218 THE CREAMERY PATRON'S HANDBOOK. 



cows were kept on a pasture only, and three were given grain. The lot on 

 pasture only decreased from 20.60 pounds to 17.88 pounds of milk and .86 

 pounds to .77 pounds of fat, and the per cent, of fat increased from 4.19 

 to 4.29 pounds from June 8 to September 21. During the same period the 

 grain fed lot decreased from 20.55 pounds to 13.09 pounds of milk, and 

 . 86 to . 65 pounds of fat, and increased the per cent, of fat from 4. 18 per cent, 

 to 4.95 per cent. The final result was too close to draw a definite con- 

 clusion. 1 This work was duplicated and reported in bulletin 22, when 

 Lot I produced a total of 118.4 pounds of butter fat and Lot II, 119.72 

 pounds. Lot II consumed 2,822 pounds of wheat bran and cottonseed 

 meal. The experiment was again repeated and reported in Bulletin 

 36, at which time the grain feeding showed better because of the short 

 pasture. 



PASTURE ALONE. For the production of milk there is no feed so cheap as 

 grass. 2 Changing cattle from barn feeding to pasture resulted in more 

 and better milk. 3 



DROUTH caused a great shrinkage in milk. 4 



MISCELLANEOUS. The following rations (1) cottonseed, corn meal and 

 wheat bran, (2) peas and barley, and (3) linseed meal, corn meal and wheat 

 bran, were alternated through three periods. There was less variation 

 because of the changes of feed than is often seen in uncommon feeding; 

 the quantity was diminished slightly in passing from the first to the sec- 

 ond, and increased in passing from the second to the third feeding. The 

 melting point of the butter and the percentage of olein was lower in 

 the second than in the others. 5 



HEAVY GRAIN. In general it may be said that the limit to assimilate 

 a heavy grain feed and respond in milk produce is dependent upon the in- 

 dividuality of the animal. 6 



LIGHT AND HEAVY MEALS. Light foods as bran, are often as good, 

 weight for weight, as heavier for quantity and quality of milk, but seems 

 to cream less thoroughly than from heavier meals. 7 



HEAVY GRAIN had the effect ol decreasing the hardness of the butter. 8 

 NUTRITIVE RATIO. No relation was found between the nutritive
