On Sheet1, you will find feed cost and feed nutrient composition for the following 600-lb replacement heifer ration:

Ingredient	Ration composition, % (dry basis)
Corn grain, cracked	48.75
Alfalfa hay	30.00
Forage sorghum hay	20.00
12-12-12 Mineral	1.00
Salt	0.25
Total	100.00

Determine dietary concentration for all components TDN to vitamin E of the above ration. This is the same exercise you did in lab 1 and question one of lab 2. Ration composition and nutrient concentrations are all on a dry basis.

Calculate cost of feeding a heifer daily ($ of feed/day). Assume heifers will eat an average of 17 lb of DM daily. Remember, price of feed is on an as-fed basis and ration percentages are on a dry basis. You will need to convert dry consumption to as-fed consumption.
