The duration of excretion of Toxocara vitulorum larvae in the milk of buffalo cows determines the optimum time for treating calves. Studies on 10 cows showed that a few larvae occur in the colostrum of some cows before the calf has suckled, but most are present from the day after calving and for a further five days. From day 9 onwards, very few larvae were(More)
Eggs of Toxocara vitulorum were harvested from the feces of infected buffalo calves and embryonated in vitro. Optimum conditions for hatch and culture of the second-stage larvae were determined. Maximum hatch of larvae occurred from eggs that were decoated by treatment with saturated Ca(OCl)2 for 16-24 min followed by treatment with CO2 and incubation at 37(More)
The levels of antibody to the excretory/secretory antigens of the infective larvae and adults of Toxocara vitulorum were measured by gel precipitation and ELISAs in the serum and colostrum of 12 buffalo cows naturally infected with T vitulorum and in the serum of their calves. The antibody levels were compared with the extent of T vitulorum infection as(More)
Currently there are over 164 universities in 31 countries offering undergraduate degree programs (or as an emphasis) in agricultural engineering (AE). Many of these programs are not offered through engineering colleges and thus are not accredited as engineering degrees. Some of the AE curriculums have less than 50% of the coursework in engineering and as a(More)
