Cryptosporidium parvum is a common cause of diarrhea in calves less than one month of age. Prevalence of shedding of C. parvum and clinical disease is high on many dairy farms. Control of cryptosporidiosis is difficult. There are currently no approved products in North America for prevention of this disease. In Europe, halofuginone lactate (Halocur®) is marketed for the prevention of cryptosporidiosis by reducing and delaying excretion of C. parvum oocysts and in preventing diarrhea. The objective of this study was to evaluate the efficacy of halofuginone lactate as an aid in the prevention of cryptosporidiosis in dairy calves.
