Effect of Substitution of Protein form Soybean Meal by Superworm Meal Defatted on Digestibility of Nutrition by Using In Vitro Gas Production Technique

Abstract

This study aimed to investigate the effect of substitution of protein form soybean meal by Superworm meal defatted on nutritional digestibility using In Vitro gas production technique. The experimental design was completely randomized design (CRD) to study the levels of substitution of soybean meal by Superworm meal defatted in concentrate at 0, 33, 67 and 100%. The results showed that Gas kinetics in substitution of soybean meal by Superworm defatted meal un affected (P>0.05) on the intercept value (a), the insoluble fraction (b), rate constant for the insoluble fraction (c), potential extent of gas production (a+b), cumulative gas production at 96 h, and In Vitro organic matter digestibility (IVOMD), while In Vitro dry matter digestibility (IVDMD) of 0, 33 and 67% of substitution was similar. Base on this study it could be concluded that Superworm defatted meal could substitution of soybean meal with un affected on a, b, c, a+b and IVOMD, while IVDMD of 0, 33 and 67% of substitution was similar. Superworm defatted meal could alternative protein source for ruminants. However, further research should be conducted the use of Superworm defatted meal in In vivo trial.
