Business letter Dear Mr. Roy, Thank you for your attention since our first contact, I have made some improvements and I would like to discuss to you about new doubt that I´ve got. The first one is about the inclusion of Soybean hulls and Corn gluten feed 21%CP, what is the maximum percentage that we can use? You can use as base the Die Specs that I sent you. The second is about the formula of ROC, you told me that it´s possible to produce in the same facility both, pellets and ROC, If we just toggle the diet (wich can leads few minutes or some hours), so, I would like to see again those examples that you showed me because I never had created a Roc formula. Thanks in advance for your assistance, I look forward to your reply. JR.
