Abstract:
The serum proteins of worm-free crossbred lambs were found to vary over a period of 10 weeks.

The total serum proteins of infested sheep remained static or decreased slightly over the period of observation. There was a marked hypoalbuminaemia (measured in grams per cent.) in the infested lambs. The
