82 HATCH EXPERIMENT STATION. [Jan. 



E. Digestion Experiments with Sheep. 



J. n. LINDSEY.' 



Digestion experiments were begun Avith sheep at this 

 station in 1893. Two series were published 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 

 different reports of the Hatch Experiment Station. In the 

 table which follows will be found the results of 185 single 

 trials with 73 feed stuffs, being the entire num])er 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 

 additional information may prove of value : — 



Mixed grasses 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. 



English liay is a term commonly used in many localities 

 for good upland hay, as distinct from salt and swale Im^s. 



Gluten meal consists of the glutinous part 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. 

 The results in the following table were compiled from the completed data by P. 

 H. Smith.
