ABSTRACT
Moringa oleifera leaf (MOL) has been used in traditional medicine for its multiple bioactive components beneficial to animals and humans. However, the effects of Moringa oleifera leaf extract (MOLE) supplementation on growth performance and intestinal morphology in weaned pigs are poorly understood. This study examined the effects of MOLE supplementation (250 mg/kg or 500 mg/kg diet) on 144 Duroc × Landrace × Large White weaned pigs over a 5-week period. The results of this study showed that dietary supplementation with MOLE for 5 weeks improved average daily weight gain, feed efficiency and reduced the incidence of diarrhea in weaned pigs. Blood hematological parameters, intestinal morphology, and fecal microbial shedding were assessed at the end of the experiment. MOLE supplementation did not significantly affect blood indices, except for a reduction in neutrophils and an increase in MCHC at 500 mg/kg diet (P=0.025 and 0.042, respectively). Villus height/crypt depth in the 250 mg/kg diet MOLE group was significantly higher than in the control group (P=0.002). Our study is the first to report that dietary supplementation with MOLE granules at 250 mg/kg improved growth performance, reduced diarrhea rate, and microbial shedding in weaned pigs.
