Anthelmintic sales in the highveld region of Eastern Transvaal.
Throughout a survey from 1991 to 1993 in the Highveld region of Eastern Transvaal, levamisole sales dominated in the sheep anthelmintic market. The macrocyclic lactone sales dominated in the cattle anthelmintic market, but were superseded by those of levamisole in 1993. The salicylanilides enjoyed the second highest demand in the sheep anthelmintic market. Anthelmintics were purchased throughout the year, but sales peaked in summer and autumn. When it rained in winter, sales increased during winter and peaked in spring. Eastern Transvaal Co-operative (OTK) sold 2,64 therapeutic doses per sheep during the driest year and 3,54 per sheep during the wettest year in the Highveld region. Only 24-29% of the cattle in the region could be treated with the anthelmintics sold by OTK for cattle. Total sales are estimated at double these figures.
