Topping clamps of maize or grass silage with a layer of fodder beet can provide a convenient total mixed ration without the challenges often associated with ensiling this mix. This innovative method, developed by plant breeder and seed supplier KWS, involves spreading a 1-2m layer of chopped beet on top of the pit, creating what is known as “brownie-style” ensiling.
According to grass and forage consultant Marc Jones, this approach enhances the feed value as each crop can be harvested at its optimal stage, reducing losses that may occur when moving forage between different clamps. The effluent from the beet, which is rich in sugar, is absorbed by the silage instead of being lost, adding value to the feed.
One of the key advantages of this method is that once clamped, beet can be fed throughout the year. This is a significant improvement over traditional storage methods, where beet would only last around three months in stacks and could be affected by winter frost.
In terms of cost, clamping beet with forage can be a more economical option compared to using other feed sources with similar nutritional profiles. Fodder beet can replace concentrates or barley in a ration at a lower cost, making it a cost-effective alternative to traditional feed sources.
By combining the sugars in the fodder beet with the starch and fiber in maize, a high-energy feed is created. This approach has been successfully implemented by Danish farmers, who have been experimenting with co-ensiling beet with silage to improve feed efficiency.
The process of ensiling beet with forage involves chopping the beet into small pieces, ensuring a good mix of sizes for optimal ensiling. The beet should be ensiled at around 25% dry matter content and stored for at least two to three weeks before ensiling to allow for proper maturation and reduction of effluent production.
Overall, the “brownie-style” ensiling technique offers a simplified and efficient way to incorporate beet into a total mixed ration, providing farmers with a versatile and cost-effective feed option for their livestock.
