I use a prepared mix (allan and page smallholder dairy goat mix) and use two baked bean tinsful added to soaked sugar beet (3/4 tuna tin dry) per bucket, two buckets between three of them, together with some chopped pony carrots or whatever else I can get in the way of veg in a third bucket. Plus as lib hay of course.
presumably that's twice a day MGM ?
Mine are ony a month into pregnancy so they get 1 half pint mug goat mix + 1 mixed flake + 1/2 mug soaked sugar beet, slice of diced wholemeal bread (don't know how that got introduced), a few whole oats (recomended by breeder) twice a day, also sliced carrots + any other veg, fruit, and of course hay ad lib, theyre also out whenever the weather is decent, (not today
) not forgetting minerals. I could probably be giving more sugar beet.
They'll get extra (warm) when the weather turns bad, and I'll make sure I start to increase the goat mix for the last 2 months for kidding.
As I understand it, feeding too much in the first 3 months creates big kids and possible kidding problems, other may think differently.
The kids get same mix but about half what the mums get, they sometimes leave it if I give more.
* just read the 'How much dairy nuts to feed'. looks a useful guide
