Corn (maize) is the Major energy source ingredient in the poultry production, the approximate total world production 1044,556 million metric ton in 2017/ January 2018, Chart (1) shows the largest 17 countries in yellow corn production in 2017/ January 2018, United States the largest producing country in world with total production of 370,960 million metric ton, China comes at the second place with total quantity of 215,891 million metric ton (USDA foreign agriculture services -February 2018 report).

The feed industry usually uses the equivalent of United states grade number 2. As grade number increase specification declines, world food program ( publish technical specifications of yellow corn grade number 2 from different sources those specification will affect the price per metric ton. Damaged kernels and foreign materials are going to reduce the economic value of corn. Depending on the growing season and storage and shipping conditions mold and associated mycotoxin can be a problem. Table 1 explains some general requirements and the limitation of contamination for corn according to technical specification.

The large yield gap between the maize producing countries, a relatively more recent development with important implications for production as well as trade and marketing, has been the “biotechnology revolution”; a development which resulted in the spread of the Genetically Modified (GM) maize, the GM seeds were first introduced on a commercial scale in 1996 in the United States and 95 % from the global production of yellow corn is genetically modified organism (GMO) including  resistance to pests and to herbicides.
