Goats: How much feed will a goat need per day

[Fnwarui]

.
What is the weight of your goat? Also, what do you mean by molaplus and comb mix?

Don't use grinded corn for goats to prevent acidiosis and death! When feeding corn to ruminants, be very careful! Read this: http://farmersjoint.com/thread-29041-lastpost.html.

when selecting goat feed, have profit in mind. So rather than feed them corn, why not feed waste products like pap chaff, brewers spent grain etc? Corn may not be that cheap.

 Thanks for the reply. 
The goats weigh between  45 and 60kg. By comb mix- I meant that that we grind the dry corn together with its comb (Maize comb) and molaplus is more like molasses.
