Show VAULE OF THE CONCENTRATES Cotton Seed Meal Contains About S40 Pounds of Protein In Ton Valuable Valu-able Food Constituent ' (Br R a. WEATHERITTONE.) " The concentrates are usually bought for the protein which they contain. They also contain carbohydrates and oil. which are valuable aa food constituents. con-stituents. These make up the food value of the purchased concentrates. To the farmer they may have another value which Is not usually considered. We take cotton aeed meal and from the feeders' standpoint we find that A ton contains about 840 pounds of protein, pro-tein, the most valuable food constituent. constitu-ent. We will take 840 pounds of protein and scientists tell us that It contalna 1C per cent, of nitrogen, the most vsl-uable vsl-uable element In commercial fertilizer. Slxten per cent, of 840 is 134 4. Thus we find that In every ton of cotton seed meal we buy we get 134 4 bushels or nitrogen, which Is worth at least 15 cents per pound. The nitrogen nit-rogen In the ton of cotton seed meal alone. If purchased as commercial fertilizer, fer-tilizer, la worth $2016. Then If we add 40 pounds of potash and 40 pounds of phosphoric acid, w hich the ton of cotton cot-ton seed meal also contains, at five centa per pound or $4 additional, which brings the ton of feed to $24 18 vslue for the fertilizer alone. If the meal Is fed to the stock and the manure carefully saved It Is possible pos-sible to save 70 per cent, of the fertilizer ferti-lizer value and also get the full feeding feed-ing value of the material. Seventy per cent, of $24.16 la $16 91. Indirect value of a ton of cotton seed meal We may estlmste the Indirect or nitrogen value of any feed stuff If the protein content Is known by simply sim-ply finding 16 per cent, of the protein and calling It nitrogen. Then the anv.unt recovered In the manure Is from 70 to 90 per cent., according to the age and kind of animal to which It Is fed. A young animal will retain more of the nitrogen of the food than a mature animal. A cow will retain wore than other animals. The economy of live slock on the farm la largely due to the fertlllrer left on the farm from their feeding. |
