Abstract
Results obtained can be summarized as follows:
a-The phase of breeding and production of Tenebrio molitor larvae (TML) Insect of TM were reared on three different substrates (turkey litter, laying hens litter and broiler litter) to determine the best substrate for production, growth and nutritional value of the larvae. Larvae from Turkey litter were the best in its content of protein (52.8 %) and lipid (31.78 %)
b – Feeding experiment 1:
1. For the entire experiment period, ducklings fed TML and Yeast supplemented-diets had significantly (P≤0.05) greater body weight, body weight gain and better feed conversion ratio than that of the control group during period (0-28 d).
2. TML supplementation (0.5%) had no significant differences in dressing percentage with control, but gizzard, and intestine significantly increased with TML in the first slaughter at 21 d. Meanwhile liver, heart, pancreas and fabricius were not significantly affected by the supplementation of TML.
3. Spleen, thymus and caecum were significantly (P≤0.05) increased in group fed diet supplemented with yeast 0.3%
4. Dressing percentage at 45 d was significantly improved of ducklings fed diet supplemented with TML (0.5%) compared to the control group. Meanwhile heart, Pancreas and spleen were not significantly affected by the supplementation of TML.
5. Liver, Thymus, Fabricius, Intestine and Caecum were significantly lower of groups fed TML (0.5%).
6. TML supplementation at 0.5% significantly increased triglyceride and IGM. Meanwhile TML supplementation didn’t have significant effect on Albumin. Cholesterol and Glucose at 21 days of age.
7. Total protein, Albumin, Triglyceride were not significantly influenced by TML supplementation. At 45 days of age.
8. No significant effect on WBCS and IGG with MWL supplementation at 45 days of age
9. Cholesterol was significantly increased (P≤0.05) with TML supplementation 0.5% at 45 days of age .
10. Villus height at 21 days of age was significantly improved in Yeast and TML groups compared with control.
11. TML supplementation at 0.5% significantly increased crypt depth at 21 day of age compared with control and yeast groups while at 45 days of age yeast groups was significantly higher in crypt depth compared with TML supplementation.
12. Villus height to crypt depth was significantly higher in TML 0.5% and yeast 0.3% during the period 21 but at 45 days of age only yeast .3% had the highest % of all
13. No significant effect on the viable count of E-coli ,Salmonella, Lactobacillus and Enterobacter in gastrointestinal content. While there is a significant (P≤0.05) in the contents of total bacterial count in the gastrointestinal in the different group at 21 days of age.
14. E-coli were significantly lower in TML and yeast groups compared with control at 45day of age.
