What is inoculant for silage?
In a nutshell, silage inoculants work by shifting silage fermentation in a direction that better preserves the crop. That happens when the lactic acid bacteria in the inoculant overwhelm the natural lactic acid bacteria on the crop.
What is a bacterial silage inoculant?
Silage microbial inoculants contain bacteria selected to dominate the fermentation of crops in the silo. Silage inoculants are divided in two categories depending on how they ferment a common plant sugar, glucose.
Why do they ferment silage?
Silage is pasture grass that has been ‘pickled’. It is a method used to preserve the pasture for cows and sheep to eat later when natural pasture isn’t good, like in the dry season. The grasses are cut and then fermented to keep as much of the nutrients (such as sugars and proteins) as possible.
What is the best silage inoculant?
The most common LAB in commercial inoculants are Lactobacillus plantarum, Enterococcus faecium, various Pediococcus species and other Lactobacillus species. Species and specific strains of LAB in commercial inoculants have been selected because they grow rapidly and efficiently, and produce primarily lactic acid.
Can you use too much inoculant?
You cannot over inoculate, so don’t be afraid of adding too much to the hole. The real danger will be that you will add too little garden soil inoculant and the bacteria will not take.
Can silage be made without molasses?
Silage may be prepared by substituting molasses for maize brain but the resulting feed is lower in dry matter and crude protein. The silage resulting without addition of either maize bran or molasses has poor nutritional value and storage characteristics.
How do you ferment silage?
Silage undergoes anaerobic fermentation, which starts about 48 hours after the silo is filled, and converts sugars to acids. Fermentation is essentially complete after about two weeks. Before anaerobic fermentation starts, there is an aerobic phase in which the trapped oxygen is consumed.
Can inoculant be applied after planting?
Although the bacteria may persist in the soil for 2 to 5 years, it is recommended that inoculation is done each time seed is planted to ensure inoculation. Inoculant, which is usually a mixture of the bacteria and peat, can be purchased and applied to seed.
