Abstract
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≤0.05) as compared to G1. The mean kidney weight found increased (P≤0.05) in
G3 and G4 as compared to G1. The results show metabolic relation of protein and
probiotics with body organs.
