Two hundred White Leg Horn Layers (70 week age) were arranged and brought to the poultry research station, Department of Physiology and Pharmacology, University of Agriculture, Faisalabad. Four groups were made (n=50 each) into keeping G1 as control (CP 16%, No other supplement), G2 (CP 18% diet), G3 (CP16% diet; symbiotic @ 85 mg L-1/day) and G4 (CP 16% diet; probiotic @ 85 mg L-1/day). The body and organs (heart, liver, spleen, kidney, brain and pituitary) weight from fifteen birds in each group at 5% (5P), peak (PP) and end (EP) of post molt production stage were determined. The overall mean heart weight in G2 and pituitary weight in G2 and G3 reduced (P less than or equal to 0.05) as compared to G1. The mean kidney weight found increased (P less than or equal to 0.05) in G3 and G4 as compared to G1. The results show metabolic relation of protein and probiotics with body organs.
