Abstract:

The study was to investigate the effect of Moringa oleifera Lam. extract (MOLE) on the production performance,slaughter performance,meat quality,antioxidant and serum biochemical indexes of AA broilers,and evaluate its availability as a feed additive and its optimal dosage.A total of 480 one-day-old healthy AA male broilers were selected and randomly divided into 5 groups with 6 replicates per group and 16 broilers per replicate which were control group (basal diet),antibiotic group (basal diet+50 mg/kg chlortetracycline) and 3 groups supplemented with MOLE of 0.25,0.50 and 1.00 g/kg in basal diet,respectively.The trial lasted for 42 days composed of two stages (1 to 21 d and 22 to 42 d).The results showed as follows:①Compared with the control group,the final body weight and ADG in antibiotic group were significantly improved (P<0.05),and the final body weight and ADG of 1 to 42 d in 0.25 and 0.50 g/kg MOLE groups were significantly increased (P<0.05) and 0.50 g/kg MOLE had a better effect.There were no significant differences in ADFI or F/G among treatment groups(P>0.05).②There was no significant difference in the slaughter performance and meat quality among all groups (P>0.05).③Compared with the control group,the T-AOC of broilers were significantly increased in antibiotic group and 0.50,1.00 g/kg MOLE groups (P<0.05),and 0.50 g/kg MOLE had a better effect.The serum MDA in MOLE groups were significant decreased compared with antibiotic group (P<0.05).④There was no significant difference in biochemical indices in serum among all groups (P>0.05).⑤0.25,0.50 and 1.00 g/kg MOLE supplementation decreased the death rate of broilers to 1.04%,3.13% and 2.08%.In conclusion,the supplementation of MOLE could improve weight gain and antioxidant capability,and reduce the death rate of the broilers.The optimal supplemental level of MOLE was 0.50 g/kg under the conditions of this experiment.
