Exploring the socio-economic importance and phenotypic characteristics of an indigenous poultry breed sustaining tribal communities
In the lush, tribal-dominated districts of Northern Odisha, a native chicken known for its resilience and distinct characteristics plays a crucial role in the socio-economic fabric of rural communities. The Khadia chicken, though not officially registered as a standardized breed, represents a valuable animal genetic resource that has evolved through generations of natural and selective adaptation to local conditions 1 3 .
These birds are not merely livestock but represent an integral component of food security and livelihood sustainability for tribal households, particularly those with limited land resources 3 .
As India witnesses rapid expansion in commercial poultry production, understanding and preserving unique indigenous poultry varieties like the Khadia becomes essential for maintaining genetic diversity and supporting sustainable agricultural systems 1 .
This article explores the fascinating intersection of traditional farming practices, genetic conservation, and rural economics through the lens of Khadia chicken rearing in Odisha. We will examine the distinctive phenotypic characteristics of these birds, their production performance, and how they contribute to the economic resilience of tribal communities.
The rearing of indigenous chicken forms a critical economic safety net for rural households across India, particularly for tribal communities with limited agricultural land and economic opportunities. Research conducted in Northern Odisha reveals that approximately 72.5% of Khadia poultry rearers earn an average of ₹20,000 annually from their small-scale farming operations 2 3 6 .

| Flock Size Surveyed | 1,435 Khadia chickens | Comprehensive phenotypic characterization |
Beyond direct economic benefits, Khadia chickens play a vital role in household nutrition through egg production and occasional meat consumption. The low-input, free-range nature of this farming system makes it particularly suitable for resource-constrained families who can leverage common property resources and kitchen waste for feeding their flocks 1 3 .
The Khadia chicken exhibits a range of distinct phenotypic traits that differentiate it from other registered native breeds of Odisha, such as the Hansli. These characteristics have developed over generations through natural selection in the specific agro-climatic conditions of Northern Odisha, combined with selective breeding by tribal communities for desired traits.
| Trait | Performance Metric | Comparative Advantage |
|---|---|---|
| Annual Egg Production | 70.7 ± 1.26 eggs | Sufficient for household consumption and sale |
| Fertility Rate | 80.41 ± 1.38% | High natural reproduction capability |
| Adult Male Weight | 1,839.5 ± 22.274 g | Good meat yield for family nutrition |
| Adult Female Weight | 1,388.75 ± 10.96 g | Optimal size for backyard management |
| Shank Length (Male) | 1.12 ± 0.22 cm | Distinctive physical characteristic |
The morphological measurements of Khadia chickens further confirm their distinct identity among indigenous poultry populations. Studies recorded a shank length of 1.12 ± 0.22 cm in males and 9.78 ± 0.24 cm in females, along with specific keel length measurements that differentiate them from other native breeds 6 .
The study of Khadia chicken takes place against a concerning backdrop of genetic erosion in indigenous poultry populations across India. The country is home to a diverse range of 19 recognized indigenous chicken breeds, each with unique traits developed over centuries of adaptation to local environments 1 .
These native breeds collectively represent an invaluable genetic reservoir containing traits for disease resistance, climate adaptability, and superior meat and egg quality that are often absent in commercial poultry lines 1 .
"Unlike commercial poultry lines, indigenous breeds are more suitable for extensive husbandry systems, making them ideal for resource-constrained poultry farmers" 1 .
Modern genetic characterization tools such as microsatellite markers, SNP genotyping, and whole-genome sequencing have revolutionized our understanding of indigenous poultry diversity 1 .
Research on Indian indigenous chickens has revealed that they share genetic affinities with Southeast Asian red jungle fowl (Gallus gallus), supporting the hypothesis of multiple independent domestication events in chicken evolution 1 .
The conservation of indigenous poultry genetic resources like the Khadia chicken has gained urgency amid the rapid expansion of commercial poultry production in India. Current findings indicate that despite their genetic richness, several indigenous breeds face the risk of genetic dilution and population decline 1 .
The comprehensive study of Khadia chicken populations in Northern Odisha serves as an excellent example of systematic agricultural research applied to indigenous genetic resources. The investigation employed a multimethod approach combining structured questionnaires, focal group discussions, and direct morphological measurements to gather both socio-economic and phenotypic data 3 .
Researchers employed structured questionnaires for socio-economic data and conducted focal group discussions to understand rearing practices and constraints 3 .
A sample size of 200 households rearing Khadia chickens was selected using appropriate sampling techniques to ensure representative data collection 6 .
Direct measurements of live birds were taken for quantitative traits including body weight, shank length, and keel length using standard measuring instruments 6 .
Collected information was subjected to statistical analysis to derive averages, variations, and significant differences compared to other native breeds like Hansli 6 .
This methodological rigor ensured that the research outcomes could serve as reliable baseline information for academicians, researchers, and breeders in developing future strategies for the improvement of native chicken populations 6 .
The comprehensive characterization of indigenous poultry populations like the Khadia chicken relies on a sophisticated array of research tools and methods. These range from basic morphological measurement equipment to advanced molecular genetic techniques, each playing a crucial role in understanding and preserving poultry biodiversity.
| Tool/Technique | Primary Function | Application in Khadia Research |
|---|---|---|
| Morphometric Instruments (measuring tapes, calipers, scales) | Recording physical dimensions and weights | Documenting body weight, shank length, keel length and other quantitative traits 3 6 |
| Structured Questionnaires | Collecting socio-economic and management practice data | Gathering information on household economics, rearing constraints, and traditional knowledge 3 |
| Statistical Analysis Software | Analyzing quantitative data and determining significance | Establishing performance benchmarks and comparing traits with other breeds 6 |
| Microsatellite Markers | Assessing genetic diversity and population structure | Understanding genetic variability and distinctness of indigenous breeds 1 |
| SNP Genotyping | Identifying single nucleotide polymorphisms | Detecting genetic variations associated with specific traits 1 |
| Whole-Genome Sequencing | Comprehensive genetic characterization | Identifying genes related to adaptation, disease resistance, and productivity 1 |
The integration of these tools enables a comprehensive understanding of indigenous poultry resources from both phenotypic and genotypic perspectives. As research advances, techniques such as genome-wide association studies (GWAS) and epigenetics are expected to provide further insights into the genetic basis of adaptive traits in breeds like the Khadia chicken 1 .
The story of Khadia chicken in Northern Odisha represents both the challenges and opportunities inherent in conserving indigenous poultry genetic resources. These birds embody a perfect adaptation to local environments and farming systems, providing crucial livelihood support for tribal communities while maintaining valuable genetic traits that may hold keys to future breeding advancements.
Looking ahead, the conservation of Khadia chicken and other indigenous poultry breeds requires a multifaceted approach that combines scientific research, policy support, and community engagement.
As Odisha strives for self-sufficiency in egg production 5 , indigenous poultry varieties like the Khadia should be recognized for their potential contribution to sustainable food systems.
By investing in the characterization, conservation, and improvement of these native genetic resources, we can support both the livelihoods of tribal communities and the long-term resilience of India's poultry sector.
The Khadia chicken, with its distinct characteristics and socio-economic importance, serves as a powerful reminder that the future of sustainable agriculture may depend on preserving the genetic heritage of the past.
