In a defining moment for Nigerian agricultural science, an innovative study authored by Ajao A. M., a then-rising scholar from the Department of Animal Nutrition at the Federal University of Agriculture, Abeokuta, has captured national attention for its groundbreaking approach to enhancing poultry production using ginger powder as a natural growth enhancer. Co-authored with experts A. O. Oso, A. O. Lala, O. Olowofeso, and A. D. Adeniran, this seminal work offers a compelling, evidence-based alternative to synthetic antibiotics in animal feed, placing Nigeria at the forefront of global conversations on sustainable, health-conscious livestock management.
Published in the Nigerian Journal of Animal Production (Vol. 45, Issue 1), a peer-reviewed outlet of the Nigerian Society for Animal Production, the study meticulously explores the physiological, hematological, and biochemical effects of ginger powder inclusion in the diets of starter turkeys. Using a rigorous experimental framework that spanned 56 days and involved 120 British United Turkey (BUT) poults, the research revealed that moderate inclusion of ginger powder—specifically at 2 grams per kilogram of feed—resulted in statistically significant improvements in final body weight, feed conversion efficiency, and overall health indices, particularly during the crucial starter phase.
Speaking at a departmental colloquium shortly after publication, Ajao noted, “Our motivation was to provide data-driven solutions that address the twin challenges of animal health and feed cost sustainability. Ginger is widely available in Nigeria and offers a phytogenic pathway to improve performance without resorting to antibiotics, which pose long-term health and ecological risks.”
The research comes at a time of heightened urgency in Nigeria’s poultry sector, as farmers and policymakers alike confront the global threat of antimicrobial resistance (AMR) and the spiraling costs associated with imported synthetic feed additives. By leveraging a locally sourced, affordable, and culturally familiar plant—Zingiber officinale (ginger)—Ajao’s work offers a paradigm shift: a sustainable feed formulation model rooted in indigenous resources, scientifically validated for efficacy, and replicable across poultry farming systems nationwide.
The study’s findings are far from anecdotal. The research employed a randomized design, with poults evenly distributed across three treatment groups: a control group (0g ginger), a low-inclusion group (2g/kg), and a high-inclusion group (4g/kg). The researchers tracked a wide range of performance indicators, including body weight, feed intake, feed conversion ratio (FCR), red and white blood cell counts, packed cell volume (PCV), hemoglobin (Hb) levels, serum albumin, hepatic enzymes (AST, ALT, ALP), and mortality rates. The data revealed that the 2g/kg ginger group significantly outperformed the control and high-inclusion groups, with improved feed utilization, higher growth rates, and superior hematological and biochemical health profiles.
Perhaps most notably, the inclusion of ginger was shown to reduce serum markers associated with liver stress while enhancing serum albumin—a key indicator of protein synthesis and metabolic efficiency. This finding is particularly relevant in the context of early-stage poultry development, where immune competence and metabolic health are directly linked to long-term productivity.
The implications of this research ripple far beyond academia. For poultry farmers across Nigeria’s Southwest and Middle Belt—regions with high turkey farming concentrations—Ajao’s findings offer a practical, low-cost method to enhance flock performance while reducing reliance on costly and controversial antibiotics. At a time when the Nigerian poultry industry contributes over ₦1.6 trillion to the economy annually, innovations like this have the potential to boost national productivity, ensure food safety, and empower small- and medium-scale farmers with accessible technologies.
Agricultural extension officers and veterinary professionals have lauded the work. Dr. Grace Udo, a livestock consultant with the Ogun State Ministry of Agriculture, commented, “This is one of the most actionable and timely studies I’ve seen in recent years. The use of ginger aligns with consumer demands for organic and residue-free poultry, and it’s rooted in ingredients already familiar to Nigerian communities.”
The study also gained academic traction, being cited in postgraduate theses and incorporated into curriculum discussions within animal nutrition and veterinary physiology courses. Scholars from the University of Ilorin, Ahmadu Bello University, and Obafemi Awolowo University have referenced Ajao’s research in their own inquiries into phytogenic feed additives and non-antibiotic growth promoters. This national academic recognition underscores the work’s relevance, scientific rigor, and replicability.
Equally important is the study’s contribution to Nigeria’s obligations under the Global Action Plan on Antimicrobial Resistance, coordinated by the World Health Organization (WHO). Nigeria is among several African nations working to reduce the use of medically important antibiotics in livestock. By proposing ginger—a natural, abundant, and cost-effective alternative—Ajao’s research provides a practical route for achieving these health policy goals without compromising productivity.
Furthermore, Ajao’s team ensured statistical precision and scientific transparency. All data were subjected to one-way analysis of variance using SAS (1999) and orthogonal contrast analysis through SPSS, confirming both linear and quadratic trends in ginger dosage responses. The methodology conformed with international animal welfare standards, and blood sample analyses employed industry-approved protocols using EDTA and serum-separating tubes for accuracy.
It is also worth noting the innovation embedded in the study’s processing of ginger itself. Fresh rhizomes were carefully washed, sun-dried, and ground to a 1mm particle size for uniform dietary blending. The attention to preparation highlights an often-overlooked area of feed formulation: ingredient handling and standardization, which are essential for reproducibility and scale-up.
As Nigeria looks to build local capacity in agricultural technology and reduce its reliance on imports, studies like this are invaluable. They reflect not just the intellectual capital of the country’s tertiary institutions, but the power of context-aware, resource-efficient, and economically scalable scientific innovation. Ajao’s work bridges the often-fragmented divide between traditional knowledge and contemporary science, translating the health benefits of ginger—long revered in West African ethnomedicine—into quantifiable improvements in poultry health and farm economics.
At a broader level, this research aligns with continental goals articulated in Agenda 2063, the African Union’s blueprint for inclusive and sustainable development. By leveraging indigenous botanicals and prioritizing scientific validation, Ajao’s model advances agricultural productivity, promotes food sovereignty, and reduces environmental toxicity associated with synthetic additives.
At the time of publication, Ajao was still an early-career scholar, yet the maturity and technical depth of the work speak to a talent whose contributions already exceed academic expectations. His ability to lead a complex, multidisciplinary research initiative—spanning animal physiology, microbiology, biochemistry, and statistics—signals a trajectory of impact, innovation, and leadership in Nigerian agricultural science.
In interviews following the publication, colleagues described Ajao as a “committed researcher with an instinct for solving real-world problems.” Professor A.O. Oso, one of his co-authors and a mentor on the project, remarked, “What impressed us most was his ability to ask the right questions and follow them up with structured, data-informed experiments. His curiosity is matched only by his dedication to scientific excellence.”
Since its publication, the study has been circulated among feed millers, livestock cooperatives, and policy advisors seeking to implement safer and more sustainable production strategies. The demand for antibiotic-free poultry is growing—not only among health-conscious Nigerian consumers but also in international markets where residue monitoring is stringent. Ajao’s findings position Nigeria to compete globally in the export of poultry and poultry products, provided the models are adopted at scale.
As a new generation of agricultural scientists rises to meet the challenges of food insecurity, climate change, and rural poverty, Ajao A. M. stands out as a voice of relevance, rigor, and responsibility. His work exemplifies the core values of research that is not just publishable—but profoundly actionable.
This publication in The Nigerian Journal of Animal Production, now spotlighted across the national media, has become a touchstone for emerging discourse on natural feed additives. It has shown that science rooted in local knowledge can deliver solutions that are global in impact, practical in design, and equitable in benefit.
With future research reportedly underway to test ginger-based feed formulations in broilers and layer hens, it is clear that this is only the beginning of a much larger conversation—one that places Nigeria not at the periphery, but at the center of global innovation in sustainable animal agriculture.
