Efficacy Of Different Ionophorus Antibiotics Against Coccidiosis In Poultry
1992
Two hundred day old broiler chicks were purchased from a local hatchery and reared up to four weeks of age in hygienic conditions. After four weeks of age, chicks were divided randomly into four groups. Group A was kept as control, group B as infected non treated, group C as monensin treated and group D as salinomycin treated.
After four weeks of age, chicks of group B,. C and D were infected with mixed infection of avian Eimeria species, while group A was kept as control. Signs and symptoms of coccidiosis appeared after seven days of infection. After appearance of signs and symptoms the birds of group C and D were treated with monensin and salinomycin.
The effect of medication on feed consumption, weight gain, feed conversion ratio, mortality, oocyst count and dressing percentage were recorded weekly upto 7 week of age. There was significant difference (p<O.05) of feed intake between group B, C and D. Maximum feed intake was in group B, followed by group A, D and C respectively. Weight gain was maximum of group A followed by group B, D and group C respectively.
Feed conversion ratio (FCR) of control group A was better than all other groups while feed conversion ratio of group B (infected nontreated) was poor than all other groups.
Oocysts count was zero after six days of medication in group C (monensin treated) while it was zero after eight days of treatment in group D (salinomycin treated). Oocyst count was 120,000 oocysts/gm of faeces in group B (infected nontreated) after 49 days of age. While it remained zero through out the experiment in control group (group A). Mortality was maximum (33.50%) in group B (infected non treated) followed by in group D (10.22%) and group C (6.77%) respectively. While mortality remained zero in group A (control). Dressing percentage was better in group A (69.39%) followed by group D (65.30%), group C (63.07%) and group B (60.01%) respectively.
Observing the effects of monensin and salinomycin on feed intake, weight gain, feed conversion ratio, mortality, oocysts count and dressing percentage in experimentally infected (coccidiosis) chickens, it was concluded that monensin has comparatively better results than salinomycin.
