Effects of Artemisia annua and Foeniculum vulgare on chickens highly infected with Eimeria tenella (Phylum Apicomplexa)
BACKGROUND Intensive poultry production systems depend on chemoprophylaxis with anticoccidial drugs to combat infection. A floor-pen study was conducted to evaluate the anticoccidial effect of Artemisia annua and Foeniculum vulgare on Eimeria tenella infection. Five experimental groups were established: negative control (untreated, unchallenged); positive control (untreated, challenged); a grou...

15 صفحه اولEvaluation of Kadaknath Chicken for Coccidial Resistance by Oocyst Count, Lesion Scoring and Oocyst Index in Eimeria Tenella Infection
The aim of present investigation was to study the virulence of coccidiosis in Kadaknath birds, experimentally infected with E. tenella by OPG count, oocyst index and caecal lesions scoring. Sixty one-day old unsexed Kadaknath birds were randomly divided into a control, T1 and T2 groups comprising twenty chicks under each group. At d 21 of age, birds of T1 and T2 groups were individually inocula...
متن کاملBacterial Population Changes in the Ceca of Young Chickens Infected with Eimeria tenella.
Eimeria tenella, a protozoan parasite belonging to the class Sporozoa, is the etiological agent of cecal coccidiosis of chickens. This organism goes through a typical sporozoan life cycle and, with the exception ofsporulation of the oocyst, all stages occur within the host's intestinal tract. Invasion of the intestinal epithelium by sporozoites and merozoites results in considerable tissue dest...
