ECONOMICAL CHOICE OF PROTEIN FEEDS. 



Feeding trials with dairy cows have shown that when 

 alfalfa or clover hay and silage are fed as roughages there 

 is little difference in the efficiency of gluten feed, oil meal 

 or cottonseed meal as sources of protein. If you are feed- 

 ing a good quality roughage it is advisable in making a 

 ready mixed ration to use the protein rich feeds which fur- 

 nish the digestible protein at the lowest cost. When lin- 

 seed oil meal furnishes more pounds of protein per dollar 

 more of it should be used and when cottonseed meal fur- 

 nishes more pounds of protein per dollar more cottonseed 

 meal and less linseed meal should be used. Study the analy- 

 sis of the feeds and buy economically. It ivill pay! 



COMPARATIVE VALUES OF COTTONSEED MEALS. 



Eighteen samples of cottonseed meals were analyzed 

 A com.parison of the analyses and selling prices shows that 

 the higher the analysis the cheaper the cost of protein is 

 per pound. Table Number 5 shows the number of samples 

 analyzed under each percentage, the price per 100 pounds 

 and the average number of pounds of protein that one dol- 

 lar will buy in each case.
