Conteúdo: 	Clun Forest sheep, aged between 3 and 18 months and worm-free from birth, were given a single dose of 25 000 infective larvae if the nematode Haemonchus contortus. The host animals were killed between 4 and 100 days after infection and the nematode populations were examined to determine size and composition. The relation between worm body len- ght, dry weight and age was studied and growth curves were constructed . Variations in the sex ratio for infections of different ages were noted. No evidence was found for a re- lation between rate of growth and population density. The rate of expulsion was determi- ned and its variability discussed.
