Organic matter (OM), neutral detergent fibre (NDF) digestibilities and metabolizableenergy content of some available agro-chemicals wastes (AIW) such as dry brewer's grain cocoa shell, cocoa dust, dessicated cocnut waste meal, wheat bran and rice bran used as ruminant feeds were setimated from in vitro gas production technique. Their crude protein (CP) content varieted from 13.7-25.6%, NDF ranged from 21.9-48.4% Om from 88.6-95.4% and non structural carbohydrates (NSC) estimates increased from 7.2 - 45.6%. Dessicated coconut waste meal(DCWM) had the lowest NSC content. Nutrient contents varied among AIW. Net gas production ranged from 7.7-23.1 ml/day and significant differences (P<0.05) were observed among the AIW in net gas production. The lowest and highest gas productions were obtained in cocoa dust (CD) and wheat bran (WB) respectively. Om digestibility  also had higher ME values showed significantly the differences between the AIW. AIW with high OM digestibility also had higher ME values. Finally the investigation demonstrated that available AIW in the pacific Island countries have potential as animal feedstuffs
