Can I put hay cubes into a hay net for a hay bale?

Of course you can put hay cubes into the hay net for a hay bale. Due to the net shape (cylindrical), you will be able to place much fewer cubes than in the case of a cuboid shape net. The service nature will simply become more pronounced. However, we believe that regardless of the shape the hay net will have once full, the most important thing is that animals will eat slowly.
