Assessment of nutritional qualities for ensiled fresh maize stover with different proportion of cassava foliage for sustainable ruminant production was studied. Fresh maize stover (FMT) and fresh cassava foliage (FCF) were collected, wilted for 3 – 4 days, chopped and ensiled in different proportions to make six (6) experimental treatments (T1= 100% FMT; T2= 90% FMT + 10% FCF; T3= 80% FMT + 20% FCF; T4=70% FMT + 30% FCT; T5= 60% FMT + 40% FCF; T6= 50% FMT + 50% FCF). Twenty five (25) liters containers were used as silos with four replicates in completely randomize design (CRD) and ensiled for 30 days. Physical parameters, proximate composition, fibre fractions, mineral contents, anti-nutritional factors and post in-vitro characteristics were monitored. The results showed that pleasant aroma, smooth texture and none moldiness were observed across the experimental treatments. There were significant (P<0.05) differences in the crude protein (CP), crude fibre (CF), ash, non fibre carbohydrate (NFC), neural detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL) and cellulose. Similar (P>0.05) contents of hemicellulose were recorded across the experimental treatments. The anti-nutritional factors varied significantly (P<0.05) from 0.42 – 0.46 %, 0.35 – 0.39 %, 0.47 – 0.50 %, 0.02 – 0.05%, 2.63 – 3.09 and 12.90 – 15.23, for phytate, oxalate, saponin, tannin, trypsin inhibitor and hydrocyanide, respectively. Significant (P<0.05) differences in the mineral contents and post in vitro characteristics were also observed across the experimental treatments. Conclusively, T4 (30%), T5 (40%) and T6 (50%) inclusion levels of FCF give better results. It’s therefore recommended that FCF up to 50% inclusion levels can be ensiled with maize stover for sustainable ruminant production.
