Efficacy of slow-release albendazole capsules in controlling lungworms and gastro-intestinal nematodes in red deer (Cervus elaphus).
One hundred and fifteen young red deer (Cervus elaphus), heavily infected with lungworm (Dictyocaulus viviparus) and lightly infected with gastro-intestinal nematodes, were divided into three groups. One group of 50 animals was treated with one adult sheep dose of a slow-release albendazole capsule, another group of 50 was dosed orally five times with liquid albendazole and 15 were left as untreated controls. The capsule eliminated faecal lungworm larvae during the 103-day trial period. There was a highly significant difference in faecal larval counts between the capsule-treated and control group. Over the trial period, the mean body weight gain of the untreated, liquid albendazole and capsule-treated animals was 0.1 kg, 4.5 kg and 7.8 kg respectively.
