Stable silage depends on rapid lactic acid fermentation

Rapid drop in silage pH sets stage for reduced clostridia, E. coli growth.

A rapid pH drop is the first requirement to produce quality silage. When the pH doesn’t drop quickly, it allows other microbes like clostridia and Escherichia coli to grow.

“Clostridia occur naturally in soils, and they get into field crops naturally at harvest,” Dr. Bob Charley, forage products manager at Lallemand Animal Nutrition, said. “If clostridia get going, they use up sugars and lactic acid and convert them into butyric acid, which causes some serious feeding issu
