One may use dried di.stillers* grains for bulk and also as a source 

 of protein, mixing by weight : 



(i) Yn distillers' grains, % Hour middlings, }{ corn meal. 



(2) y^ distillers' grains, J cottonseed meal and y^ corn meal. 



Malt sprouts, also a bulky feed, can be used mixed with other 

 grains by weight as follows : 



(i) )/( malt sprouts, % mixed feed, ^ gluten feed. 



(2) } malt sprouts, t corn meal, : gluten feed. 



It is better to prepare a considerable amount of the above mixtures 

 at one time, and then feed a definite quantity each day. 



In case corn silage is used as a distributer, the mixture may con- 

 sist by weight of : 



(i) 5/3 cottonseed meal. J/3 Hour middlings and I/3 corn meal. 



(2) Yz corn meal, Y cottonseed meal and Y ^^'^^ middlings or 

 rye feed.** 



Care must be taken to see that sucii combinations are well mixed 

 with the silage. 



Seven pounds is the usual quantity to be fed daily to cows pro- 

 ducing 10-12 quarts of milk. The richer the milk, the more food 

 needed. Because of the high prices of concentrates, and in locali- 

 ties where there is not a quick demand for milk, many feeders may 

 find it economy to use but 5 pounds of grain daily, and feed maxi- 

 mum amounts of roughage. f Heavy milking Holsteins generally re- 

 quire from 10 to 14 pounds of grain daily, depending upon the milk 

 yield. 



It is hardly possible to advise dairymen which ration would prove 

 the most economical, as prices are likely to change so quickly. 

 The price of wheat by-products will probably be relatively high the 

 present season, while corn, oats and their by-products ought to be 

 rather less than last season. If the consumer will take advantage 

 of the general suggestions made in this bulletin and put his own 

 mental powers into operation, he ought to arrive at a satisfactory 

 solution of the problem. 



* This ration, although a triHe wide, has proved quite satisfactory witli many feeders. 

 ** Many other grain rations may be found by consulting Bulletins 93-94-QS-99. 

 t Early cut hay. hay of peas and oats cut when in blossom, clover rowen and cprn 

 silage all help to keep down the grain bill.
