Stress (due to heat, disease, illness or parasites)
Poor gut health
Pathogens: Bacteria, viruses or other microorganisms that can cause disease. Some common pathogen challenges for layers include:
Bacteria (e.g., Salmonella, E. coli, Clostridium, etc.)
Viruses (e.g., avian influenza, bronchitis, etc.)
Worms (e.g., roundworms)
Fungi (e.g., mycotoxins from molds)
Focal duodenal necrosis (FDN): An intestinal disease that layers are susceptible to and that is identified by many locations of necrosis throughout various parts of their intestines, primarily near the duodenal loop and the proximal jejunum. FDN can cause a decrease in egg size and a drop in egg production of up to 10%.
Sustainability: Overall, poultry are a very efficient and sustainable species — but there is always room for improvement. Sustainability in layers refers to maintaining the amount of egg production needed to efficiently supply the growing population with quality eggs while also maintaining high-quality animal welfare. Housing systems and other processes are constantly being evaluated based on their performance and efficiencies to help determine how sustainability can be improved.
Tips for maximizing health and performance
Provide antioxidants and minerals that are better absorbed to increase mineral reserves.
Implement a gut health program that supports the creation and maintenance of a diverse microbiota and enhances the surface area of the gut.
