摘要: A 11-year survey on helminth intestinal infection of horses was done in seven provinces southern Poland. 21,641 faecal samples were collected from different age, sex, breed and management system originating 84 farms. Age the major factor influencing cyathostome egg excretion, maximum being observed yearlings second year horses. Parascaris found mostly foals yearlings. The main for Anoplocephala access to pasture. level shedding (EPG) could be related sex (geldings had higher values EPG), (Thoroughbred EPG than other breeds), type farm (large farms others). change during anthelmintic treatment (from benzimidazole or pyrantel embonate avermectins) associated with lower EPG, this probably due partial resistance benzimidazole. seasonality (lowest November January included) (leaving pasture stable, October). influence climate significant but small, annual rainfalls average temperature negatively positively, respectively, high EPG.
