摘要：Today, we heard three very different papers on the Mexican Grain/Livestock Subsector, but they complement each other very well. Avalos' paper gave us a general overview of the grain and animal feed subsectors in Mexico. It is worth noting how heterogeneous grain production is in Mexico, as shown by the extremely wide range of profitability levels. Depending on location, the production system utilized, yields, and other factors, there are farmers with negative rates of return on investment while others experience rates of return as high as 95 percent.
