July 9, 191 7 Microorganisms and Heat Production in Silage

forage, that saturated with chloroform and that heated, exhibited no 

 characteristics of silage. The total acidity determinations noted on 

 figures i, 7, 8, 9, and 10, respectively, indicate the fermentation ability 

 of the various types of forage treated differently.

 chloroform and heat, respectively. 



Heat production was only observed in the untreated and inoculated 

 forage. The treated samples offered no indications of heating. The 

 differences noted in the comparative amounts of heat production are 

 probably due to the varying amounts of oxygen incorporated in the jars 

 at the time of siloing the forage.

The temperature curve representing the chloroformed forage followed 

 the curve of the heated forage and that of the outside temperature very 

 closely. However, there will be noticed a rapid rise of the treated- 

 forage curves the first few days, which at the first glance might signify 

 heat production. This increase stops at a temperature corresponding
