Lallemand: Innoculant tips for specific silage challenges

 

1. Independent, scientific research. The trials should validate the efficacy of the product at the application rate stated on the label and, ideally, be published in a reputable journal or presented at a scientific conference. In addition, make sure the research was performed in the specific crop you are going to ensile. 

 

2. An application rate of at least 100,000 CFU per gram of forage for fermentation enhancement, the minimum level recommended by university researchers. If facing an aerobic stability challenge, or threats from yeasts and molds coming from the field, producers should consider using a product containing high dose rate Lactobacillus buchneri 40788, as reviewed by the FDA. 

 

3. Contains enzymes at guaranteed levels, to help the bacteria drive a rapid, efficient fermentation. 

 

4. Shelf life and storage indications on the product label need to be followed to help ensure products remain live and viable. Inoculants are living organisms, and appropriate packaging and handling helps guard them from heat, moisture and air. 

 

5. The product format is suitable. For example, dry granular application may be less effective, especially in higher dry matter (DM) crops. 

 

6. Packaging that helps maintain the product viability, such as foil laminate pouches with a barrier against moisture and oxygen. 

 

Last, but not least, take into account your silage history and the challenges you face. Generally, high protein crops present a greater fermentation challenge, while high starch crops have greater aerobic stability issues. Be aware of specific challenges due to weather - such as crop DM, drought, hail, etc. - crop maturity and factors such as insect damage and field disease. 

 

There are specific strains that are proven to help drive a fast efficient front-end fermentation and strains that help support aerobic stability. Some products provide an effective combination proven to achieve both these goals, Dr. Schmidt notes.
