Yes for the moment (they are milking goats?) that should be more than enough. My BT type nanny is on about 500g plus some sugarbeet per day (they are dry), then start to increase slowly from 6 -7 weeks onwards. By the end they probably should be on about 2kgs per day? Plus hay of course, mine need by then about 3-4 meals, as they will not eat large portions anymore.
My GG this morning left quite a bit of her mix, she is just starting to increase, due in 6 weeks.
