of the various cattle foods used. The following summary includes the 

 more important results: ' 



Molasses feed vs. mixed grain for cows. 



The results of the experiments indicate that molasses feed and mixed 

 grain (barley and oats) possess the same feeding value, pound for pound, 

 for milch cows when fed in similar food combinations as in these experi- 

 ments, viz, with oil cakes, roots, hay, and straw. Even when 3.3 lbs. 

 of molasses feed was fed with 55 lbs. of mangel- wurzels per day, no 

 deleterious effect could be traced in the digestion of the cows. 



Sugar-beet residue and molasses feed vs. mixed grain. — In a single 

 experiment at the Ourupgaard estate during 1895-90 with 28 cows 

 divided into 2 even lots, 2 lbs. of n ixed grain, 2 lbs. of molasses 

 feed, and 20 lbs. of sugar-beet residue were fed to 1 lot, and 2 lbs. of 

 molasses feed and 44 lbs. of beet residue were fed to the other lot. 

 All the cows received oil cakes and hay in addition. Hence 24 lbs. of 

 sugar beet residue was compared with 2 lbs. of mixed grain (barley, 

 oats, with a little peas, grown together). The yield and composition 

 of the milk produced and the weight of the cows indicated that the 

 feeds mentioned were of about similar value, in the proportions fed. 



The effect of food on quality of milk. — The general conclusion on this 

 point to which these Danish cow-feeding experiments have led is given 

 as follows: In the comparative feeding experiments with milch cows, 

 now continued during 9 consecutive years, in which about 2,500 cows 

 divided into 218 lots on 12 estates in different parts of our country 

 have been included, it has constantly been found that the changes 

 made in the system of feeding the different lots have been practically 

 without effect upon the chemical composition of the milk. In these 

 experiments, barley and oats have been fed against roots, oil cakes, 

 wheat bran, wheat and molasses feed; mixed grain and oil cakes have 

 been fed against roots, and grain and roots have been fed in addition 

 to the regular rations given. It must be remembered, however, that 

 the changes in the feed were never so great as to make the resulting 

 rations abnormal (according to Danish feeding practice). — f. w. woll.
