BookPublisher: 1993Subject(s): Department of ParasitologyDDC classification: 0345,T Dissertation note: The study was conducted to evaluate the efficacy of anticoccidial drug coxeva (a mixture of 80% sulphadimidine and 8% diaveridine) and its effects on body weight, growth rate and feed convertion ratio were studied. For this purpose 120 day old broiler chicks were reared upto the age of 4 weeks. At the end of 4 weeks the birds were randomly divided into four groups A, B, C, and D, each group containing 30 chicks. The birds of each group were weighed. The group B, C and D were infected with 50,000 sporulated oocysts of Eimeria tenella. While the group A was left uninfected and kept as control on the 6th day after the appearance of clinical symptoms of caccal coccidiosis, the group C and D were medicated with coxeva (the group C for five continuous days and group D for three days on 2 days off three days on), the group B was left as infected control. The daily oocysts count per gram of faeces were taken upto the end of experiment which was zero in group C on 10th day and in group D on 13th day the oocysts were at their peak (5,20,000) on 15th day of inoculation. The body weight was recorded at the end of each week throughout the experiment which showed significant difference in group B and group A, C and D . The feed consumed by each group was recorded on daily basis and growth rate was recorded at the end of each week. The analysis of variance revealed significant difference in feed consumption and growth rate in group B and other groups. The feed conversion ratio was recorded for each group at the end of each week which showed non significant difference among group A, B, C and D. The drug was also evaluated for its modes of administration (continuousand intermittent) and found no significant difference in both modesof administration. The mortaility was recorded which was five birds (16%) in group B. The drug proved hundred percent effective against caecal cocidiosis in broiler chicks.
