EFFICACY OF DIFFERENT CONCENTRATIONS OF CALCIFEROL (VIT D2) AGAINST MUS MUSCULUS

No choice feeding test was carried out in the laboratory to evaluate the efficacy of calciferol at different concentrations (0.025, 0.05 & 0.1 percent) against M. musculus. It was observed that higher concentration 0.1% resulted in cent percent mortality after one day feeding with mean days to death being 2.1 where as 0.05% yielded 100 percent kill after three days of feeding and 0.025% yielded 50 percent mortality with mean days to death being 2.6 and 7.0 respectively. The symptoms of illness observed were sluggishness, pulmonary distress, polyurea and loss in weight.
