Research—Silica+ Improves Protein Utilization


A study, conducted at the Prince of Songkla University in Thailand and supervised by Dr. Wutiporn Phromkunthong, showed that in diets for Penaeus vannamei, “Silica+” (at an inclusion rate as low as 200 parts per million) could lower the requirement for fish meal from 15% to 7.5%.  A significant difference was observed between the experiment and control groups in terms of average body weight.  The weight gain in the experimental group was 12.5% higher than that in the control group and the feed conversion ratio was significantly lower.  A second study conducted with P. vannamei at the Guangdong Ocean University research facility in Guangdong Province, China, confirmed that “Silica+” helped reduce the quantity of fish meal from 25% to 15%, while maintaining the same growth in shrimp.
