Influence of dietary organic acid, probiotic and antioxidant on the growth performance and nutrient digestibility in growing rabbit

This study was conducted to compare the effects of different feed additives namely, organic acid (citric acid), probiotic (navio plus), and antioxidant (Bio-Sel-E) on growth performance nutrient digestibility in growing rabbit convey a clear message use one specific additive diet. Thirty-two crossbred New Zealand White (four five weeks age) were randomly assigned four groups reared for period fifty six days. Rabbit fed green grass (Hymenachne pseudointerrupta) concentrate mixture (2703 Kcal ME/kg, 16.91 % CP). Additives added at top mixture, except control group. Compared with group, showed 9–13% higher rate 7–11% greater velocity; supplemented group best result (P<0.05) terms FCR value. Carcass weight (%) increased significantly but numerically compared Abdominal fat decreased acid, control, however, lowest value recorded Probiotic significant effect pH decreasing trend ingesta sample up small intestine. Crude protein co-efficient Overall results indicated that, among three additives: antioxidant, may be considered as better rabbit.
