We tried feeding measured amounts but it made no difference. When you have 23 kids that are bottle kids you stop measuring, after all mom goat doesnt measure how much kids get. When the kids wake up in the morning and mom is tanked up with almost a gallon of milk they stop themselves when they are full usually. Its more problematic if your only feeding a few times a day we feed about every 4 hrs from birth-2 weeks and then the windows get bigger as they start eatting hay. They have fresh available hay from day 1 and grain starting at 1 week.
