Publisher: 1994Dissertation note: Two hundred and fifty, day old quail chicks were pruchased from a local hatchery and reared up to three weeks of age under hygienic conditions. After three weeks of age, quails were divided randomly into five groups. Group A was kept as control, group B as infected non treated, group C as monensin treated, group D as salinomycin treated and group E as suiphaquinoxalim treated.
After three weeks of age, groups B, C, D, and E were infected orally with mixed infection of avian Eimeria species, while group A was kept as control. Signs and symptoms of coccidiosis apperared after six days of infection. After apperarance of signs and symptoms the birds of group C and D were treated with monensin and salinomycin and group E treated with sulphaquinoxaline.
The effect of medication on feed consumption, weight gain, feed conversion ratio, mortality, oocyst count and dressing percentage were recorded weekly upto 6 weeks of age. There was significant difference (P<O.05) of feed intake between group B, C, D and E. Maximum feed intake was in group A, followed by group E, C, D, and B, respectively. Weight gain was maximum of group A followed by group E, C, D, and B respectively.
The 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 on six days post of medication in group C, (monensin treated) while it was zero after eight days of treatment in group D (salinomycin treated) and oocyst count was zero after four days of medication in group E (suiphaquinoxaline treated). Oocyst count was 32.000 oocystlgm faeces in group B (infected nontreated) after 42 days of age. While it remained zero through out the experiment in control group (group A). Mortality was maximum (10%) in group B (infected non trearted) followed by in group D (4%) and group C, and group E (2%) respectively. While mortality remained zero in group A (control). Dressing percentage was better in group A (62.02%) followed by group E (59.2 1%), group C (58.45%) respectively.
Observing the effects of sulphaquinoxaline monensin and salinomycin on feed intake, weight gain, feed conversion ratio, mortality, oocysts count and dressing percentage in experimentally infected (coccidiosis) quails, it was concluded that sulphaquinoxaline has comparatively better results than monensin and salinomycin.
