82 HATCH EXPEEIMENT STATION. [Jan. 



E. Digestion Experiments with Sheep. 



J. B. LINDSEY, 



Digestion experiments were begun with sheep at this 

 station in 1893. Two series were publislicd in full in the 

 eleventh and twelfth reports of the Massachusetts State 

 Experiment Station, together with a description of the 

 method employed (see eleventh report). Since 1894 the 

 coefficients only of several series have been published in 

 dift'erent reports of the Hatch Experiment Station. In the 

 table which follows will be found the results of 185 single 

 trials with 73 feed stuff's, being the entire number of experi- 

 ments made between 1894 and 1902, excepting a few which 

 gave results of uncertain value, and hence were discarded. 

 The complete data for each experiment is on file at this 

 station. 



It is believed that the brief description of the various 

 feeds found in the table will suffice in most instances to give 

 a clear understanding as to their character. The following 

 additujnal information may prove of value : — 



Mixed f/rasf^es in the table includes Kentucky blue-grass, 

 red-top, timothy, meadow fescue, sweet vernal grass, and 

 alsike and red clover. Kentucky blue-grass and clover 

 predominated. 



J^nglish ha// is a term commonly used in many localities 

 for good upland hay, as distinct from salt and swale hays. 



Gluten vieal consists of the glutinous i)art of the corn, 

 mixed with the starchy portion, that cannot be recovered 

 by mechanical methods. 



* These experiments were made with the co-operation of a number of assistants. 

 Tlie results in the following table were comiiiled from the completed data by P. 

 H. Smith.
