MICHIGAN BEET SUGAR 385 



^^■itll snjjiii- beefs and dry feed. Twelve cows wore divided into three 

 j;rou]»s of foni- eacli. After a proper preliminary period there was sub- 

 stituted for the corn silage, Avith one group beet pulp, with the other 

 sugar beets, while from the third the silage was removed and the loss 

 of dry ninttei- thus entailed su])])lied by additional hay and grain. All 

 the cows received daily not far from fifteen i)0unds of hay, ten ])ounds 

 of bran and five pounds of corn meal. Tliey ate in addition about twenty 

 pounds daily of sugar beets or forty to sixty pounds of the pulp. 



Cri'i^tu]) one was fed five weeks with pulp, then during one week the 

 pulp Avas gradually removed and for the following five weeks the cows 

 received the same ration of grain and hay as formerly, without the 

 pulp. Group two was fed dry feed for five weeks, then in an interven- 

 ing week pulp was gradually added, and given for the following five 

 weeks. To group three sugar beets were fed for the entire period of 

 the experiment. 



The four cows in group one consumed 4,623 pounds of ijulj); 1,075 

 pounds of hay, and 1,077 pounds of bran and corn. In Ihe five weeks 

 without i»ulp they ate 1.809 pounds of ha}', and 1,868 pounds of grain. 

 In other words, when given no pulp they ate 04 pounds of hay, 127 

 pounds of bran, and 64 pounds of corn more than when receiving it. 

 Tliis 385 pounds of dry feed may therefore be considered equivalent to 

 the 4.023 ])ounds of ]>ulp. While receiving pulp the cows gave 3,7:>3.0 

 pounds of milk, and 128.42 pounds of fat. In the five weeks without 

 pulp they gave 3,380.8 pounds of milk, containing 130.27 pounds of fat. 



Group two ate 4,840 pounds of pulp in five weeks, receiving it the 

 second five weeks of the test. With the pulp they ate 1,700 pounds of 

 hay, and an equal amount of bran and corn. In the first five weeks 

 without pulp they ate 1,780 pounds of hay, and an equal amount of 

 bran and corn. The cow^s ate, therefore in the i)eriod without pulp 148 

 pounds of grain and hay or 74 pounds of hay, HO pounds of bran and 

 24 pounds of corn more when not receiving pulp than when it was fed 

 tliem. 



In the first period of five weeks, without pulp, group two gave 3,456.8 

 pounds of milk and 128 pounds of fat. In the second period, with 

 pulp, the yield was 3,525.0 pounds of milk and 131.25 pounds of fat. 

 Combining the results of the two groups, one of which received the 

 pulp the first five weeks and the other the second, we find that when 

 having the j»ulp they ate 20S pounds of liay, 177 pounds of bran, and 

 tj;'> pounds of corn more than they consumed when eating the ;),403 

 pounds of i)ulp. The yields on pulp were 7,258.0 pounds of milk and 

 250.07 pounds of fat; in the periods without pulp the yields were 6,843.6 

 l)ounds of milk and 2.58.27 pounds of fat. As far as fat is concerned, 

 therefore, the yields with pnlj) and without may be considered indenti- 

 cal. Comparing the feed. then, it might ho assumed that the 0,463 

 pounds of i)iilp were as ellective as the 208 pounds of liay with the 172 

 pounds of Itran and 0:5 jxtunds of corn. 



A study of the changes in weights of the cows is intei-esting as bear- 

 ing upon the influence of the pulp on the body of the cow. Wilhout 

 taking up the cows individually it is enough for the purp(»se here to 

 record that group one gained 207 jmuiuls in weight on ])ulp and lost 

 17 pounds when the pulp was withheld. Group two lost 81 j)ounds
