The pulp differs from corn meal in having rather more of its 

 protein in the form of amids, in containing more ash and less 

 fat. Its carbohydrates are in the form of fiber, gums and sugar, 

 while the carbohydrate of corn meal is practically all starch. 



Our own experiment ^ on the digestibility of the molasses 

 beet pulp carried out with two sheep is the only one on record. 

 It shows it to be 85 per cent, digestible, as against 77 per cent, 

 for the plain pulp. These results, however, arc hardly com- 

 parable, as the latter figure represents the average of German 

 experiments. In any case the molasses pulp has a high rela- 

 tive digestibility, and is not very much inferior in this respect 

 to corn meal. 



Molasses Pulp for Dairy Stock. 



Billings " compared the dried molasses beet pulji with the 

 plain dried J^ulp, and secured a trifle more milk with the 

 former. He likewise compared it with hominy meal, and se- 

 cured some 4 per cent, more milk as a result of its use. 



Our own experiment, made in 1003,^ comparing it with 

 corn meal, resulted in an increase of 5 per cent, of milk when 

 the corn meal was used. It is believed, however, to be a satis- 

 factory carbohydrate food, slightly superior in its nutritive 

 effect, as well as in palatability, to the plain dried pulp.
