Biological Activities
Compounds
Conditions
Panicum repens is identified as a plant species used for the treatment of dysfunctional cattle organs. This specific therapeutic application was documented during a study of ethno-veterinary practices in the Punjab Province of Pakistan. The use of this particular grass represents a novel ethnoveterinary finding within the recorded data. By addressing organ dysfunction in livestock, the plant serves as a significant component of local traditional medicine. Such findings highlight the specialized role of this species in managing animal health disorders.
Preparations
Panicum repens is prepared as stalks to serve as a substrate supplement for the cultivation of the medicinal mushroom Auricularia polytricha. These stalks are incorporated into a sawdust basal substrate at various proportions, including 30%, 45%, and 60%, to enhance biological efficiency. Research indicates that using 60% Panicum repens stalks as a supplement can result in a high biological efficiency of 148.12%. Furthermore, the inclusion of these prepared stalks helps increase the protein content of the resulting mushroom fruiting bodies compared to a control group. Consequently, the use of Panicum repens stalks is a feasible method for partially replacing sawdust in mushroom cultivation.
