 feeds as can be found in the local feed stores; note the guarantees on the sacks in

 between the cost and the digestible components, energy and feed-unit values. 1 

 Place the feeds in the order of increasing cost, according to the three methods 

 of comparison, and discuss the results obtained (Productive Feeding, Chap-
