Broiler chicken hormone injection is used for growth and development of chicken. But, have you ever thought how actually does it work in chicken? Is it silent agent behind rapid growth of chicken? Hormone injection for broiler chicken goes through different paths to give a better result. Let’s discuss them.

Firstly, broiler chicken hormone injection is injected in chicken either through subcutaneous or intramuscular way. The injected solution will enter blood stream through capillaries. It will travel in blood stream to look for a target such as organ and tissue; a growth hormone receptor station.

In liver, there is growth hormone receptors therefore hormone will bind to receptor that will activate insulin-like growth factor 1. This is responsible for muscle development or growth. It will travel to its target that is muscle. From this point, actual growth process initiates. What’s next?

As IGF-1 acts as a messenger for cell to start growing. In muscle cells, it binds to insulin-like receptors. It is like unlocking a door. Cells get signals to start cell division, protein synthesis and absorb more and more nutrients.

You will see effects in a week tat chicken starts getting weight; rapid growth of breast or muscles. It results in unnatural fast growth of broiler chicken.
