I am making a recipe for some feed. I feel I am on the right track. I have the help of a program that shows me protein, calcium and phospurus amounts. I know I need a 2:1 Ca/P ratio. The problem is, all the high Ca (calcium) content comes from the really expensive grains. Corn is still the cheapest thing to add but it is so high and phosphorus and barely any calcium at all so that throws off the ratio. I know I can add feed grade lime ,which is calcium carbonate, to the feed mix and that allows me to get the level where it needs to be and lets me use a little more corn and a little less alfalfa pellets to save some money. Is limestone calcium carbonate added to the feed an OK source for calcium or should I make the feed be correct with the grains and without adding the lime? Also, I've added some soubean meal to get the protein up a bit. This is going to be a dusty feed unless I add a binding agent like molasses or something. However, that causes the feed to have a much lesser shelf life. I want to order at least a 1/2 ton mixed. What would you suggest I do about cutting the dust without taking shelf life away? I almost have this recipe ready but I have to figure out these last few things before I can move forward. I looked up quite a few recipes on past threads and when I ran the recipe through the program, many of them were so high in phosphorus and were too low in calcium. Too much phorphorus is the main cause for urinary calculi in male goats....at least around here. Thanks for your help!!
