Abstract

A study to evaluate alternative health interventions for the control of sarcoptic mange and gastro-intestinal nematodes in smallholder pig herds was carried out in Kikuyu Division of Kiambu District, Kenya between August and December 2000. A total of 40 herds were randomly allocated, by a simple random strategy, to 3 treatment groups and 1 control group. Each group comprised of 10 herds. Herds in group 1 (control) were treated with a placebo, physiological saline. In group 2, ivermectin was used, while in group 3, Piperazine hydrochloride and an acaricide (amitraz) were used, respectively. In group 4, levamisole hydrochloride and amitraz, were used respectively. The anthelmintic activity of ivermectin was not different (p>0.05) from that of levamisole. The proportion of pigs positive for mites was not different (p>0.05) between the ivermectin and the amitraz treatment groups. The overall costs per pig for the treatments were US$0.50 for the ivermectin treatment, US$0.31 for the piperazine/amitraz combination treatment and US$0.26 for the levamisole/amitraz combination treatment. Amitraz/levamisole drug combination was the most cost-effective against sarcoptic mange and gastro-intestinal nematodes of pigs in the studied smallholder herds.
