Abstract

Faecal examination of 189 randomly selected rural calves in 12 villages of Rajoir upazila under Madaripur district of both sexes aged between < 3 months to 1 year old with or without the signs of gastroenteritis during three months periods from June to August 2003 revealed that 64.5 % calves were infected with Toxocara vitulorum. Significantly (p < 0.01) higher incidence of ascariasis was found in cross bred calves (64.28% - 75.67%) than in indigenous calves (46.66%). Age-wise analysis indicated that ascariasis was significantly (p < 0.01) prevalent in calves upto 3 months (81.35%) of age following by 3 to 6 months (70.58%) in comparison to > 6 to 12 months (41.93%) of age. Incidence of T. vitulorum infection was significantly (p < 0.01) higher in male calves (73.24%) than in female (57.92%). All the calves infected with ascariasis were diarrhoeic (100%), with pale mucous membrane (71.31%), rough body coat (74.59%) and emaciation (65.57%). Cachexia (19.67%) and erected hair (4.91%) were also recorded as clinical signs. Normal temperature was found in 95.08% calves while subnormal temperature recorded in 4.91% calves infected with T. vitulorum.
