Effects of Quercetin, vitamin E, and Q + VE supplementation on the immune organ weight and index of the aging hens.

Parameters	Control	Quercetin	Vitamin E	Q + VE
Spleen weight (g)	2.56 ± 0.77^b	4.62 ± 1.39^a	4.81 ± 1.42^a	4. 45 ± 1.70^a
Immune organ index¹	0.11 ± 0.03^b	0.17 ± 0.05^a	0.17 ± 0.07^a	0.21 ± 0.08^a

The values are presented as mean ± standard deviation.

^a,b

Means in the same row without a common superscript letter differed statistically (P < 0.05).

Immune organ index (Splenic index) = Organ weight/body weight.
