By 2030, the world’s population is expected to exceed 8.5 billion, which means the need for cost-effective and nutritious animal protein is rising rapidly. Eggs play a vital role in meeting this demand as one of the most affordable and accessible sources of nutrition worldwide, fitting into almost any diet. This presents an opportunity for producers to generate more eggs, produced more efficiently. The answer lies in improving laying persistency.
Cargill Animal Nutrition & Health is pioneering efforts in this area, not only by researching methods to produce more eggs but by translating those insights into practical strategies that support global producers aiming for better laying persistency and clear returns on investment (ROI). Let’s delve deeper into this topic.
Why Laying Persistency Matters
Persistency serves as both a performance metric and a profitability driver. When laying hens produce eggs consistently and live longer, producers can defer the large costs associated with flock replacement. Depending on feeding strategies, these persistent hens may also incur lower feed costs per egg, enhancing both efficiency and sustainability. In a market characterized by slim margins and high pressure, maintaining steady production is essential for long-term success.
This raises an important question: How do we keep layers productive for longer without compromising health or efficiency?
How Many Eggs Can a Healthy Hen Actually Lay?
The egg production capacity of hens has significantly increased over the last fifty years. In the 1960s, it was around 220 eggs, but by 2019, that figure had soared to 500 eggs. This increase represents a remarkable benchmark for global egg production, yet achieving such persistency depends heavily on science-backed nutrition strategies that protect health and performance over time. To understand this, we must explore the research.
Modern laying hens can produce up to 500 eggs in 100 weeks, but maintaining this level of production requires carefully structured nutrition strategies that meet the immediate and long-term needs of the birds.
Breakthrough Research by Industry Experts
To uncover the driving factors of persistency, scientists at Cargill conducted a unique 110-week study at their global innovation center in the Netherlands. The results, published in Poultry Science, highlighted two crucial insights:
- Investing in the rearing period is essential: Hens fed diets low in amino acids during their rearing phase exhibited smaller body weights and diminished laying persistency beyond 100 weeks. This underscores the need for adequate early nutrition to set up hens for long-term success.
- Energy and lipid levels during laying influence performance: Diets with limited oil content reduced laying periods, decreased egg weights, and shifted fat storage to the liver, adversely affecting efficiency and persistency. Notably, fat metabolism emerges as a vital aspect of egg production, with hormones derived from fat tissues linked to body weight and egg mass.
These findings emphasize the importance of crafting tailored nutrition strategies throughout the hens’ lifecycle—not just during peak production. Persistency begins well before the first egg is laid.
From Science to Solutions
Cargill’s research provides a robust foundation for effective solutions. They integrate science-backed nutrition programs with proven products that support healthy, productive flocks while leveraging expertise from professionals who understand poultry challenges. Key offerings include:
- Programs that are empirically validated in real-world conditions to support productive flocks.
- Dedicated experts who collaborate with producers to apply findings in practical settings.
- Innovative decision-enabling platforms like Reveal Layers, which enable real-time monitoring of hen body conditions to facilitate strategies that enhance persistency while reducing feed costs.
The Role of Reveal Layers
Reveal Layers introduces a groundbreaking non-invasive near-infrared (NIR) technology for monitoring poultry body condition. This innovative approach empowers poultry producers by:
- Enabling real-time decision-making: Produce immediate data on body condition for precise dietary adjustments based on flock insights.
- Supporting long-term egg production: Maintaining optimal body condition ensures sustained egg production while fostering good health in hens.
- Enhancing profitability: The integration of Reveal Layers with Cargill’s nutritional competencies enables producers to lower feed costs while boosting egg yields.
The Practical Impact
Improved persistency translates to more eggs per hen, elevated feed efficiency, and a stronger ROI. By linking research to actionable tools, producers can reach new performance levels, even in challenging conditions. This is how Cargill ensures measurable impacts throughout the poultry value chain.
