Lamb scours

I fed my two day old baby lamb the artificial colostrum for 24 hours and then switched to a lamb milk replacement. I switched cold turkey (sorry I misread the slowly section) and have been feeding her between 140 and 180 mls four times a day. The packet says three feeds of 233mls so this was my interpretation of introducing slowly. Can I stop feeding her milk for 24hrs if she is only 3 days. She is very lively and vocal still.
