In general, though, acids are not widely used because they are very corrosive and unpleasant to handle. Other trials in Manitoba have shown anhydrous ammonia to be very effective in preventing moulds and yeasts in both hay and silage. Anhydrous ammonia is a non-protein nitrogen source which increases the nutritive value and the digestibility of the forage to livestock. The use of granular urea on silage can perform the same function. Even distribution of the product is essential.
Most biological products have a provisional licence for sale in Canada.
Products on the marketplace with a temporary registration will be allowed a period of up to one year to substantiate label claims or else be removed from the marketplace. At the present time, many bacterial inoculants are being evaluated by research institutions and universities in Canada. Insufficient research data is available at this time to discuss product effectiveness. For more information, contact your local Ag Rep or Forage Specialist at Manitoba Agriculture and Food.
