Applied Animal Nutrition-I

MORRISON FEEDING STANDARD

• Morrison F.B. observed that stockmen are spending large sums of money for entirely unnecessary amounts on protein supplement, thus considerably reducing their profits.

• He therefore, endeavoured to combine in one set of standards what seem in the judgment to be the best guide available in computation of rations for the various classes of livestock.
• These standards were first presented in the 15^th edition of “Feeds and Feeding” published in 1915 under the authorship of Henry and Morrison. They  were then called “Modified Wolff and Lehmann standard”.
• They soon came to be known as the “Morrison Feeding Standard”.
• These standards were expressed in terms of Dry Matter (D.M.), Digestible Protein (D.P.) and Total Digestible Nutrients (T.D.N.).
• Morrison indicated  the nutrient  requirement of animals in a range rather than in one figure. 
• In the year 1956, Morrison included in the standard the allowances for Calcium, Phosphorus and Carotene besides digestible carbohydrates, digestible proteins and net energy in therms.
• The average of Morrison standards has been accepted for Indian livestock.
