Everyone knows that corn is the most important feed component for livestock producers. What is less known, though, is that the grain we call corn is currently almost an abstract entity. According to Dr Gustavo J. M. M. de Lima, a researcher at Embrapa/ CNPSA, Brazilian Agricultural Research Corporation-Swine & Poultry Research Centre, there is such a huge variation in its nutritional composition that the extremes barely resemble each other. Surprisingly enough, he states that we are neglecting the issue, much to the detriment of the sector. The problem acquires more relevance nowadays, given the high corn prices (and the prospects to remain high), the decreasing profit margins, and the impact of feed prices on production costs. Producers should be aware of various aspects of corn composition and pay the required attention.
