96 Effects of Soybean Meal Inclusion Rate on Growth Performance of 40- to 90-kg Pigs

Abstract An experiment was conducted to determine the effects of soybean meal (SBM) inclusion rate on growth performance growing pigs. A total 1,722 pigs (initial BW = 41.1 kg), placed in pens with 20 or 21 each, were used a 49-d trial. There 2 treatments consisting different SBM rates. Experimental diets fed 3 phases. Treatment 1 (low SBM) contained 18, 14, and 12% (high 26, 22, 19% phases 1, 2, 3, respectively. The levels obtained by adjusting synthetic amino acids. Both formulated same SID Lys (1.00, 0.92, 0.85% respectively) net energy (2,565, 2,575, 2,581 kcal/kg respectively). diet formulation equivalent 90% corn energy. 42 replicates per treatment. Pigs weighed approximately every weeks calculate ADG, ADFI, G:F, caloric efficiency. Data analyzed SAS MIXED procedure. Overall (d 0 49), there no evidence for differences (P > 0.10) final BW. high had improved < 0.01) G:F removal mortality 1.05% (9 pigs) low treatment 0.46% (4 In conclusion, increasing resulted efficiency
