Broilers, or meat chickens, are highly susceptible to various diseases that can have a significant impact on their health and overall productivity. As a broiler farmer, it’s crucial to be aware of these diseases and take proactive measures to prevent and control them. In this article, we will explore the most common diseases that can kill broilers and discuss effective prevention and treatment strategies.
Introduction
Raising broilers for commercial purposes requires diligent management to ensure their well-being and optimal growth. However, the poultry industry faces several challenges, including the threat of diseases. Several diseases can affect broilers, leading to severe health issues and even death. It is essential for broiler farmers to understand these diseases, their signs and symptoms, and how to prevent and control them.
Common Diseases in Broilers
Infectious Bursal Disease (IBD)
IBD, also known as Gumboro disease, is a highly contagious viral infection that primarily affects young broilers. It targets the bursa of Fabricius, a vital organ responsible for immune system development. IBD weakens the immune system, making broilers more susceptible to secondary infections.
Newcastle Disease
Newcastle disease is a highly contagious viral infection that affects a wide range of bird species, including broilers. It can cause respiratory distress, nervous system disorders, and high mortality rates in infected flocks. The virus is easily spread through respiratory secretions, feces, and contaminated equipment.
Avian Influenza
Avian influenza, or bird flu, is a viral infection that can affect both wild birds and domestic poultry, including broilers. It can cause severe respiratory distress, decreased egg production, and high mortality rates. Some strains of avian influenza can also pose a risk to human health.
Marek’s Disease
Marek’s disease is a highly contagious viral infection caused by the herpesvirus. It primarily affects young broilers and leads to tumors in various organs, including the liver, spleen, and reproductive organs. The disease weakens the immune system, making broilers more susceptible to other infections.
Coccidiosis
Coccidiosis is a parasitic disease caused by protozoan parasites of the genus Eimeria. It affects the intestinal tract of broilers and can lead to severe diarrhea, weight loss, and decreased feed efficiency. Infected birds may become weak and susceptible to secondary infections.
Infectious Coryza
Infectious coryza is a bacterial respiratory disease that affects broilers, causing nasal discharge, swollen eyes, and reduced appetite. It is highly contagious and can spread rapidly within a flock, leading to decreased productivity and increased mortality rates.
Infectious Bronchitis
Infectious bronchitis is a viral respiratory disease that affects broilers, causing respiratory distress, nasal discharge, and decreased egg production in laying hens. It is highly contagious and can result in significant economic losses for broiler farmers.
