may be said, however, in explanation of this last point, that the lambs 

 given an opportunity to over-feed in the Cornell Experiment were not 

 in so good a condition as those in the previous experiment. The con- 

 clusion from both years is clear that if care is taken in keeping the pens 

 full the loss from over-feeding will be reduced to a minimum. 



Altogether, from December 15, 1910 to May 8, 191 1, 5 lambs were 

 lost from the number under experiment. 1 he following report was re- 

 ceived from the New York State Veterinary College covering their 

 autopsies :*

" In most of these animals there was found a congestion or inflam- 

 mation of the intestines. It is probable that most of them died from in- 

 testinal trouble, either catarrhal inflammation or hemorrhagic inflamma- 

 tion of the small intestines or cecum." 



SUMMARY OF OBSERVATIONS AT CORNELL UNIVERSITY, I9IO-II 



Cause of " apoplexy " 



Nothing can be added to the summary given on page 46, Bulletin 285, 

 as to the cause of " apoplexy." All the observations made in 1910-1 1 led 

 to negative conclusions, since no losses were sufifered from this disease. 

 The results of the feeding trials in both years show that apoplexy is not 

 caused from feeding rations as narrow as i :5. As for over-feeding, it 

 is advised to have care in this regard and to keep the pens full, with only 

 one feeding place in the rack for each lamb. 



Amounts of protein to feed 



The results at the Cornell Station bear out the results at the Shepard 

 farm. Rations with a nutritive ratio of i :5.3 gave relativelv better results
