Colony Forming Units (CFUs)

Question:

“What is a colony forming unit and how many should a forage inoculant contain?

Answer:

CFUs are determined by taking a microbial suspension, making a series of 10-fold dilutions of this suspension and spreading a small amount of each dilution on petri dishes with a nutrient agar (“jelly”). … read more

Colony Forming Units (CFUs): Counting the Microbial Army

During ensiling there is an unseen battle between armies of microbes. High-quality forage inoculants supply armies of billions of elite, scientifically selected beneficial bacteria to help win this battle in your silage crops.

Using the right amount of bacteria can drive a rapid, efficient ensiling fermentation. These “fermentation aids” speed … read more

Target pH Levels in Silage

Silage pH varies depending on the forage to be ensiled, the dry matter (DM) level of the crop and the phase of ensiling — among other factors. While there are target pH ranges, this measure isn’t an absolute, fail-safe parameter and is somewhat dependent on the mixture of acids produced, … read more

Oxygen Scavenging

Question:

“Will oxygen scavenging antioxidants help make up for loose packing?

Answer:

Air is the worst enemy of silage production. In theory, you could add antioxidants to “mop” this up, but the amount required to achieve even distribution and scavenge all the available oxygen would be impractical. In reality, … read more

Reduced Heating and Spoilage

Question:

“Do all inoculants help reduce heating and spoilage?

Answer:

The simple answer is no. In fact, some heating is to be expected as a result of the fermentation processes that occur during ensiling. However, in the presence of oxygen, aerobic micro-organisms grow, which can cause significant heating and … read more
