Summary

Estimates were made of the intake of strongyloid infective larvae by sheep at pasture by the recovery of larvae from samples of herbage collected through oesophageal fistulae.

All herbage eaten was not recovered through the fistula but few larvae were lost in the process of mastication and swallowing. More larvae could be recovered from macerated than from undamaged herbage.

Samples were obtained from different sheep on different days and at different times during the day and the variance components associated with these factors were estimated from seven sets of observations. The contribution to variance differed widely for each factor with the major contribution coming from time changes in the differences between sheep.

The authors wish to thank Mr G. W. Major for valuable technical assistance throughout these studies.
