The Metabolizable Energy of Soybean Oil Meals, Soybean Millfeeds and Soybean Hulls for the Growing Chick

PREVIOUS reports from this laboratory have described studies of methods of determining energy values for chickens (Hill and Anderson, 1958), determination of the metabolizable energy value of glucose (Anderson, Hill and Renner, 1958), and the metabolizable energy values of grains and grain products for growing chicks (Hill, Anderson, Renner and Carew, 1960). The purpose of this paper is to report studies of the metabolizable energy of soybean oil meals, soybean millfeeds and soybean hulls, materials widely used in poultry feeding, as part of a systematic study of the energy values of feedstuffs for poultry. MATERIALS AND METHODS In all of the experiments to be described, the reference diet employed was diet E9, the composition of which is shown in Table 1. It was formulated to contain adequate amounts of all known nutrients required by the chick, and was liberally supplemented with fish meal, fish solubles, brewers’ dried yeast and dried …
