Using agricultural straw and other agricultural and forestry wastes as raw materials, modern biological technology is used for deep processing to produce high value-added, non-polluted xylo-oligosaccharide feed additives. This international pioneering work developed by Nanjing Forestry University was recently launched. Nanjing passed the identification of major scientific and technological achievements organized by the State Forestry Administration.
Xylo-oligosaccharides are an emerging functional food additive in the world in recent years. Due to technical reasons, the use of xylo-oligosaccharides in feed has not been developed.
Under the leadership of Prof. Yu Shiyuan, the president of the school, the Institute of Biochemical Engineering of Nanjing Forestry University, after years of hard work, successfully developed xylo-oligosaccharide feed additives for the first time at home and abroad. Through the large-scale breeding test of laying hens, only 1 minute and 5 centimes worth of xylo-oligosaccharide additives are added per kilogram of chicken feed. Egg production can increase by 5% to 7%, and cholesterol in eggs can be reduced by 30% to 60%. And the resistance of the chicken was increased, the mortality rate was decreased by 6%, and the dose decreased by 15% to 30%; 1000 chickens increased gross profit by 1890 to 3460 yuan per year, and increased by 17% to 28%. Xylo-oligosaccharides have also achieved remarkable results in experiments in special aquaculture such as ducks, pigs, and fish and shrimps.
The successful development of xylo-oligosaccharide feed additives is of great significance in reducing drug residues in livestock and poultry products, increasing the ability to export foreign exchange, and protecting human health.
