Leg Problems in Broilers: A Challenge for African Poultry Farmers

Leg difficulties, commonly known as Avian Skeletal Disorders (ASD), provide a substantial challenge to African broiler farmers, affecting bird welfare, production, and overall profitability. This article explores the primary causes (etiology) and control approaches for leg issues in broilers in the African context.

Understanding the causes: A multifaceted issue.

Leg issues in broilers are caused by a complicated interaction of several factors. Here are some major contributors:

Nutritional deficiencies: Low amounts of calcium, phosphorus, vitamin D3, and vitamin C can cause weakening bones, cartilage degeneration, and skeletal abnormalities. This is especially critical in Africa, where access to high-quality, balanced feed may be limited, and traditional feed sources may be deficient in essential nutrients.
My cotoxins: these are poisonous fungal pollutants found in inadequately stored feed. Mycotoxins affect bone growth and metabolism, causing leg pain. Warm and humid conditions common in many parts of Africa can promote fungal growth, raising the danger of mycotoxin exposure.
Management techniques: Leg difficulties can be caused by improper brooding temperatures, inadequate lighting, overpopulation, and poor litter quality. These variables can put strain on the birds’ skeletal systems, preventing healthy development.

Genetic factors: Because of their quick growth rate, certain broiler breeds are more prone to leg issues. While genetic selection for better leg health continues, it is also critical to address other contributing variables.

To address leg problems in broilers, a comprehensive approach is needed that addresses multiple contributing factors.

Infectious diseases: Diseases caused by viruses like Infectious Bronchitis Virus (IBV) and bacterial infections like Osteomyelitis can damage bones and joints, causing disability and leg abnormalities.

Controlling Leg Problems: A Multifaceted Approach
Addressing leg abnormalities in broilers requires a comprehensive approach that addresses multiple contributing factors:
Nutritional management : is entails ensuring a well-balanced diet rich in calcium, phosphorus, vitamins D3 and C, as well as other necessary components. Supplementing with these vitamins in water might be useful, especially during times of stress.
Mycotoxin control: Proper feed storage methods, such as keeping the feed cool and dry, utilizing airtight containers, and using antifungal treatments, can considerably reduce mycotoxin contamination.
Improved management: Optimal brooding temperatures, optimum ventilation, adequate illumination, and high-quality litter are critical for healthy leg growth. Maintaining adequate stocking densities to reduce stress on the birds’ skeletal systems is also critical.

Vaccinations: Implementing an effective immunization program against common diseases such as IBV will help reduce leg problems caused by these infections.

Genetic selection: While breeding for greater leg health is a long-term strategy, adopting broiler breeds known for superior leg function can help in the meanwhile.

African Context: Addressing Specific Challenges

Limited access to high-quality feed: Cost-effective, balanced feed formulations containing important nutrients are critical. Governments and research organizations can help to increase access to such feed and develop locally sourced, nutrient-dense supplements.
Knowledge and expertise: Farmers must be trained in proper broiler management procedures including as diet, housing, and disease control. Educational programs and extension services can help farmers adopt optimal practices for preventing leg disorders.

To clarify, leg difficulties in broilers have emerged as a major challenge for the African poultry sector in recent years. Farmers can adopt effective control strategies by knowing the various etiological factors, such as nutritional deficits, management flaws, and infectious illnesses. The strategies include the most effective feeding practices, improved broiler housing and management, illness prevention through immunization, and efficient mycotoxin control.  Farmers, veterinarians, dietitians, and legislators must all collaborate to address this complex issue. Working together, they can create and implement effective measures to protect broiler health, welfare, and profitability in Africa’s growing chicken industry.
