As above instructions are on the packet. Between 1-1.5l a day. I start off with 5 feeds a day of 200ml, then each week decrease a feed and up the amount. By week 4 they are on 2 x 500ml feeds a day, then week 5 I decrease to 2 x 250ml feeds a day, then cut out completely at 6 weeks. Introduce creep at about 10 days old, hay slightly later 2 1/2 weeks or so.
