Contained 87.61% of glycerin, 8.07% of water, 1.24% of sodium, and 0.64% of methanol (Colorless, odorless, viscous liquid obtained from Biodiesel Producers, New Biodiesel, Surat Thani Province, Thailand.).
Minerals and vitamins (each kg contains): Vitamin A 10,000,000 IU; Vitamin E 70,000 IU; Vitamin D 1,600,000 IU; Fe 50 g; Zn 40 g; Mn 40 g; Co 0.1 g; Cu 10 g; Se 0.1 g; I 0.5 g.
Based on analysis of composite feed sample.
DM = Dry matter; OM = Organic matter; CP = Crude protein; EE = Ether extract; NSC = Non-structural carbohydrate; NDF = Neutral detergent fiber; ADF = Acid detergent fiber; ADL = Acid detergent lignin.
Calculated with an estimated ME for glycerol of 3.47 Mcal/kg of DM (Mach et al., 2009).
