Equine Obstructive Colic Associated with Heavy Parascaris equorum Infection

Anthelmintic efficacy on Parascaris equorum in foals on Swedish studs

BACKGROUND In the last few years stud farms have experienced increasing problems with Parascaris equorum infections in foals despite intensive deworming programs. This has led to the question as to whether the anthelmintic drugs used against this parasite are failing. This study aimed to investigate the efficacy of ivermectin, fenbendazole and pyrantel on the faecal output of ascarid eggs of fo...

New Studies Associate Equine Tapeworm Infection with Colic

• In a second study, prevalence of tapeworm infection in 157 horses was randomly evaluated at necropsy during a 12-month period. Anoplocephala perfoliata was identified in 27% of the horses, exceeding what fecal testing would indicate in many herds. Horses <2 years of age, perhaps due to immunologic susceptibility, were at greater risk of tapeworm infection than adult horses. The geometric mean...

Equine colic

The gastrointestinal tract of the average 1000 pound horse has a capacity of 120-200 liters. The transit time of ingesta through the system is rapid, with liquid leaving the stomach in about 30 minutes and entering the cecum in 2 hours. Liquid may then be retained in the cecum and large colon for a few days. Particulate matter passes at a slower rate than liquid. The equine stomach is small in ...
