An experiment was carried out to compare the amount of milk obtained by lambs suckling at 1-hourly intervals with that obtained by lambs suckling at 4-hourly intervals during a 24 hr. period. Statistical analyses of the figures showed that the milk consumption of lambs suckling at 4-hourly intervals was not greater than that of lambs suckling at 1-hourly intervals.
