A more as protective measures against crude protein values of browse and green plants indicate that poor condition in animals is more likely due to lack of carbohy- drates and total digestible nutri- ents than to low crude protein percentage in the forage (Heady, 1960). Estimates of nutritive values (Glover and Dougall, 1961) showed that pasture for- ages containing 11 to 14 percent crude protein were most effi- cient for milk production. As milk is one of the most important food items for the Masai, man- agement of their ranges should aim for both high quality and quantity forage.
