Summary This study examined the effects of Lactobacillus plantarum and Pediococcus acidilactici‐ treated silage of King grass ( Pennisetum purpureophoides ) on the productive traits and blood biochemistry of New Zealand white ( NZW ) rabbits. King grass was ensiled without or with L. plantarum (T1), P. acidilactici (T2) and P. acidilactici + L. plantarum (T3). A total of 72 male NZW rabbits (6 weeks) of similar weight and appearance were housed in groups in metallic cages in a completely randomized design. The performance traits, daily feed intake, body weight gain and feed convention ratio were not affected by the silage treatment. Triglyceride and alanine aminotransferase ( ALT ) concentration was increased ( p < .05) in T2 (0.92 mmol/L) compared to the other treatments. The superoxide dismutase ( SOD ), phosphorous (P) and magnesium (Mg) increased ( p < .05) in T1 (658.01 nmol/ml, 5.1 mg/kg and 2.43 mg/kg, respectively) compared to the control and other experimental groups. Cu and Mn decreased ( p < .05), while Zn increased ( p < .05) in the treated groups compared to the control. The CP decreased ( p < .05) in the treatment groups compared to the control. Neutral detergent fibre ( NDF ) increased ( p < .05) in T2 (54.40%) compared to the other treatments. The inoculation of lactic acid bacteria‐treated King grass silage supplementation positively affected rabbit performance and improved blood cholesterol profile, antioxidant status and improve nutrients digestibility.
