Effects of Napier Pak Chong 1 grass ensiling with crude glycerin on fermentation quality and chemical composition

Abstract The quality of silage affects the intake and utilization of ruminants. The use of crude glycerin, a by-product of biodiesel production, has potential as a silage additive to improve fermentation. This study aimed to evaluate the fermentation quality and chemical composition of Napier Pak Chong 1 grass ensiling at 60 days of cutting and chopping into 2-3 cm pieces with crude glycerin (CG) at 0, 10, 20 and 30%, which were assigned into a completely randomized design (CRD) with three repli
