What is fodder and how is it grown?
Fodder here means grain, such as barley, sprouted in trays with water for several days until it forms a mat of roots and short shoots. The mat is then fed fresh.
Systems range from stacked trays in a shed to enclosed units with lights and timers. All need clean water, good drainage and a way to keep temperature steady.
The attraction is year-round green feed in a small space, with no pasture needed. Be skeptical of marketing that promises a huge feed return from a small tray. Ask any seller for independent results from a university or extension trial, and read the small print about what was measured. Ask a nutrition specialist about the whole diet, not the fodder alone. A single feed rarely solves a ration problem.
Does fodder pay for itself?
Extension and university reviews have taken a careful look at this question. A common finding is that the sprouting process uses up some of the grain's dry matter, so the finished mat can carry less feed value per pound of seed than the seed you started with.
Feed value is not the same as water weight. A mat is mostly water, so compare animals' intake on a dry matter basis, not the weight in the tray.
Before you invest, work out the cost of seed, water, energy, labor and equipment, and compare it to buying hay or feed. Your extension office can help with the math. Some people find the labor is the real cost. Rinsing, moving and cleaning trays every day, including weekends and holidays, takes steady time that is easy to underestimate.
- Cost of seed
- Water and electricity
- Labor every day
- Equipment and repairs
- Replacement of trays and parts
What are the animal health concerns?
Moldy fodder can make animals sick. Warm, wet conditions that suit sprouting also suit mold, so cleanliness and daily attention are not optional.
Never feed fodder that smells sour or looks fuzzy. If an animal seems off its feed, shows bloating, scours or other signs of illness, call your veterinarian.
Changes in feed should be made gradually, and a vet or extension nutrition specialist can advise on the right plan for your species.
Which animals might benefit?
People feed fodder to goats, sheep, horses, poultry and rabbits. Small amounts may be useful as a treat or supplement, but it rarely replaces forage in a healthy diet for grazing animals.
Horses and other animals with special health needs should not be switched without a vet's guidance.
Poultry and rabbits often take fodder eagerly, but eagerness is not a nutrition test. If you keep a flock, ask your vet or extension poultry specialist how greens fit into a balanced diet. Any change to your animals' diet is worth a short call to your veterinarian or extension office first.
How do I keep a fodder system clean?
Wash trays between batches, change water, keep air moving and watch for mold. Sanitize equipment and dump spoiled batches well away from animals.
Keep rodents, birds and pets away from seed storage and the sprouting area.
Water use and drainage deserve a plan too. Wastewater from trays can be rich in organic matter and should drain away from wells, creeks and animal pens. Keep a written cleaning schedule on the wall, and mark each batch with its start date. A routine you can see is easier to follow when you are tired or busy. Never top up an old batch with fresh seed, which carries mold forward.
What are cheaper alternatives?
Good pasture, rotational grazing, quality hay and a tested mineral plan often cover most animals' needs at a lower cost. If green feed in winter is the goal, ask extension about stored forage options.
Try a small trial first, keep records and compare with your normal feed before committing money. If you want more feed from the same ground, ask extension about improving pasture fertility and grazing management, which often costs less than building a sprouting room.
What records should I keep during a trial?
Write down the seed weight, the days to grow, the weight of the mat, labor minutes and any spoiled batches. Also note how the animals look, how much hay they leave and any changes in manure or appetite.
After a month, compare your total cost per day with your usual feed cost. If the numbers do not favor fodder, you have saved yourself an expensive mistake, and your records will help a neighbor who asks.
Key takeaways
- Fodder is sprouted grain fed as a wet mat.
- Compare feed value on a dry matter basis.
- Mold is the main safety risk.
- Work out all costs before building a system.
- Pasture and hay are often cheaper options.
