Simulated Digestion System (SDS III) for Monogastric Animals

How to evaluate the nutritive value of feed ingredients accurately, efficiently and repeatably?

How to evaluate the enzymolysis efficacy of different single enzymes on various feed materials?

How to evaluate the compound enzyme preparations from the markets efficiently and screen the most suitable compositions of enzyme products?

Animal experimentation need a long cycle and high cost, and the experimental data are susceptible to many uncertain factors such as climatic conditions, animal body conditions, and feeding conditions. How to solve these problems?

Simulated digestion system (SDS III) for monogastric animals has been jointly developed by Institute of Animal Science, Chinese Academy of Agricultural Sciences (IASCAAS) and Hunan Zhongben Intelligent Technology Development Co., LTD. It is a patented technical solution to automatically simulate the digestive system of monogastric animals, based on bionic principles. SDS III includes a device that can simulate the digestion and absorption process of feed in the digestive tract, and the matching kit of simulated digestive solution. SDS III uses feed as a substrate to simulate the digestion and absorption process of in vivo gastro-intestinal tract with high fidelity and repetition. Compared with the in vitro, in situ and in vivo methods, SDS III can accurately and efficiently determine the effective energy value, digestibility of amino acid and phosphorus in feed, and realize the standardization, datafication and automation of the simulated digestion method.

As the global strategic cooperation partner, UniVOOK is authorized to take fully responsibility of markets promotion and sales business for the SDS III system and reagents worldwide.

1- Feed Energy Value Evaluation;

The evaluation of nutritive values of feed ingredients is the critical scientific decision basis for feed ingredient price assessment and feed formula optimization. The SDS III system can efficiently identify the nutritive values of feed ingredients, complete diets, and screen enzyme combinations suitable for different feed ingredients, thereby improving feed utilization and reducing cost.
