Determination of protein content in selected plants methanol extract

An abstract of the research paper was presented to the Faculty of Veterinary Medicine, Universiti Malaysia Kelantan, in partial requirement for the course DVT
55204 – Research Project. Protein levels and ileal digestibility is critical in animal feeding. It is closely attributed to the animal's performance, which includes growth and efficiency. Plant-based proteins have consistently been one of the prime sources of protein that the livestock have ingested throughout the course of many years. The amount of protein in various plants can be determined by analyzing the protein content using selected plant extracts. This is a preliminary study to assess the protein content by using methanol extract of selected plants. Alpinia galanga, Curcuma spp., and Musa spp. leaves were used in this study. Using the Bradford method, Musa spp. leaves have the highest concentration of protein content, which is 261, 670 ng/mL, followed by A. galanga, which has 67, 670 ng/mL protein content, and Curcuma spp. has the lowest protein concentration, which is -20, 000 ng/mL. When the protein value is determined, the most suitable plant can be incorporated into the animal’s feed thus it will fulfill the daily nutritional requirements of the animals.
