Table 1. Estimated chemical composition (%, dry matter basis or as stated) of experimental feeds used for in vivo

Item	Composition
	Concentrate	Forage
DM (%, as fed basis)	89.8	87.8
CP (%)	17.5	6.00
NDF (%)	37.1	61.1
ADF (%)	17.8	40.0
Lignin (%)	3.76	5.59
EE (%)	4.07	1.85
Ash (%)	9.25	6.85
Ca (%)	1.28	0.16
P (%)	0.76	0.19
NFC (%)	32.08	24.2
TDN1)(%)	68.2	57.3

The value of TDN was calculated by the methods suggested from NASEM (2016).
DM, dry matter; CP, crude protein; NDF, neutral detergent fiber analyzed with heat stable α-amylase; ADF, acid detergent fiber; EE, ether extract; NFC, non-fibrous carbohydrate; TDN, total digestible nutrients.
