Abstract

Holstein bull calves were used to study the anticryptosporidial effect of decoquinate*. Five calves served as controls and 5 were treated with 225 mg decoquinate in gelatin capsule per feeding until completion of the trial (8 wks). Calves were orally exposed with 8.5xHf Cryptosporidia oocysts at 4 days of age. Treatment with decoquinate did not prevent shedding of Cryptosporidia. It was shown, however, that treatment may delay the time from exposure to shedding, reduce the number of days shedding, and improve the stool consistency score.

Subsequent trials were conducted to compare the effect of varying levels of decoquinate on experimental cryptosporidial infections.

This presentation will include specific results of the trials and a discussion of the practical application of using Deccox® for ameliorating clinical cryptosporidial infections in neonatal calves.
