BioResource International, Inc. and Academic Research Partners Release New Study on Impact of Xylamax® Xylanase Enzyme in The Journal of Applied Poultry Research

Research Triangle Park, N.C. — September 15, 2016 —BioResource International, Inc. (BRI), a global biotechnology company specializing in the research, development and manufacture of high-performance enzyme feed additives for optimizing animal nutrition and gut health, announced today the release of the research findings on the impact of its thermotolerant xylanase enzyme, Xylamax®, on broiler performance and ileal digestible energy (IDE). The study, published in The Journal of Applied Poultry Research (JAPR), was sponsored by BRI and conducted in collaboration with researchers from Texas A&M University’s Department of Poultry Science, including Dr. Jason Lee, Ph.D., and graduate student Cody Flores.                          

In the first experiment, all birds were fed pelleted corn-soy-DDGS basal diets formulated at a reduced metabolizable energy (ME) level. The control was supplemented with one of two concentrations of Xylamax (20,000 XU/kg diet [XYL20] and 40,000 XU/kg diet [XYL40]). The study demonstrated that at day 42, feed conversion ratio in birds fed XYL20 had improved (P<0.01) compared to the non-supplemented control, and that IDE had increased significantly (P<0.05) at both XYL20 and XYL40 concentrations. In the second experiment, birds were fed pelleted corn-soy-DDGS diets, each containing phytase. Positive control diets were formulated at standard energy levels and ME was reduced in negative control diets by 150 kcal/kg diet. Xylamax was added to the two negative control diets at two different concentrations (XYL10 and XYL20) and broiler performance was evaluated. The results showed a significant increase (p<0.05) in cumulative body weight gain through 42 days with the XYL20 inclusion, compared to the negative control. Based on the two experiments, inclusion of BRI’s Xylamax enzyme increased energy utilization through improvements in IDE and improved overall broiler performance.

“We are extremely pleased to see continued positive results in animal trials using our Xylamax product, and we appreciate the constructive collaboration with our research partners at Texas A&M,” said Dr. JJ Wang, Ph.D., chief technology officer of BRI. “BRI is committed to the design, development and manufacture of high-performance feed additive solutions that are grounded in rigorous scientific research methodology.”

The full report of the two studies, “Evaluation of a thermotolerant xylanase on broiler growth performance and dietary ileal digestible energy value,” can be found on JAPR’s website.
