Simulated Digestion System (SDS III)
The most cutting-edge technology of simulated digestion for monogastric animals
SDS III: Fast, Accurate, and Repeatable Feed Evaluation
Traditional feed evaluation and enzymolysis testing are time-consuming, costly, and influenced by various factors such as climate, animal health, and feeding conditions. How can we achieve a faster, standardized, and reliable solution?
SDS III Simulated Digestive System, co-developed by the Institute of Animal Science, Chinese Academy of Agricultural Sciences and Hunan Zhongben Intelligent Technology, is an automated bionic system that precisely replicates the digestive processes of monogastric animals, providing a scientific and standardized solution for feed evaluation.
✅ Accurate determination of effective energy in feed with high repeatability
✅ Comprehensive simulation of digestion and absorption, applicable for evaluating different feed materials and enzymes
✅ Fully automated with digital management, making feed evaluation more efficient than traditional methods
Using real feed as a substrate, SDS III replicates the digestion process of the stomach and intestines with high fidelity, offering a faster and more precise alternative to in vitro and in vivo trials. This provides valuable data for optimizing animal feed formulations.
