Table 5. Effect of treatments on the total bile acid concentrations (TBAC)and ileal nutrient digestibility coefficients on day 41.

Observation	Treatment					SEM	P-value
	T1	T2	T3	T4	T5
TBAC (mmol/L)2	29.1b	26.6b	40.6a	43.3a	43.8a	1.583	0.001
Ileal digestibility coefficients2, 3 (DM4)
Crude protein	0.75	0.78	0.74	0.79	0.75	0.007	0.193
Ether extract	0.78	0.79	0.79	0.79	0.79	0.008	0.987

¹Treatments: T1 control, T2 avilamycin, T3 crude ethanol extract (CEE) of Jakr-Na-Rai (JNR) granules (0.13% flavonoid), T4 JNR powder (0.13% flavonoid), and T5 JNR powder (0.26% flavonoid).

²Mean value from six replications per treatment on day 41.

³Pooled ileal content samples from two birds per replication on day 41.

^a-bMeans in the same row with different superscript letters are significantly different (P<0.05).

⁴DM=dry matter.
