CAFE, MB et al. Determination of the Nutritional Values of Processe Full-Fat Soybeans for Poultry. Rev. Bras. Cienc. Avic. [online]. 2000, vol.2, n.1, pp.67-74. ISSN 1516-635X.  https://doi.org/10.1590/S1516-635X2000000100010.

Three-assay birds were conducted to evaluate the contents of metabolizable energy and ether extract digestibility of processed full-fat soybeans by extrusion, by toast and of the soybean meal plus oil. Two assays were carried out by using the traditional total excreta collection by chicks and by rooster, and the other assay was developed by using the force-feeding adult rooster method (Sibbald, 1976). The results showed that the feed composition of the soybean-tested were similar. The different processing caused differences on digestibility of the nutrients of the soybeans tested and the value of coefficients of the nutrients in extruded soybean and soybean meal plus oil were higher than that heated soybean. The value of metabolizable energy was superior in extruded soybean.

Palavras-chave : digestibility; full-fat soybean; metabolizable energy; soybean extruded; soybean roasted.
