Effect of subclinical coccidiosis in kids on subsequent trichostrongylid infection after weaning.
Seven-week-old female kids of the Murciana-Granadina breed naturally infected with coccidia were superinfected with a multispecific Eimeria inoculum (300,000 oocysts) or treated to control the coccidial infection with Amprolium (50 mg kg-1 liveweight day-1; 4 days every 14 days); 80 days later both animal groups received 2500 third-stage larvae of a sheep-derived mixture of Trichostrongylus colubriformis (50%), Teladorsagia circumcincta (40%) and Haemonchus contortus (10%). Kids experimentally superinfected with Eimeria showed reduced food intake at the early patency period, higher numbers of oocysts passed at weaning time and lower liveweight gain than the Amprolium-medicated kids. In the Eimeria superinfected kids the trichostrongyle infection caused a tendency to result in chronic coccidial infections. Further, these animals had higher numbers of nematode eggs in their faeces, lower dressed weights on slaughter and inferior meat quality.
