NHU is committed to continuously improving product energy efficiency and reducing carbon footprint throughout the product lifecycle. We start from the very beginning, the innovation and R&D of energy-saving technologies. Studies show that low-protein diets can significantly reduce fecal nitrogen excretion. Every 1% reduction in the intake of crude protein can reduce the excretion of ammonia by 10%, dietary crude protein by 2%, and nitrogen by 16%. Adding our methionine products to animal feed can balance daily ration of amino acids and reduce crude protein level. It helps to significantly reduce nitrogen excretion, cut greenhouse gas emission, and effectively improve the breeding environment without compromising animal production performance.
