Goats: How much feed will a goat need per day

[Henlus]

 Nice read. 

Kindly advice on how I can make total mix ratio (Trm) for goats using hay, nappier grass, molaplus and grinded corn and comb mix.

Please also advice on the amount of feed in kg that each goat should be fed.

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, soyabeans hull etc? Corn may not be that cheap.
