“…Kim et al (2000) also found that extruded soybeans had greater GE digestibility than roasted soybeans. Furthermore, Featherston and Rogler (1966) reported that extrusion caused the oil seed cells to rupture, and the subsequent release of oil increased fat digestibility when the soybeans were fed to chickens.…”

We conducted three experiments to determine the apparent ileal digestibility of amino acids (Exp. 1), metabolizable and digestible energy (Exp. 2), and feeding value (Exp. 3) of dry extruded-expelled soybean meal with (DEH) or without (DENH) hulls compared with solvent-extracted soybean meal with hulls removed (SBMNH). Soybeans used to produce DEH were unadulterated prior to extrusion, but those used for DENH were dehulled prior to extrusion. In Exp. 1, six nonlittermate barrows (initially 39 kg) were fitted with ileal T-cannulas and used in a replicated 3 x 3 Latin square design digestion trial. Experimental diets (0.80% total lysine) were cornstarch-based and contained soybean meal from one of the three different sources as the sole source of lysine. Apparent ileal digestibilies of nutrients were similar (P > 0.10) for DEH and DENH. Apparent ileal digestibilies of CP, Lys, Ile, Leu, Arg, Phe, and Val were greater (P < 0.05) for DEH and DENH than for SBMNH. In Exp. 2, six barrows (initially 41 kg) were fed three corn-based diets containing 25% of one of the three soybean meal sources. A fourth diet was fed at the end of the trial containing all ingredients except soybean meal, so that energy values of the soybean meal could be determined by difference. Digestible energy and ME contents were similar (P > 0.10) for DEH and DENH and both had greater (P < 0.05) DE and ME contents than SBMNH. In Exp. 3, pigs (n = 216, initially 10.6 +/- 1.3 kg and 35 +/- 3 d of age) were blocked by weight and allotted to six dietary treatments. Corn-soybean meal-based diets (0.95% digestible lysine and 3.44 kcal/g ME) containing DEH or DENH were compared with similar diets containing SBMNH or solvent-extracted soybean meal with hulls (SBMH). In addition, a diet containing a second expelled soybean meal with hulls (ESBM) was compared with a diet containing SBMH and soy oil. Growth performance of pigs fed diets containing DEH or DENH was not different (P > 0.10) than that of pigs fed corresponding diets containing SMBH or SBMNH. Pigs fed ESBM had lower (P < 0.05) ADG and G/F compared with its corresponding SBMH and soy oil diet. In conclusion, DEH and DENH are more digestible than conventional soybean meal and can be successfully used in swine diets.

“…Three basic cooking methods have been developed which destroy the growth inhibitors. Featherston and Rogler (1966) reported that pelleting the diet containing soybeans cooked in a gas-fired infrared cooker, regrinding and feeding as mash markedly improved chick performance. Stephenson and Tollett (1959) were one of the first groups to successfully show that full fat soybeans could be used in poultry diets if cooked properly.…”

Effects of Pelleting and Particle Size on Utilization of Roasted Soybeans by Broilers

Two experiments were conducted to evaluate full fat soybeans cooked in a commercial gas-fired cooker (Roast-a-Tron) as a protein and energy source for broilers. In the first study, fineness of grind of the cooked beans had little effect on body weight gains and nitrogen retention when fed in mash diets. However, the fat digestibility was markedly improved by increasing the fineness of grind. Pelleting the diets containing roasted soybeans significantly improved 7-24 day gains and feed conversion ratios as compared to their mash counterpart.A second study to eight weeks of age demonstrated that broilers can be fed diets containing roasted full fat beans to market weights when the diets are pelleted. ABSTRACTTwo commercial fermentation products, Vigofac and Fermacto-500, were tested in diets for turkey breeder hens to determine if they would have any influence on reproductive performance. These were tested in separate studies and were used to supplement both corn-soy diets and diets containing 5% fish meal.Vigofac at 1% of the diet supported a significantly higher rate of hatchability when added to corn-soy diets and a numerical but non-significant improvement when added to diets with fish meal. Fermacto-500, fed at 0.075% of the diet, significantly increased the number of eggs per hen when added to diets with fish meal with a numerical but nonsignificant improvement in production when added to corn-soy diets. The use of these or similar types of commercial fermentation products may be of value in supplementing the diets of breeder hen turkeys.

“…More recently, infra-red cooking has been evaluated as a means of processing unextracted soybeans for poultry (Featherston and Rogler, 1966). Chicks fed infrared heated beans grew as rapidly as those fed a corn-soybean meal diet.…”
