Effect of Dietary Carboxymethyl Cellulose Level in Diets with different Levels of Protein and Carbohydrates on Digestibility, Growth, and Survival Rate of Tiger Shrimp (Penaeus monodon Fab.)

The purposes of this study were to evaluate the effect of carboxymethyl cellulose (CMC) in feed with different protein and carbohydrate content on protein and carbohydrate digestibility, growth, and survival rate of tiger shrimps (Penaeus monodon). A factorial pattern with a completely randomized basic design and two factors were used. The first was the difference in CMC in the feed, namely 0%, 5% and 10%, while the second was the different protein-carbohydrate levels, namely P 30% - C 40% and P 40% - C 30%. The results showed that the treatments produced similar responses in survival rates of tiger shrimps. The interaction between differences in protein-carbohydrate and CMC content in the feed had a significant effect with p<0.05 on protein and carbohydrate digestibility as well as the biomass growth. Protein and carbohydrate digestibility and absolute growth of biomass at treatment P 40% - C 30% - CMC 0% was the lowest and significantly different from other treatments. Based on protein and carbohydrate digestibility, growth, and survival rates, the feed containing 30% protein, 40% carbohydrates and 5% CMC was the most suitable for tiger shrimps production.
