Poultry is the world’s most-consumed meat, and producers face constant pressure to cut costs and reduce reliance on antibiotic growth promoters, increasingly restricted over antimicrobial-resistance concerns. That drives a search for natural feed additives that keep birds healthy and growing without drugs — and Moringa oleifera leaf powder, rich in protein, vitamins and antioxidants, is a leading candidate.
This study, published in Animal Nutrition and Feed Technology by scientists at India’s Central Avian Research Institute, ran a controlled feeding trial to test whether moringa leaf could take on some of that role — without hurting the metric every producer watches: growth rate.
What the study did
420 day-old broiler chicks were divided across six diets and raised for 42 days: a standard corn–soybean control, an antibiotic-growth-promoter diet, and four diets with moringa leaf powder at 0.5%, 1.0%, 1.5% and 2.0%. The team measured growth, blood biochemistry, gut microflora and meat quality.
Key findings
- Body-weight gain, feed intake and feed-conversion ratio showed no significant difference from the control — moringa did not slow the birds down.
- Moringa favourably influenced serum biochemistry and gut microflora.
- It improved the oxidative stability of the meat (lower TBA values) — a real shelf-life advantage.
The takeaway: moringa leaf works in broiler feed at up to 2% as a natural additive that maintains growth while improving gut health and meat keeping-quality — a credible step toward antibiotic-free production.
Caveat: results apply to broilers at the rates tested; optimal levels vary by species and ration. Growth effects were neutral here — gains were in gut health and meat quality.
