The article discusses the challenge of meeting the demand for animal nutrition during drought periods in the US Midwest and Southeast due to high input costs and severe weather conditions. It introduces hay production as a potential solution, a process that involves quickly drying forage to maintain nutritional value and allow long-term storage. This can improve zootechnical indices, reduce the need for concentrates, and provide a means of selling animals at profitable times. The article also mentions the importance of using the correct species for hay production and highlights the benefits of cynodon grasses and Panicum genus species. However, producing hay from legumes is more difficult due to the differences in dehydration speed between stems and leaves and the species' inability to support many cuts a year.
