More and Better Chicks: A Precision Approach to Breeder Nutrition

In Brief:

• In modern poultry production systems, success begins well before hatch. The quality of the day-old chick is a key determinant of broiler performance, mortality, flock uniformity, and ultimately profitability across the entire production chain.
• While global demand for broiler meat continues to increase, the supply of hatchable eggs is often constrained. Breeder performance has traditionally been measured by egg production and chicks per hen housed, but in modern systems, chick quality is just as important as chick quantity.
• Producing more chicks is not enough — producers must produce more high-quality chicks capable of strong early development and efficient growth.

Understanding the Drivers of Chick Quantity and Quality

Several biological and management factors influence breeder productivity and chick quality, including fertility, hatchability, egg production, and embryo development.

From a fertility perspective, sperm cells are highly susceptible to oxidative stress, which can reduce viability and fertilization success. In addition, mating challenges may occur when breeder body weight and flock uniformity are not optimally managed, particularly as birds age.

Hatchability is also influenced by the structural integrity of the egg. Weak vitelline or shell membranes can negatively affect embryo protection and development. These membranes are essential for maintaining the correct environment within the egg and supporting normal embryonic growth.

Egg production itself is closely linked to physiological processes such as plasma calcium availability and the balance between osteoblast and osteoclast activity, influence eggshell formation. Eggshell membrane quality and egg cleanliness also play important roles in determining hatch success.

Chick quality, meanwhile, is influenced by several factors, including genetics, egg size, immune status, egg nutrient composition, and the length of the hatch window. Together, these elements determine both the number of chicks produced and their ability to thrive after hatch.

Nutrition Across the Breeder Lifecycle

Achieving consistent breeder performance requires nutritional support across all phases of production — from early lay through peak production and into the later stages of the flock cycle.

Targeted nutrients and functional ingredients can play an important role in supporting these biological processes.

For example, 25-hydroxyvitamin D₃ (25-OH-D₃) supports calcium and phosphorus metabolism, helping optimize eggshell formation while also supporting skeletal and immune development in the embryo. Proper mineral metabolism is essential for both the breeder hen and the developing chick.

Carotenoids provide antioxidant protection that can help protect both sperm cells and developing embryos from oxidative damage. Antioxidant support is particularly important in modern high-performance breeder flocks where metabolic activity is high.

Trace minerals also play a critical role. Copper, for instance, contributes to lysyl oxidase activity, an enzyme involved in cross-linking collagen and elastin fibers. This process is essential for strengthening the vitelline and shell membranes that protect the developing embryo.

Nutritional strategies can also influence late-stage embryo nutrient absorption, supporting optimal chick development during the final stages of incubation.

These mechanisms work together rather than in isolation. By addressing multiple biological pathways simultaneously, nutrition can help improve overall reproductive performance and chick quality.

Managing External Challenges

While nutrition is a powerful tool, breeder performance is also influenced by external stressors that can compromise productivity.

Mycotoxin contamination remains a major challenge in many regions and can negatively affect reproductive performance, immune function, and egg quality. Effective mycotoxin risk management is therefore essential for protecting breeder health and maintaining consistent hatchability.

Gut health also plays a critical role in breeder productivity. A healthy intestinal environment supports nutrient absorption and overall bird health, which ultimately influences egg quality and embryo development.

Addressing these factors alongside targeted nutritional strategies helps ensure breeders can perform consistently under commercial production conditions.

Looking Ahead: Resilience in an Uncertain Market

The global poultry industry continues to face significant volatility. Avian influenza outbreaks, evolving animal welfare regulations, and shifting market dynamics are reshaping the economics of chick production.

Regulatory changes in several regions, including the adoption of in-ovo sexing technologies and restrictions on male chick culling, are likely to influence hatchery operations and chick supply.

At the same time, the cost of fertile eggs and day-old chicks remains elevated in many markets. This reality reinforces the importance of maximizing efficiency at the breeder level.

Under these conditions, precision nutrition becomes an increasingly important tool for poultry integrators seeking to maintain productivity and resilience in a challenging environment.

Unlocking More Value from Every Breeder

The More & Better Chicks approach is not simply about increasing output. It focuses on improving both the quantity and the quality of chicks produced, enabling stronger performance throughout the broiler production cycle.

By supporting fertility, embryo development, hatchability, and early chick vitality, breeder nutrition strategies can have a lasting impact on production efficiency and flock performance.

As the poultry industry continues to evolve, integrating science-driven nutrition, precision feeding strategies, and targeted functional ingredients will be essential for maximizing breeder potential.

Innovative nutritional solutions, such as MaxiRepro™ Poultry, are designed to support these goals and help producers consistently deliver more viable chicks and stronger broiler performance across the value chain.
