The effect of the chelated form of trace elements in diet on weight gain, production traits, egg specific gravity, immune system, blood parameters, liver enzymes, and progesterone hormone in Ross 308 broiler breeder chickens

This experiment was conducted in order to investigate the effect of chelated form trace elements diet on production traits, immunity, and blood parameters Ross 308 broiler breeder chickens. Treatments included Treatment 1 (Negative control): Mn, Se, Cu, Fe Zn provided as non-chelated form; 2 (Positive 3: 50% 4: 5: Cu 6: 7: Mn 8: Se form. The results showed that over entire period egg mass were affected by experimental treatments (p < 0.05) highest levels observed 3. had a significant effect, increasing number settable eggs decreasing unsettable 0.05). Average weight not significantly changed > percentage 2-yolk, thin shell, broken small 61st week age immunity antibody titre against Newcastle disease increase 8 concentration glucose, triglyceride, progesterone, AST ALT In conclusion, use basic containing Zn, Fe, or mineral with improves performance chickens.HighlightsChelated led improvement productive immune response compared formBasic production, mass, specific gravityChelated decrease abnormal including double-yolk, broken, deformed,
