In the JHacidificationNH4 + plant liquid manure is mixed with sulfuric acid to adjust the pH value from about 7 to 5-6. When the pH value of the manure is lowered, ammonia is converted to ammonium. Ammonium does not evaporate, and therefore harmfull ammonia volatilization is reduced – by up to 50 % from cow stables.

Sand in boxes is widely used in cattle farming. The great advantage of sand is its weight. Sand is a heavy material and quickly establishes a flexible and stable bed which is formed after the cow. Sand has a good effect on the well-being of the cows since sand inhibits the growth of bacteria and liquid is transported away from the surface of the bed. Sand leaves the cow to rest long and thus contributes to good health in the stable.
Bale opening device: The ball opening device is available for different bale sizes. The bales can be loaded from three sides. In the device alone fits one bale of straw, but the device can be combined with an additional feeder table, on which several bales can be stored. On the device the JHminiStrø CUTTER can be mounted to cut the straw before it is filled into the robot.
Roughage for organic egg-laying hens and sows. Experiments show that the feeding of roughage reduces feather pecking and cannibalism among egg- laying hens significantly. The hens will be more healthy and more productive. Feeding of roughage like for example corn silage to sows provide better saturated and thus less stressed animals.
The system JHminiStrø automatically distributes different bedding materials such as straw, hay, sawdust, sand and dried manure solids. In addition, the system is ideal for distributing roughage to sows and/or organic chickens. The system can be installed in both existing and new stables. JHminiStrø robots are small, but hardworking and distributes material several times a day in contrast to other systems.
