ABSTRACT
This study carried out in two experiments. The first was a laboratory experiment to study the effect of nano-peptides made from methionine, tryptophan and iron on the growth of E. coli and Salmonella cultured from chicken intestines (concentrations of 50, 100 and 150 μL/plate). The results showed a positive effect of the manufactured nano-peptides (NPe) on both types of bacteria. There was significant increase in the diameter of decrease for concentrations of 100 and 150 microliters compared to concentration 50. The second experiment was conducted in the field, using 360 broiler (Ross 308), divided into six treatments (C1: Control treatment, C2: Control treatment with 0.5% H2O2, and C3, C4, C5, C6 adding 1,2,3,4 ml of synthetic peptides with 0.5% H2O2), Significant increase in live body weight and weight gain for treatments C4 and C6. All supplementation treatments improved in the feed conversion ratio compared with the control treatments. Packed cell volume (PCV) and hemoglobin (Hb) levels increased in treatment C5. Improvement in treatments C4, C5 and C6 appeared in the percentage of lymphocytes and heterophil. All supplementation treatments improved in the H/L ratio compared with the control treatment C2.
