**1. Introduction**

The demand for poultry meat and other associated products has skyrocketed over the past few years. In 2020, there were 137 million tons of chicken meat produced globally, making it the most popular meat worldwide. Consequently, the chicken industry makes a significant contribution to the consumption of animal proteins, human nutrition, and global food security [1]. The world has seen a tremendous increase in the demand for poultry meat and other poultry feed with the advent of time. The trend of this growing demand will continue over time. It is not exaggerated to say that with the increase in demand, the production of poultry meat and egg has also increased in both developed and developing countries. In the next 20 years, it is predicted that a rapid increase in poultry production will take place in developing countries too because of rapid urbanization and the higher increase in animal protein demand. Globally, the poultry industry has grown quickly due to several factors, including improved knowledge of poultry feeding, genetic selection, and disease management. The main factor in improving egg and meat quality and quantity has been feed formulation [2]. For instance, the time it takes for a 2 kg meat chicken to reach the market has significantly

decreased from 63 to 35 days between 1976 and 2009, because of the efficient conversion of feed into poultry products. The need for feed and raw materials is significantly being impacted by this increase in poultry production. The key input for poultry production is feed; hence, low-cost, high-quality feeds must be readily available if poultry production is to remain competitive and expand to meet consumer demand for animal protein.
