    Abstract:

    A total of 296 mixed-sex pigs (PIC 327 × 1050; 14.5 ± 3.0 lb BW and 21 d of age) were used in a 31-d experiment evaluating the effect of further processing methods for Soybean Meal on weanling pig growth performance. There were 11 replicate pens per treatment with 6 or 7 pigs per pen. At weaning, pigs were allotted to pens by initial weight to 1 of 4 treatments in a completely randomized design. Experimental treatments were: (1) negative control (NC: no specialty protein sources), (2) fermented Soybean Meal processing method 1 (FSBM 1), (3) fermented Soybean Meal processing method 2 (FSBM 2), and (4) enzymatically treated Soybean Meal (ETS). The specialty Soybean Meal protein sources were included in Phase 1 (d 0 to 7) and Phase 2 (d 7 to 20) diets at 5%, and diets were formulated to the same standardized ileal digestible (SID) amino acid level. All pigs were subsequently fed a common diet during Phase 3 (d 20 to 31). Phase 1 and 2 diets were fed in pellet form, whereas the Phase 3 common diet was fed in Meal form. Nutrient analyses of specialty Soybean Meal ingredients were conducted and generally matched those used for diet formulation. From d 0 to 7, pigs fed FSBM 2 had increased (P < 0.05) ADG and BW compared with pigs fed ETS, whereas those fed NC and FSBM 1 were intermediate. No other differences were observed between treatments for growth or BW during the experimental period, common period, or overall. In summary, further processed Soybean Meal sources did not improve nursery pig growth compared with traditional Soybean Meal.

    Abstract:

    : We used 360 nursery pigs (35 +/- 3 d of age) in two 21-d growth assays to determine the effects of Soybean Meal particle size on growth performance. In both trials, there were six pigs per pen and 10 pens per treatment. Pigs were weaned on d 21 and fed the same phase I diet for 7 d after weaning, followed by a phase II diet from d 7 to 14. On d 14, all pigs were weighed and randomly allotted to one of three dietary treatments. Experimental diets contained 61.9% corn, 34.4% Soybean Meal, and 3.7% vitamins and minerals. In Exp. 1, 90 barrows and 90 gilts (9.2 +/- 2.3 kg BW) were fed diets containing extruded-expelled Soybean Meal ground to 965, 742, or 639 microm, which resulted in whole-diet particle sizes of 728, 719, and 697 microm, respectively. Reducing extruded-expelled Soybean Meal particle size from 965 or 742 to 639 microm in the diet did not affect (P > 0.10) ADG (541, 538, and 542 g/d), ADFI (886, 875, and 855 g/d; as-fed basis), or gain:feed ratio (0.61, 0.61, 0.64), respectively. In Exp. 2, 90 barrows and 90 gilts (9.9 +/- 2.6 kg BW) were fed diets containing solvent-extracted Soybean Meal ground to 1,226, 797, or 444 microm, which resulted in whole-diet particle sizes of 732, 681, and 629 microns, respectively. Like Exp. 1, reducing particle size of solvent-extracted Soybean Meal did not affect (P > 0.10) ADG (482, 487, and 484 g/d), ADFI (738, 742, and 736 g/d; as-fed), or gain:feed (0.65, 0.65, and 0.65). Reducing particle size of extruded-expelled Soybean Meal or solvent-extracted Soybean Meal increased the angle of repose (maximum degree at which a pile of material retains its slope), indicating that as particle size decreased, flowability characteristics decreased. However, the angle of repose of the complete diets was greater than that for the Soybean Meals, which indicates that decreasing the particle size of Soybean Meal had minimal effects on flow characteristics of the complete diet. Previous research has shown that decreasing grain particle size improves digestibility and feed efficiency, and decreased Soybean Meal particle size has resulted in improved amino acid digestibility. However, the results of our experiments suggest decreasing particle size of either extruded-expelled Soybean Meal or solvent-extracted Soybean Meal does not affect nursery pig growth performance.

    Abstract:

    Summary A total of 350 weanling pigs (initially 15.7 lb) were used to evaluate the effects of Soybean Meal source and level on growth performance of early weaned pigs. Dietary treatments included a control diet containing no Soybean Meal, or diets containing 20% or 40% of either solvent extracted Soybean Meal (SBM) or extruded-expelled Soybean Meal (EESOY). The SBM and EESOY were analyzed for trypsin inhibitor (0.7 mg TI/g and 1.8 mg TI/g, respectively) to ensure quality, and actual crude protein values (46.9% and 48.3% as-fed, respectively) were used in diet formulation. From d 0 to 14, increasing EESOY decreased ADG and ADFI (linear, P 0.05) were found between Soybean Meal sources throughout the trial. The results of this study suggest extrudedexpelled Soybean Meal processed properly and fed in diets immediately after weaning did not improve growth performance of nursery pigs relative to conventional solvent extracted Soybean Meal. When EESOY or SBM was included at 40% in diets fed immediately after weaning, growth performance of weanling pigs was poorer than if fed at lower levels (20%). Feeding properly processed EESOY resulted in similar growth performance compared to feeding SBM.

    Abstract:

    : We used 360 nursery pigs (35 +/- 3 d of age) in two 21-d growth assays to determine the effects of Soybean Meal particle size on growth performance. In both trials, there were six pigs per pen and 10 pens per treatment. Pigs were weaned on d 21 and fed the same phase I diet for 7 d after weaning, followed by a phase II diet from d 7 to 14. On d 14, all pigs were weighed and randomly allotted to one of three dietary treatments. Experimental diets contained 61.9% corn, 34.4% Soybean Meal, and 3.7% vitamins and minerals. In Exp. 1, 90 barrows and 90 gilts (9.2 +/- 2.3 kg BW) were fed diets containing extruded-expelled Soybean Meal ground to 965, 742, or 639 microm, which resulted in whole-diet particle sizes of 728, 719, and 697 microm, respectively. Reducing extruded-expelled Soybean Meal particle size from 965 or 742 to 639 microm in the diet did not affect (P > 0.10) ADG (541, 538, and 542 g/d), ADFI (886, 875, and 855 g/d; as-fed basis), or gain:feed ratio (0.61, 0.61, 0.64), respectively. In Exp. 2, 90 barrows and 90 gilts (9.9 +/- 2.6 kg BW) were fed diets containing solvent-extracted Soybean Meal ground to 1,226, 797, or 444 microm, which resulted in whole-diet particle sizes of 732, 681, and 629 microns, respectively. Like Exp. 1, reducing particle size of solvent-extracted Soybean Meal did not affect (P > 0.10) ADG (482, 487, and 484 g/d), ADFI (738, 742, and 736 g/d; as-fed), or gain:feed (0.65, 0.65, and 0.65). Reducing particle size of extruded-expelled Soybean Meal or solvent-extracted Soybean Meal increased the angle of repose (maximum degree at which a pile of material retains its slope), indicating that as particle size decreased, flowability characteristics decreased. However, the angle of repose of the complete diets was greater than that for the Soybean Meals, which indicates that decreasing the particle size of Soybean Meal had minimal effects on flow characteristics of the complete diet. Previous research has shown that decreasing grain particle size improves digestibility and feed efficiency, and decreased Soybean Meal particle size has resulted in improved amino acid digestibility. However, the results of our experiments suggest decreasing particle size of either extruded-expelled Soybean Meal or solvent-extracted Soybean Meal does not affect nursery pig growth performance.

    Abstract:

    A total of 525 weanling pigs (initially 13.0 lb) were used in two experiments to evaluate the effects of Soybean Meal source and level on growth performance of early weaned pigs. In both experiments, dietary treatments included a control diet containing no Soybean Meal, or diets containing 20% or 40% of either solvent extracted Soybean Meal (SBM) or extruded-expelled Soybean Meal (EESoy). In Exp. 1, diets were formulated with NRC (1998) nutrient values for the solvent extracted Soybean Meal and previously determined values (1998 KSU Swine Day Report of Progress) for the extruded-expelled Soybean Meal. In Exp. 1, from d 0 to 7, increasing solvent extracted Soybean Meal or extrudedexpelled Soybean Meal decreased (linear, P
