What is the typical crude protein percentage required for growing poultry?

The typical crude protein percentage required for growing poultry falls within the range of 18-24%. This is because growing poultry, such as chicks or young birds, require higher protein levels to support their rapid growth and development. Protein is essential for muscle development, feathering, and overall health, thus influencing the growth rate and feed efficiency of these birds.

In contrast, the other ranges do not provide sufficient protein for optimal growth during this crucial life stage. Lower percentages like 10-15% or 15-20% might be adequate for maintenance or older poultry but would not support the needs of growing birds effectively. Similarly, while 25-30% might seem beneficial, it could lead to excessive protein intake, resulting in health issues and inefficient feed utilization due to the associated high nitrogen excretion. Therefore, the 18-24% range is well-balanced to promote healthy growth without unnecessary excess.
