In vitro gas production and ruminal fermentation of glycerol, propylene glycol and molasses

Ruminal fermentation pattern and in vitro gas production was determined for three energy sources for ruminants, glycerol, propylene glycol and molasses with ruminal fluid from sheep. Substrates incubated were alfalfa, corn silage, glycerol (320 and 640 μl), propylene glycol (320 and 640 μl) and mola...

Zusammenfassung:	Ruminal fermentation pattern and in vitro gas production was determined for three energy sources for ruminants, glycerol, propylene glycol and molasses with ruminal fluid from sheep. Substrates incubated were alfalfa, corn silage, glycerol (320 and 640 μl), propylene glycol (320 and 640 μl) and molasses (320 μl). The greater volume of gas produced was observed at the highest dose of glycerol which also showed the slowest rate of gas production and the longest lag time ( P
