@goatgurl how did you can sausage? In water? Lard?

Raw soybeans contain several anti-growth factors, so the beans must be cooked before they are used in all pig diets except diets for gestating sows. Properly cooking the soybeans with either a roaster (240°F to 250°F for 2.5 to 3.5

minutes) or an extruder (exit temperature of 280°F to 300°F) destroys several of these anti-growth factors and produces an acceptable supplemental protein source for all pigs.
Less heating time is required to adequately destroy the anti-growth factors when sodium metabisulfate is added to the soybeans (at levels of 1 percent to 2 percent) before cooking. Recent research suggests extrusion processing yields soybean products of greater nutritional value for weanling pigs than does roasting. Grain driers do not adequately cook soybeans.
Among the anti-growth factors in soybeans is a compound known as Kunitz trypsin inhibitor. New strains of soybeans have been developed that do not contain the Kunitz inhibitor, so these newer varieties should require less cooking. However, current research indicates these new strains must be cooked to the same extent as regular soybeans if they are intended for weanling or growing pigs (12 lb to 120 lb). For finishing pigs only one half the cooking time may be necessary to achieve similar efficiency of growth as fully cooked regular soybeans.
Cooked soybeans should be checked periodically for anti-growth factor activity. Use tests that indirectly assess this activity. For information on how to obtain an on-farm test, contact LSB Products, 731 McCall Road, Manhattan, Kansas 66502. Producers also can submit cooked soybeans to a commercial laboratory for a urease test.
Generally a urease level of .20 to .05 pH unit change is indicative of proper cooking. Urease levels greater than .20 pH unit change indicate undercooking and a pH change of less than .05 unit may indicate overcooking. A urease test at a commercial laboratory costs $12 to $15 per sample. As a guide, test every third batch of cooked soybeans. See NebGuide 88-892, Mixing Quality Pig Feed, for details on sampling procedures and laboratory locations.
