Nitrogen metabolism has been extensively studied in animals fed at a level adequate to maintain moderate or high levels of production. Much less attention has been given to events in the digestive tract of animals struggling to maintain some productivity or in some instances having difficulty surviving because of the low plane of nutrition available to them. Yet for part of every year this is the fate of nlIninants in subtropical and tropical regions which support the bulk of the worlds' population both of humans and of herbivores. These animals depend almost entirely on nutrients obtained from natural pastures which rise and fall in nutritional value according to the season. As the rainy season is replaced by a dry period soil moisture becomes inadequate to support plant growth.
