The nutritional value of kudzu Pueraria lobata was evaluated as a potential animal feed. Randomly selected samples from natural habitats with Jacksonville area Alabama, USA were utilized in the study. Kudzu leaves showed significantly higher dry matter and crude protein content than the stems; whereas, ADF fiber was significantly lower in the leaves. However, NDF and total digestible nutrients TDN were similar in the leaves and the stems. The leaf part of kudzu was especially rich in CP 24.46% and met the requirements and recommendations for most ruminants. The TDN value for kudzu stem is 55.99%, which falls below but within the recommended range. Macronutrients concentration between the stem and leaf of kudzu, nitrogen, calcium, and magnesium showed a significantly higher in the leaf than the stem. However, phosphorous was similar in concentration in the stem and the leaf, and potassium was higher in the stem. In regard to the micronutrients, the only significant difference between the leaf and the stem was iron. However, iron, manganese, zinc, and copper were all above the recommended concentrations by the National Research Council. In general, kudzu can be considered a good source for animal feed, especially the leaf, which shows a higher value in most of the determined criteria in comparison to what was recommended by the National Research Council. This should provide a new outlook to kudzu, which has been considered a noxious weed and help in the utilization of kudzu in a positive way in the southern region of the US.
