What You'll Learn
Local chicken breeds are hardy and disease-resistant
While there are hundreds of chicken breeds globally, only a few indigenous breeds are found in Africa. These include the Naked Neck, Venda, Ovambo, Potchefstroom Koekoek, and Boschveld breeds, which are the most common ecotypes in Southern Africa.
Local chicken breeds in Africa are hardy and can adapt to local conditions better than other breeds. They have the ability to withstand harsh climatic conditions due to their genetic makeup. They also possess a strong ability to anticipate danger and act quickly. For example, the Venda chicken has a light red-brown colour with white feathers in between that help camouflage and protect them from predators.
Local African chickens are also resistant to diseases. For instance, Egyptian Fayoumi chickens are less susceptible to diseases like Salmonella, coccidiosis, Marek’s Disease, Avian Influenza, Rous sarcoma virus, and virulent Newcastle disease (vND). They are also fertile, thrifty, heat-tolerant, and excellent at foraging and avoiding predators.
Despite their hardiness and disease resistance, local African chicken breeds are associated with low productivity. However, improvements in their productivity can be achieved by paying close attention to nutritional, breeding, and health aspects. For instance, efficient nutrition is an important factor in determining the performance and productivity of chickens.
In conclusion, local chicken breeds in Africa are hardy, disease-resistant, and provide a valuable protein source to rural households. However, to improve their productivity, there is a need to focus on efficient management, breeding, and nutrition practices.

Indigenous chickens are a valuable protein source
Indigenous chickens are a valuable source of protein for many communities in Africa. They are well adapted to hot, dry, and semi-dry environments, unlike their wild ancestor, the Red junglefowl, which lives in humid and sub-humid tropical areas. In tropical areas, most of the chickens comprise indigenous breeds.
Indigenous chickens are particularly important in rural sub-Saharan Africa, where they are a major source of animal protein. They also contribute to the income of poor rural households, with the consumption of indigenous chicken eggs and meat constantly increasing. In addition, chickens are used as gifts or sacrifices during festivals or traditional ceremonies, and they provide financial security to ensure children's school expenditure and other expenses.
In African countries, there has been little effort to conserve local chicken breeds. However, local chickens are hardy and provide a valuable protein source to rural households. They are also known to be disease-resistant, which is an important factor in determining their productivity.
The poultry population in Africa is composed mostly of local or indigenous chickens, which are appreciated for the unique taste and texture of their meat. However, with the ever-increasing population growth, the free-range or backyard poultry farming system is no longer adapted to supply people with protein requirements. Crossbreeding local hens with improved roosters weakens the thermotolerance and disease resistance of the offspring in African areas. Therefore, the available breeds need to be preserved, and their productivity should be improved through the implementation of sustainable production programmes that are simple and less expensive for farmers.

African chickens are genetically diverse and adaptable
African chickens are highly adaptable and genetically diverse. They are known for their hardiness and can adapt to local conditions better than other breeds. This is due to their ability to withstand harsh climatic conditions, which stems from their unique genetic development. They can survive in harsh tropical environments, enduring long arid seasons, excessive rain and humidity, and extreme heat. They are also resilient to diseases.
The adaptability of African chickens is a result of natural selection or artificial selection for production traits. Their genetic makeup has allowed them to anticipate danger and act quickly, further contributing to their survival in challenging environments.
Genomic analysis of Nigerian indigenous chickens, for instance, has revealed significant genetic diversity and adaptation to heat stress. These chickens exhibit remarkable thermotolerance and an enhanced immune response, with specific genes contributing to their ability to thrive in hot climates.
South African indigenous chickens also showcase genetic diversity and adaptability. The Venda chicken, for instance, is known for its egg-laying potential, self-sustainment, disease resistance, and low food requirements. Another example is the Ovambo chicken, which originated in Namibia and is characterised by its dark to black colouration with streaks of white or orange.
While African chickens are genetically diverse and adaptable, they often face threats from predators and emerging diseases. Additionally, market demands for specific breeds and rapid production can compromise the conservation of indigenous breeds and their valuable traits.

Conservation efforts for local breeds are limited
While there are hundreds of chicken breeds globally, only a few indigenous breeds have been identified in Africa, with many remaining unidentified and facing extinction. Conservation efforts for local breeds on the continent are limited. There has been little effort to conserve local chicken breeds in African countries, and very few conservation programmes are available in these regions.
Local chickens in Africa are hardy and can adapt to local conditions better than other breeds due to their ability to withstand harsh climatic conditions. They are also resistant to diseases and provide a valuable protein source to rural households. However, they are associated with low productivity, particularly in terms of the number of eggs laid.
To prevent the extinction of local breeds, the Food and Agriculture Organization has launched an indigenous poultry conservation programme. Additionally, the Agricultural Research Council in South Africa has established a programme to protect four local chicken breeds: Naked Neck, Venda, Ovambo, and Potchefstroom Koekoek. These upcoming ecotypes in Southern Africa have proven their importance in solving socio-economic problems in rural communities.
Despite these efforts, food security remains a challenge in many African countries. To improve the productivity of local chickens, close attention must be paid to nutritional, breeding, and health aspects. There has been a research gap in the genetic, physiological, and nutritional aspects of indigenous chickens in Africa over the past decade, with very few studies conducted on their nutrient requirements.

Improving productivity through efficient nutrition
There are hundreds of chicken breeds globally, and while chickens were first domesticated thousands of years ago, new breeds are still being developed. For example, in 1998, farmer Mike Bosch developed a new breed of chicken in South Africa by crossing three indigenous breeds: the Venda, Ovambo, and Matebele.
Chickens are commonly raised either for egg production or meat, and these two types require different feeding methods. Efficient nutrition is a key factor in improving the productivity of chickens, and the development of diets that match the nutrient requirements of these breeds is essential for the competitiveness of the poultry industry.
To improve chicken productivity, it is important to pay attention to the way chickens are fed, in addition to the feed itself. For instance, providing sufficient feeder space and placing the feeders at the level of the chickens' backs are important considerations. It is also crucial to store feed properly, as old feed can lose its nutritional value and become susceptible to mold.
The nutritional requirements of chickens vary depending on their life stage. For example, pullets should be fed to reach a certain body weight at a specific age, as insufficient body weight during the growing period can lead to problems in the laying flock. Additionally, molting, a natural process in chickens, can impact egg production. During molting, chickens experience a significant loss of body weight, and the regression of the reproductive tract plays a role in improving egg quality in the subsequent production cycle.
To enhance egg production, it is recommended to provide a balanced diet that meets the nutrient requirements of the chickens. While table scraps and scratch grains can be provided in limited quantities, excessive amounts can negatively affect egg production. Young, tender plants are a valuable source of nutrients, but old, fibrous plants should be avoided as they are difficult for chickens to digest.
In the case of chickens raised for meat, also known as broilers, nutritional strategies play a crucial role in improving meat quality and body composition. Appropriate nutritional interventions, such as modulating nutrient composition and supplementing bioactive compounds (vitamins, probiotics, prebiotics, polyphenol compounds, etc.), have been shown to positively impact the meat quality and yield of broiler chickens.
In conclusion, improving the productivity of chickens in Africa through efficient nutrition requires a comprehensive approach. This includes developing diets that meet the nutrient requirements of specific breeds, implementing proper feeding practices, and considering the life stage and specific needs of the chickens. By addressing these factors, it is possible to enhance both egg production and meat quality in local chicken breeds in Africa.
