ADJUSTING THE RATION 237 



Lba. Protein Carbohydra'Les Fat 



Timothy hay 12 .236 5.21 .168 



Corn silage R6 .345 5.15 .252 



Corn 4 .316 2.67 .172 



Oats 3 .321 1.51 .114 



Cottonseed meal 2 .752 .43 .192 



Nutrients provided 1.970 14.97 .898 



Nutrients required 2.245 14.55 .67 



In this the requirements are more nearly approached, but 

 the shortage in protein is still too great. 



If we shift the grain slightly to contain 3 pounds com, 3 

 pounds oats and 3 pounds cottonseed meal we have : 



Lbs. Protein Carbohydrates Fat 



Timothy hay 12 .236 5.21 .168 



Corn silage 36 .345 5.15 .252 



Corn 3 .237 2.01 .129 



Oats 3 .321 1.51 .114 



Cottonseed meal 3 1.128 .64 .288 



Nutrients provided 2.267 14.52 .952 



Nutrients required 2.245 14.55 .67 



In this case all three of the balances have been met very 

 satisfactorily. It will be noted that the balance of the nutrients 

 is almost perfect. No more feed is consumed in this case, but 

 more milk would be produced and a better physical condition 

 of the cow maintained. 



A very material amount of the balancing may often be 

 effected by means of the roughage, by the use of alfalfa or 

 clover hay. Thus we may feed a ration as follows:
