Introduction:
Chickens or turkeys raised specifically for meat are commonly referred to as broilers. Broilers are a type of poultry bird that is bred and raised for their meat production. They are genetically selected and specially bred to grow rapidly and efficiently convert feed into muscle tissue.

Explanation:
Broilers are the most commonly used birds for meat production worldwide due to their fast growth rate and high feed conversion efficiency. The term "broiler" refers to any bird that is raised for meat, whether it is a chicken or a turkey.

Key Points:
- Broilers are specifically bred for meat production and have been genetically selected to grow rapidly.
- They are typically ready for slaughter at around 6-7 weeks of age.
- Broilers are raised in large-scale commercial operations known as broiler farms, where they are housed in controlled environments such as temperature-controlled barns.
- These birds are provided with a balanced diet that is specifically formulated to meet their nutritional needs and promote rapid growth.
- The feed given to broilers typically consists of a combination of grains, protein sources, vitamins, and minerals.
- Broilers are known for their high feed conversion efficiency, meaning they can convert feed into muscle tissue at a relatively fast rate.
- Due to their fast growth rate and efficient feed conversion, broilers are able to reach market weight quickly, making them an economically viable option for meat production.
- The meat from broilers is commonly consumed by humans and is used in a variety of dishes and food products.

Conclusion:
Chickens or turkeys raised specifically for meat are called broilers. These birds are bred and raised for their meat production and have been genetically selected to grow rapidly and efficiently convert feed into muscle tissue. Broilers are a common choice for meat production due to their fast growth rate and high feed conversion efficiency.
