell volume in 10 ppm group on day 21. There was an increase in MCV in 10 ppm group on day 21 indicating macrocytic anaemia and decrease in mean corpuscular haemoglobin concentration (MCHC) in both the medicated groups indicating hypochromic anaemia. The leucopenia due to lymphopenia was observed in 10 ppm group on day 21. Maduramicin medication caused significant increase in serum Zn in 10 ppm group and decrease in Cu concentration in both the medicated groups from day 14. It is concluded that maduramicin caused toxic effects from day 14 in both the medicated groups.
