This research explored an innovative way to improve animal feed by treating wheat straw with beneficial fungi. The study found that replacing one-third of regular wheat straw with fungally-treated straw in buffalo feed led to better growth and nutrition absorption in young buffalo calves. This has important implications for livestock farming, particularly in regions where high-quality feed is scarce. Impacts on everyday life: • Provides a cost-effective way to improve animal feed quality for farmers • Helps address the challenge of limited feed resources in developing countries • Offers an environmentally friendly method to enhance livestock production • Could lead to more efficient meat and dairy production • Demonstrates practical application of biotechnology in agriculture
