Abstract :

The present investigation was carried out to evaluate the effects of dioxide titanium particles on growth and performance character. Based on previous works, it is expected that TiO2 nanoparticles (NPs) improving the feed efficiency and promote silk protein synthesis in the silkworm can be improved important traits such as cocoon shell weight and cocoon weight. The experiment was designed in a completely randomized design with three replications. Five groups of silkworms fed diets with dioxide titanium nanoparticles at 0, 5, 10, 50, and 100 mg/l in duration 4 and 5 instars. Data were analyzed by SAS software, and Duncan test was used to compare the mean. It was observed that the addition of dioxide titanium nanoparticles at different levels significantly improved percent viability, cocoon and cocoon shell performance compared control group.  In comparison to the control treatment, cocoon weights rose by 3.3 and 3.85 percent in 5 and 10 mg/l dioxide titanium, respectively. In comparison to the control treatment, 5 mg/l nanoparticles had a higher cocoon shell weight and cocoon shell ratio of 10.40 and 6.27 percent, respectively. Results showed that using dioxide titanium nanoparticles in 5 and 10 mg/l can increase cocoon and cocoon shell performance, but it has not effect on these traits with higher concentration.
