Hay

Tridge summary

The Rural Development Administration (Chairman Cho Jae-ho) announced on the 18th that the National Institute of Livestock Science developed a hay production system using hot wind that makes hay with hot wind and applied for three related technologies for patents. The system can produce about 400 kg of hay per hour through a three-step process including dismantling, cutting, hot air drying, and compression packaging. The moisture content of hay can be adjusted according to the needs of the farmer, and it is characterized by high convenience in distribution and livestock feeding as it can be compressed and packed in units of 10 to 15 kg. In addition, it is a great advantage to be able to select a heat source according to the conditions such as gas, electricity, wood compressed fuel (pellet), cow solid fuel, and waste heat. The Rural Development Administration developed this system to overcome difficulties in manufacturing domestic hay (dry grass feed). Although hay is considered an essential food for ruminants such as cattle, production is difficult because the moisture content of horsetail must be lowered to below 20% under natural conditions for more than 4 days.
