This {able does not assume to represent average conditions in any 

 district of the country, but shows how any stockman may compare the 

 relative economy of the different available feeds at local prices. The 

 last column shows clearly that, for the feeds given and with prices as 

 stated, com is by far the cheapest source of total digestible nutrients 

 among the concentrates. Of the roughages, corn silage supplies total 

 digestible nutrients most cheaply, followed by clover hay. For balanc- 

 ing a ration low in protein, cottonseed meal will furnish digestible 

 crude protein at 4.59 cts. per pound, linseed meal at 5.63 cts., dried dis- 

 tillers' grains at 6.92 cts., gluten feed at 6.94 cts., red clover hay at 

 7.89 cts., and wheat bran at 10.00 cts. In supplj^ing protein these 

 feeds will of course also furnish carbohydrates and fat as well, which 

 are included in the total digestible nutrients. 



A corn-belt ration for milk production. — From the feeds listed let 

 us now formulate the most economical ration which will be satisfac- 

 tory for a 1,200-lb. cow yielding daily 30 lbs. of 3.5 per ct. milk. For 

 this cow there will be required, according to the IModified Wolff-Leh- 

 mann standard (Appendix Table V), a minimum daily allowance of 

 2.31 to 2.67 lbs. digestible crude protein and 18.99 lbs. total digestible 

 nutrients. The ration should contain from 25 to 30 lbs. of dry matter, 

 and should have a nutritive ratio no wider than 1 :6.1 to 1 :7.2.
