Observations were made on individual cases and on herds showing the effects of internal parasitism on the health and productivity of Toggenberg and Saanan goats. The clinical reactions varied markedly being influenced by the degree of infestation and duration of illness. Typical cases showed emaciation, anaemia, oedema, weakness and sometimes diarrhoea and death. Faecal analyses were dominated by strongyle egg counts which rose progressively throughout the study period. Overstocking led to some animals being at greater risk.
