about to begin the Sucrene period proper. It may be safely assumed, 

 judging from observations made at the time and from data secured, 

 that the bran and gluten ration produced rather better results than 

 the Sucrene ration ; further deductions cannot be drawn. The 

 above figures in no way reflect seriously upon the character of the 

 sucrene feed. They show that combined with a good quality of hay 

 and with corn and soy bean silage, this feed was capable of making 

 a fairly satisfactory showing. To its deficiency in digestible protein 

 and in total digestible matter and to the presence of weed seeds°^ is to 

 be attributed its inferiority to a combination of bran and gluten. 



MACON SUGAR FEED VS. WHEAT BRAN AND GLUTEN FEED. 



Macon sugar feed had the same general type of composition as did 

 other feeds of this class. It was lower in protein than the average 

 (13-54 per cent.) 



Four cows that had been used in second experiment just des- 

 cribed, were employed in this experiment which extended over a 

 period of four weeks, and was conducted by the reversal method. 

 The method of caring for the cows and sampling of feeds and milk 

 was the same as described under the experiment with molasses. 



The Macon feed was unusually dry so that in order to make a 

 fair comparison, an equal amount of dry matter of this feed was com- 

 pared with an equal amount of dry matter of bran and gluten"'. A 

 nice quality of hay and rowen constituted the basal ration. The 

 animals ate the daily rations clean and no disturbances were noted 

 during the entire experiment. 



YIELD OF MILK AND MILK INGREDIENTS (Pounds). 



-'2 Recent samples show that the weed seeds are mostly ground, which would enable them 

 to be more or less digested, and would prevent their distribution in the manure.
