SOME ANALYSES OF SPOILED SILAGE 



W. G. Friedemann, 1917. 



The analysis of spoiled silage is different from that of normal 

 silage in the percentage of nitrogen, ash, and water-soluble acids. 

 The per cent of fiber, nitrogen-free extract and ether extract is 

 not given as it is only slightly lower in spoiled silage compared to 

 normal silage. 



The nitrogen is higher in spoiled silage because decomposition 

 has set in which was probaly caused by aerobic ammonifying or 

 nitrifying micro-organisms 



The ash content of spoiled silage is higher than that of normal 

 silage showing that destruction of organic matter has taken place 

 in spoiled silage. 



The per cent of water soluble acids is considerable lower in 

 spoiled silage as compared to that of normal silage. In one sample 

 of spoiled cane silage 89.32 per cent of the volatile acids was acetic 

 acid. 9.25 per cent formic acid and 1.43 per cent butyric acid. 

 Spoiled silage differs in the percent of those feeding constitutents 

 from normal silage which are materially aflfected by aerobic 

 (access to air) conditions or micro-organisms.
