The researchers studied how treating wheat straw with a special fungus can improve its quality for feeding animals. They compared regular wheat straw diet with fungus-treated wheat straw diet in a lab setting. The fungus-treated straw diet led to higher gas production, better digestion, and increased production of beneficial substances in the animals' stomachs. It also reduced methane production, which is good for the environment. Overall, using this fungus treatment on wheat straw can make it a better food option for animals.
