W.  aDetermining the digestibility and metabolizable energy of winter range plants by sheep.h[electronic resource]  c1952  aAbstract: Most important nutrients in appraising the value of range forage are: digestible protein, productive energy, phosphorus and carotene (vitamin A). Accurate appraisals of these constituents are needed for determining deficiencies of range forage, compounding supplements for range feeding, and for comparing the value of the various range plants. Generally, the ranges of the intermountain area do not produce forage that furnishes all the dietary needs of grazing animals during the winter grazing season. For optimum nutrition, supplementary feed must be supplied, and the amount and nature will depend upon the quality and quantity of forage consumed. Livestock operators in this area prefer to feed home-grown supplements, such as corn, barley and alfalfa which are relatively high in carbohydrates, rather than expensive protein supplements that must be shipped long distances. Therefore, it is important to evaluate the energy-supplying qualities of range forage rather accurately so that feeds prodiced at home can be used to a maximum.  aDigestible energy  aForage  aForage grasses  aGrazing  aNutrients  aPastures  aRangelands  aRuminant nutrition  aSheep  aDigestibilidade  aNutrição  aOvino1 aSTODDART, L.
