Show Best to Compound Grain Mixture for Dairy Cow? In making a ration, cost Is one of the Important factors. The best practice prac-tice Is to compound a grain mixture so that It will balance with the home grown roughage. With this In mind the separate grains should be selected to supply the necessary nutrients at the lowest possible cost. For this, not only the price per hundred pounds but also the relative cost of each constituent, constit-uent, especially protein, must be con sldered. For example, to determine the cost of a pound of digestible protein pro-tein In a given feed divide the price of 100 pounds by the per cent of digestible di-gestible protein iu the feed. If this calculation Is made for several feeds, the relative cost of protein in ench will be apparent. Then the feeds that furnish protein at the least cost can be selected. The same can be done to determine the cost of the carbohydrates carbohy-drates and fat, which are the heat-making heat-making or energy-producing part of the feed. |
