Impact of management interventions on helminth levels, and body and blood measurements in working donkeys in South Africa.

摘要: Abstract The aim of the study was to determine effect alternative management interventions on levels nematodes and condition working donkeys in South Africa. Twenty-four adult ( Equus asinus ) within an area 200 km radius were randomly allocated eight paddocks. Two replicates each three together with a control group tested 16-month study. included monthly removal feces from paddocks where grazed, pre-winter moxidectin treatment, combination treatment fecal removal. influence different nematode egg counts, animal live weights, body scores general blood chemistry compared. In addition, herbage samples collected pastures paddock number third-stage larvae (L 3 per kg dry matter. At end worm recoveries counts performed animals following euthanasia. cyathostomes represented largest portion helminth species composition both larval cultures. Monthly alone did not significantly reduce L pasture consideration more frequent is discussed. Pre-winter resulted 100% reduction average reappearance period 42–55 days, reduced count for up 8 months, total burdens all treated donkeys. It also improved hemoglobin concentration, packed cell volumes some extent score
