DDGS–Rice is a highly valuable feed ingredient known for its exceptional nutritional profile and sustainability. With a protein content ranging between 26–30%, it serves as a strong supplement for livestock growth while providing essential amino acids such as lysine and methionine that support muscle development and overall health. Rich in metabolizable energy, it is well-suited for poultry and cattle, offering a balanced mix of protein, fat, and fiber for sustained energy release. The addition of rice enhances texture, taste, and digestibility, leading to better feed intake and reduced wastage as animals naturally prefer this blend. Compared to conventional protein sources like soybean meal or maize, DDGS–Rice is a more affordable alternative, helping farmers reduce overall feed costs without compromising productivity. Moreover, as a by-product of ethanol production, it represents an eco-friendly and sustainable choice that reduces dependence on conventional crops while promoting circular agriculture.
