Table I. — Acidity of sunflower silage, Idaho, iQig 



' Trace. 



DISCUSSION OF RESULTS 



Table I shows the kind and amount of acids found in the three samples 

 of sunflower silage. The acid fermentation of sample i does not appear 

 to be normal, for butyric acid is present in a large quantity while only a 

 trace of lactic acid is found. Sample 2 can not be classed as first-grade 

 silage, owing to the presence of butyric acid. Sample 3, however, at a 

 depth of 9 feet showed an acid fermentation similar to that found in good 

 corn silage, which is considered a typical fermentation. The abnormal 

 fermentation of samples i and 2 is no doubt due to the fact that 10 days 

 elapsed between the filling of the silo with sunflowers and the completion 

 of the filling with corn. This period of time allowed considerable air to 

 permeate the sunflower silage and favored the growth of organisms that 

 are responsible for an anbormal fermentation. The results on sample 

 3 show that under the proper conditions sunflowers will produce an excel- 

 lent grade of silage. 



COMPOSITION OF SUNFLOWER SILAGE 



Approximate analyses were made on the three samples. The results 

 are given in Table II. The average of these results, together with the 

 average of the results on 112 analyses of corn silage as given by Henry 

 and Morrison,* follows :
