Metabolizable Energy of Some Oil Seed Meals and Some Unusual Feedstuffs

HILL and associates worked out a satisfactory basic diet and procedure for determining the metabolizable energy content of poultry feedstuffs (1958), and have reported the metabolizable energy of grain (1960a) and soybean products (1960b). The present study was undertaken to determine the metabolizable energy content of a number of oil seed meals (cottonseed, peanut, sesame, and safflower meals) and some other feeding stuffs (copra meal, fine and coarse rice bran, mungo beans, dried whole shrimp, ipil-ipil leaf meal) not commonly used in the United States but representing an important source of feeding materials for certain other parts of the world, especially in the Philippine Islands. As a part of this study it was decided to conduct complete proximate analyses on the various feedstuffs and, where digestibility values are available from the literature, to compare the metabolizable energy values estimated according to the method of Titus (1955) with those determined biologically…
