Litters of piglets were given ad libitum access to a sow-milk replacer (SMR) during lactation (200 g SMR per I) and the 1st week after weaning (100 g SMR per I). Weaning was at 3 and 4 weeks of age in the first and second studies respectively. SMR was readily consumed but was associated with a high incidence of scouring, reduced intakes of creep food, and (in one study) increased mortality. There was a trend towards increased litter weight in the 4-week weaning study only.
