Popis:	Maize stover constitutes major waste in most farms in Nigeria. Maize stover can be converted to feed for ruminants when fortified with urea. Ammonium nitrogen is lost post feeding without a binder. This study investigated the possibility of using saponin from Aloe vera, an ornamental, as a binder to override this constraint. Three experimental silages were prepared each from 3.6 g kg-1 urea ammoniated maize stover with 135 mg Aloe vera crude saponin extract CSE, synthetic saponin and control. Three rams were randomly allotted to each dietary treatment. Every week a new ram was allotted a treatment for 12 h one day a week for three weeks, each week represented a replicate. Data were collected at 0, 4, 8 and 12 h of feeding. Chemical composition of silages, rumen pH, ammonium nitrogen and volatile fatty acids (VFAs) were determined. The data were analysed as a 3×4 factorial in CRD. Lignin content of silages was reduced when saponin was included in silages. The pH (6.73-7.2) was significantly different (P
