Broilers vs Layer Farming
Broilers and layers are two types of chickens that are raised for different purposes. Broilers are raised for meat production, while layers are raised for egg production. The differences between broiler and layer farming are significant and understanding them is important for anyone interested in poultry farming.
One of the main differences between broiler and layer farming is the purpose of raising the chickens. Broilers are raised for meat production, while layers are raised for egg production. This means that the two types of chickens have different breeds, growth rates, feed requirements, housing, lighting, space requirements, mortality rates, market values, lifespan, egg production, temperament and vaccination protocols. Understanding these differences is essential for anyone who wants to succeed in the poultry farming industry.
Broiler farming typically involves raising chickens in large open floor spaces or in cages, while layer farming often involves housing chickens in battery cages or free-range systems. Broilers grow at a faster rate than layers, reaching market weight in 6–8 weeks, while layers reach maturity at around 20 weeks. Broilers require a high-protein diet to promote muscle growth, while layers require a balanced diet that includes calcium for eggshell production. These and other differences between broiler and layer farming are important to consider when deciding which type of chicken to raise.
Purpose and End Product
Broilers and layers are two types of chickens that are raised for different purposes. The purpose of broiler farming is to produce meat, while layer farming is focused on egg production.
Broiler Production Goals
Broiler farming is done with the goal of producing meat. Broilers are typically raised for a period of 6-8 weeks and are sold for meat production. They are bred to grow at a faster rate than layers, reaching market weight in a shorter period of time. Broilers require a high-protein diet to promote muscle growth and are usually housed in large open floor spaces or in cages. They are raised with 24 hours of light to promote growth and require less space per bird compared to layers. However, broilers have a higher mortality rate compared to layers as they are raised at higher densities and are prone to health issues due to rapid growth.
Layer Production Goals
Layer farming is done with the goal of producing eggs. Layer chickens are egg-laying breeds that are typically raised for a period of 20 weeks or more. They require a balanced diet that includes calcium for eggshell production and a specific amount of light to encourage egg production. Layers are often housed in battery cages or free-range systems and require more space per bird compared to broilers. They have a longer lifespan compared to broilers, as they can produce eggs for up to 2 years. Layers are specifically bred for high egg production and require different vaccination protocols compared to broilers.

Genetics and Breeding
Broiler Breeding
Broiler breeding involves selecting and breeding chickens with desirable traits for meat production, such as fast growth rate, high feed efficiency, and large body size. The breeding process involves selecting parent birds with the desired traits and then mating them to produce offspring with those traits. This is done through a process known as selective breeding, which involves choosing the best birds from each generation to breed the next generation.
Broiler chickens are typically bred for meat production, and there are several breeds that are commonly used for this purpose. These breeds include the Cornish Cross, the Ross 308, and the Cobb 500. These breeds have been selectively bred to produce fast-growing birds with large amounts of meat.
Layer Breeding
Layer breeding involves selecting and breeding chickens with desirable traits for egg production, such as high egg production, good egg quality, and disease resistance. The breeding process involves selecting parent birds with the desired traits and then mating them to produce offspring with those traits. This is done through a process known as selective breeding, which involves choosing the best birds from each generation to breed the next generation.
Layer chickens are typically bred for egg production, and there are several breeds that are commonly used for this purpose. These breeds include the White Leghorn, the Rhode Island Red, and the Sussex. These breeds have been selectively bred to produce birds that lay large numbers of high-quality eggs.
In both broiler and layer breeding, genetics play a crucial role in determining the traits of the offspring. By selectively breeding birds with desirable traits, breeders can produce birds that are better suited to their intended purpose, whether it be meat production or egg production.
Housing and Equipment
Broiler and layer chickens have different housing requirements, as they are raised for different purposes. The following are the differences between broiler and layer housing systems:
Broiler Housing Systems
Broilers are typically housed in large open floor spaces or in cages. They require more space than layers, especially during the first few weeks of their lives when they are growing rapidly. Broiler housing systems are designed to provide adequate space, ventilation, and temperature control. The temperature of the broiler house should be around 32-35°C, and the humidity should be kept at around 60%.
Broiler houses are equipped with heating systems, such as gas heaters or electric heaters, to maintain the temperature. They also have ventilation systems, such as fans and air inlets, to provide fresh air and remove moisture and ammonia. Broiler houses are usually cleaned and disinfected between batches to prevent the spread of disease.
Layer Housing Systems
Layers are often housed in battery cages or free-range systems. Battery cages are small wire cages that provide a limited amount of space per bird. Free-range systems allow birds to roam freely and have access to outdoor areas. Layer housing systems are designed to provide adequate space, nesting boxes, and perches.
Layer houses are equipped with lighting systems to provide the required amount of light for egg production. They also have ventilation systems to provide fresh air and remove moisture and ammonia. Layer houses are usually cleaned and disinfected regularly to prevent the spread of disease.
In summary, broilers and layers have different housing requirements due to their different purposes and growth rates. Broilers require more space and a warmer environment than layers, while layers require adequate space, nesting boxes, and perches for egg production. Proper housing and equipment are essential for the health and welfare of both broilers and layers.
Feeding and Nutrition
Broiler Feed Requirements
Broilers require a high-protein diet to promote muscle growth. According to NavFarm, broilers require a diet that is high in energy and protein to quickly gain weight. This means that broiler feed is more expensive than layer feed. The amount of protein content in poultry feed affects its cost, so the higher the protein content, the more expensive the feed becomes.
Broilers require a starter feed that contains 22-24% protein for the first 0-10 days, a grower feed that contains 20-22% protein for the next 10-21 days, and a finisher feed that contains 18-20% protein for the final 21-42 days of growth. Broilers also require a diet that is balanced in terms of amino acids, vitamins, and minerals.
Layer Feed Requirements
Layers require a balanced diet that includes calcium for eggshell production. According to Anderson International, the feeding routine for laying hens typically involves a starter feed containing 18-20% protein for the first 6-8 weeks, a grower feed with a reduced protein content of 14-16% for the next 6-12 weeks, and a layer feed to prepare the pullet hen to begin laying her first eggs, typically around 16-18 weeks of age, by providing protein levels between 16-18%. Layer feed also contains calcium to promote eggshell production.
In addition to a balanced diet, layers require access to clean water. According to Bivatec, water is essential for egg production and should be provided to layers at all times. Layers also require grit to help them digest their food and produce strong eggshells. Grit is typically provided in a separate container or mixed in with their feed.
Health and Welfare
Disease Management in Broilers
Broilers are susceptible to several diseases due to their high-density rearing conditions. Common diseases include coccidiosis, infectious bronchitis, and Newcastle disease. Broilers are often vaccinated against these diseases to prevent outbreaks. However, the excessive use of antibiotics in broilers can lead to antibiotic resistance, which poses a substantial threat to global health. Therefore, it is essential to develop alternative disease management strategies that do not rely on antibiotics.
Disease Management in Layers
Layers are also susceptible to various diseases, including infectious bronchitis, Newcastle disease, and avian influenza. Layers are often vaccinated against these diseases to prevent outbreaks. However, layers are also prone to egg-laying disorders, such as egg binding and prolapse, which can lead to mortality. Therefore, it is essential to provide proper nutrition and housing to prevent these disorders.
Welfare Standards
The welfare of broilers and layers is crucial for their health and productivity. The European Food Safety Authority (EFSA) has developed welfare standards for broilers and layers, which include requirements for housing, lighting, ventilation, and stocking density. These standards aim to ensure that birds are kept in humane conditions and are not subjected to unnecessary stress or suffering. However, some current challenges relate to bird productivity and consumer preferences, as increased productivity can reduce bird health and meat quality.
