Sustainable livestock production requires innovative feeding strategies that enhance forage quality while utilizing locally available agricultural resources efficiently. This study evaluated the influence of graded inclusion levels of air-dried layer droppings on the nutritional, fibre and mineral characteristics of Brachiaria ruziziensis silage. The experiment was arranged as a 3 × 4 factorial in a Completely Randomised Design (CRD), comprising three inclusion levels of air-dried layer droppings (0%, 5%, and 10% on a dry matter basis) and four ensiling durations (0, 21, 42, and 63 days), replicated three times. Proximate composition (dry matter, crude protein, ash, ether extract, crude fibre), fibre fractions [neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL)], in vitro organic matter digestibility, and mineral content (macro and micro) were determined using standard methods. Significant (P?<?0.05) interaction effects of inclusion level and ensiling duration were observed for all proximate, fibre, and mineral parameters evaluated. The highest crude protein (7.73%) was recorded at 10% inclusion level after 42 days of ensiling, compared to 5.53% in the un-ensiled control. In vitro organic matter digestibility peaked at 51.02% at 5% inclusion after 21 days of ensiling. Neutral detergent fibre ranged from (66.65 - 70.04%), with acid detergent lignin increasing progressively with ensiling duration, peaking at 4.64% at 5% inclusion after 63 days. Mineral concentrations were significantly enhanced by inclusion of layer droppings; phosphorus peaked at 2.99 g/kg (10% inclusion, 42 days), calcium at 2.77 g/kg (5% inclusion, 21 days), and magnesium at 3.06 g/kg (5% inclusion, 21 days). Findings indicate that ensiling B. ruziziensis with 5–10% air-dried layer droppings for 21–42 days optimises crude protein content, digestibility, and macro-mineral enrichment, supporting its use as a high-quality supplement for ruminant feeding in tropical production systems.
