What 22,451 Publications Reveal About Global Poultry Research
When the journal Poultry Science published its first issue in 1921, the world of chicken farming looked dramatically different. Backyard flocks and small operations dominated, with little understanding of nutrition, genetics, or disease prevention that would transform the industry. Today, poultry stands as the most consumed meat globally, accounting for approximately 30% of global meat consumption 1 .
Advanced breeding techniques
Optimized feed formulations
Disease prevention and control
This remarkable transformation didn't happen by accident—it emerged from a century of scientific research spanning genetics, nutrition, health, and management practices. But how does one begin to map and understand this vast scientific landscape?
The science of measuring and analyzing scholarly literature. By applying statistical techniques to thousands of publications, researchers can trace the evolution of ideas, identify emerging trends, and map global collaborations.
A recent groundbreaking analysis of 22,451 articles from Poultry Science's 100-year history reveals fascinating patterns in how poultry research has evolved 2 . This isn't just academic curiosity—understanding these research trends helps shape future innovations that will make poultry production more efficient, sustainable, and ethical.
Scientometrics might sound like jargon, but its concept is straightforward: it's essentially GPS for scientific knowledge. Just as mapping software helps us visualize terrain and navigation patterns, scientometric tools create visual maps of research landscapes.
Researchers employ sophisticated software to analyze publication data, citation networks, author affiliations, and keyword frequencies across decades of scholarly work.
The analytical process involves both quantitative metrics (counting publications and citations) and qualitative assessment (categorizing research topics and tracing conceptual evolution).
Which countries lead in poultry research?
How have research priorities shifted over time?
Which topics are gaining momentum?
When 22,451 articles from a 100-year period are fed into these analytical tools, patterns emerge that would be impossible to detect through casual reading 2 . The answers provide valuable insights for researchers, policymakers, and industry leaders aiming to allocate resources effectively and address emerging challenges.
When we examine the geographic distribution of poultry research, clear patterns of leadership and collaboration emerge. The United States has historically dominated the field, contributing 9,421 articles (43.16%) of the total publications analyzed 2 . However, the global landscape has become increasingly multipolar over time.

Different countries often specialize in different aspects of poultry research. While the U.S. has maintained strength across multiple domains, other nations have developed particular expertise—whether in genetics, nutrition, or disease management.
This specialization creates mutual benefits through international partnerships and reflects varying national priorities, resources, and historical strengths.
The most fascinating insights from scientometric analysis come from tracing how research priorities have shifted over the century. When we examine the subject areas across different time periods, we see a dramatic story of scientific evolution.
| Time Period | Most Researched Area | Percentage of Articles |
|---|---|---|
| 1921-2020 | Nutrition and Metabolism | 14,109 articles |
| 2011-2020 | Molecular Biology | 1,420 of 2,466 articles (57.58%) |
For most of the journal's history, "nutrition and metabolism" dominated poultry research, reflecting the industry's focus on optimizing growth and production efficiency 2 .
Feed constitutes the largest cost in poultry production, making nutritional research economically crucial.
The most striking shift occurred in the last decade, with molecular biology surging to the forefront 2 . This mirrors trends across biological sciences, where genomic tools have revolutionized everything from breeding to disease management.
The relatively recent interest in modeling reflects the industry's increasing sophistication in using computational approaches to predict outcomes and optimize complex systems.

To understand how modern poultry research integrates advanced technologies, let's examine a cutting-edge experiment detailed in a 2025 issue of Animals journal. The study addressed one of the most labor-intensive tasks in large-scale poultry farming: accurately counting chickens in densely packed cages 3 .
The research team developed YOLO-CCA (You Only Look Once-Chicken Counting Algorithm), an enhanced deep learning model based on YOLOv8 architecture.
This technological advancement represents more than just convenience. The research exemplifies how computer vision and artificial intelligence are transforming traditional farming practices into precision livestock farming.
Modern poultry research relies on a diverse array of tools and reagents that enable scientists to tackle questions from the molecular to the farm-level scale.
| Tool/Reagent | Function/Application | Example in Research |
|---|---|---|
| PEGylated Proteins | Improve pharmacokinetics of therapeutic proteins | PEG-chPRL showed prolonged circulation (16+ hours) in chickens 4 |
| Real-time PCR | Detect and quantify pathogens and resistance genes | Identification of vancomycin-resistant enterococci in turkey flocks 5 |
| Deep Learning Models | Automated monitoring and counting of birds | YOLO-CCA for accurate chicken counting in cages 3 |
| Statistical Power Analysis | Determine optimal sample sizes for ethical research | Nested ANOVA for estimating bird-to-bird and pen-to-pen variation 6 |
| Antimicrobial Susceptibility Testing | Profile resistance patterns in bacterial isolates | Identification of multidrug-tolerant Enterococcus strains from poultry 5 |
The diversity of these tools reflects the increasingly interdisciplinary nature of poultry science, where molecular biology, computer science, ethics, and traditional animal husbandry converge to advance the field.
The scientometric analysis of poultry research reveals a field in dynamic transition. From its origins in basic nutrition and management, poultry science has evolved to embrace molecular biology, computational approaches, and high-tech monitoring systems. The global research landscape continues to expand beyond traditional centers of excellence to include growing contributions from developing countries where poultry production represents a crucial protein source.
Integration will expand beyond counting chickens to monitoring health, predicting disease outbreaks, and optimizing environmental conditions.
Continued advancement potentially leading to breakthroughs in disease resistance and nutrient utilization through gene editing.
Considering animal welfare, environmental sustainability, and production efficiency as interconnected goals.
As one review article aptly noted, future challenges for the poultry industry will require considering not just disease control but "the interconnection of the animals' health, welfare, and immunity" along with "economic, ethical, social dimensions, and the sustenance of the accomplishment of high environmental security" 5 .
The scientometric mapping of poultry research provides both a mirror reflecting our past progress and a compass pointing toward future innovation—ensuring that the science behind our poultry production continues to evolve in response to both human needs and animal welfare.
