In the kidney of Ram III the same kind of pigmentation occurred as in Ram VI. 

 Ram III was fed Mangels. No calculus was present. 



Miss S. Hartzell, who investigated the chemistry, reports as follows : 



A post mortem examination of several valuable animals which the Experiment Station 

 lost showed that renal calculi were present. This resulted in the metabolism experiment 

 which was conducted by the Animal Husbandry Section in co-operation with the Chemical 

 Section of the Experiment Station. 



Thus far 42 rams have been used in the experiment, of which 11 were fed hay and 

 corn; 9 were fed hay, corn and ensilage; 11 were fed hay, corn and mangels; 11 were 

 fed hay, corn and sugar beets. In the case of those which were fed hay and corn, and 

 also of those which were fed hay, corn and ensilage, the bladders and kidneys were normal 

 while the results were the reverse in the case of those which were fed sugar beets or 

 mangels along with the hay and corn. The sugar beets and mangels had the same effect 

 The kidneys were larger than normal, the gall bladders were distended, the bladders wer 

 enlarged, often very much so, and in several cases the heart was enlarged. The kidneys 

 in all cases were of a pale color. Three animals died during the experiment. The bladder 

 of one was highly inflamed while in the other two the bladders contained calculi which 

 were too large to pass thru the urethra. The kidneys of two of the animals were broken
