hope this helps,
i have two goats both 11mths old, a sannan and a toggenburg crossed.
i was feeding them to much concentrates along with the hay.
i cant exactly remember how much in pounds i was giving to them, what i thought was a nice bit was to much
im told on ere.
(hope im making sense)
i was told to cut down on the dry mix which i have.
they get about a cup full twice a day now, morning and evening.
i was told also too to mix it up with kwickbeet which soaks in water for 10min bulks up the feed in which they think they are eating loads

i think it is also high in fibre(i only think so)
mine love the dry mix food and now molly has a problem with her udder which some of us on ere are relating it to too much
concentrates.
so now i make sure they are getting loads of hay during the day time.
hope this helps you.
