In early autumn you are asked to examine some pedigree Suffolk rams which are in very poor condition (BCS 1.5, scale 1–5). The rams, purchased as yearlings, are grazing permanent pasture and were treated with albendazole (group 1 – benzimidazoles) in late spring and again 2 months later. Many rams have diarrhoea with considerable faecal staining of the perineum. The rams are bright and alert but in much poorer bodily condition than expected. A ram purchased last autumn is especially thin (BCS 1.0) and depressed with pale mucous membranes and slight submandibular oedema. The heart rate and respiratory rates are increased.
