I got this from a secondary school agric text book.

Beef Cattle Ration:
Maize: 24 kg
Groundnut Cake: 11 kg
Brewers Dry Grain: 59 kg
Bloodmeal: 2.5 kg
Dicalcium Phosphate: 3kg
Salt: 0.5kg
TOTAL: 100kg

Dairy Cattle Ration:
Maize: 33.5 kg
Groundnut Cake: 17 kg
Brewers Dry Grain: 42 kg
Bloodmeal: 2.5 kg
Dicalcium Phosphate: 3kg
Salt: 2kg
TOTAL: 100kg

Isn't this costly? I thought they need only grass.

They need mainly grass (and legumes for protein) but they'll do better if you supplement it with concentrate like this.
