Abstract
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 (6weeks) 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 (0.92mmol/L) compared to the other treatments. The superoxide dismutase (SOD), phosphorous (P) and magnesium (Mg) increased (p<.05) in T1 (658.01nmol/ml, 5.1mg/kg and 2.43mg/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.
