Foliage of certain forage trees and shrubs, being tried in the Range Management farm at the Pakistan Forest Institute, has been chemically analysed for the estimation of nutritive value. Range of nutritive constituents of these forages has been compared with those of the common grasses of Thai, Cholistan and Kala Chitta areas. It has been concluded that since the nutritive components of these forages compare favourably well with those of the common grasses, already supporting large herds of cattle, and since no toxic component exists, these forages, by virtue of their narrow range of nutritive ratio (ratio between proteins and total energy producers )' are capable of supporting growing calves and cows in milk.
