In 2 experiments, 602 pigs were used to evaluate the effects of fish meal, fermented soybean meal, or dried porcine solubles on phase 2 nursery pig performance. In Exp. 1, nursery pigs (n = 252; PIC TR4 x 1050; 6.8 kg initial BW and 7 d after weaning) were fed: 1) a control diet containing no specialty protein sources and the control diet with 2) 5% fish meal, 3) 3.5% dried porcine solubles, 4) 6.0% fermented soybean meal, 5) a combination of 1.75% fermented soybean meal and 1.75% dried porcine solubles, or 6) a combination of 3.0% fermented soybean meal and 2.5% fish meal. There were 7 replications with 6 pigs per pen. Experimental diets were fed for 14 d, and then all pigs were fed a common diet without specialty protein sources for 14 d. From d 0 to 14, pigs fed dried porcine solubles alone or with fermented soybean meal had improved (P < 0.05) ADG and G:F compared with pigs fed all other diets. Overall (d 0 to 28), pigs fed dried porcine solubles had improved (P = 0.01) ADG (421 vs. 383 g) and G:F (0.77 vs. 0.73) compared with pigs fed the control diet and had improved (P = 0.03) G:F (0.77 vs. 0.74) compared with pigs fed the combination of fermented soybean meal and fish meal. In Exp. 2, nursery pigs (n = 350; PIC C22 x 1050; 6.1 kg initial BW and 7 d after weaning) were fed 1) a control diet containing no specialty protein sources and the control diet with 2) 3% fish meal, 3) 6% fish meal, 4) 3.75% fermented soybean meal, 5) 7.50% fermented soybean meal, 6) a combination of 1.88% fermented soybean meal and 1.88% dried porcine solubles, or 7) a combination of 3.75% fermented soybean meal and 3.75% dried porcine solubles. There were 10 replications with 5 pigs per pen. Experimental diets were fed from d 0 to 14, and then all pigs were fed a common diet without specialty protein sources for 21 d. From d 0 to 14, pigs fed increasing fish meal had increased (quadratic, P = 0.05) ADFI. Pigs fed increasing fermented soybean meal had improved (quadratic, P = 0.01) G:F. Pigs fed the combination of fermented soybean meal and dried porcine solubles had improved (P < 0.05) ADG and G:F compared with pigs fed diets containing fish meal and had improved (P < 0.05) ADG and ADFI compared with pigs fed diets containing fermented soybean meal. Overall (d 0 to 35), pigs fed diets with increasing amounts of fermented soybean meal had improved (quadratic, P = 0.03) G:F. Feeding nursery pigs diets containing dried porcine solubles, either alone or in combination with fermented soybean meal, can improve growth performance compared with those fed high concentrations of soybean meal or fish meal.
在 2 项实验中，使用了 602 头猪来评估鱼粉、发酵豆粕或干猪可溶性蛋白对 2 阶段仔猪性能的影响。在实验 1 中，仔猪（n = 252； PIC TR4 x 1050；初始体重 6.8 千克，断奶后 7 天）饲喂：1）不含特殊蛋白质来源的对照日粮和 2）5%鱼粉、3）3.5%干猪可溶性蛋白、4）6.0%发酵豆粕、5）1.75%发酵豆粕和 1.75%干猪可溶性蛋白的组合、6）3.0%发酵豆粕和 2.5%鱼粉的组合。有 7 个重复，每个猪圈有 6 头猪。实验日粮饲喂 14 天，然后所有仔猪饲喂不含特殊蛋白质来源的普通日粮 14 天。从第 0 天到第 14 天，单独或与发酵豆粕一起饲喂干猪可溶性蛋白的仔猪 ADG 和 G:F 提高（P < 0.05），与饲喂其他所有日粮的仔猪相比。总体上（第 0 天到第 28 天），与饲喂对照日粮的仔猪相比，饲喂干猪可溶性蛋白的仔猪 ADG（421 比 383 g）和 G:F（0.77 比 0.73）提高（P = 0.01），与饲喂发酵豆粕和鱼粉组合的仔猪相比，G:F（0.77 比 0.74）提高（P = 0.03）。在实验 2 中，仔猪（n = 350； PIC C22 x 1050；初始体重 6.1 千克，断奶后 7 天）饲喂：1）不含特殊蛋白质来源的对照日粮和 2）3%鱼粉、3）6%鱼粉、4）3.75%发酵豆粕、5）7.50%发酵豆粕、6）1.88%发酵豆粕和 1.88%干猪可溶性蛋白的组合、7）3.75%发酵豆粕和 3.75%干猪可溶性蛋白的组合。每个猪圈有 10 个重复，每个猪圈有 5 头猪。实验日粮从第 0 天到第 14 天饲喂，然后所有仔猪饲喂不含特殊蛋白质来源的普通日粮 21 天。从第 0 天到第 14 天，饲喂鱼粉的仔猪 ADFI 增加（二次，P = 0.05）。饲喂发酵豆粕的仔猪 G:F 提高（二次，P = 0.01）。与饲喂含鱼粉日粮的仔猪相比，饲喂发酵豆粕和干猪可溶性蛋白组合的仔猪 ADG 和 G:F 提高（P < 0.05），与饲喂发酵豆粕日粮的仔猪相比，ADG 和 ADFI 提高（P < 0.05）。总体上（第 0 天到第 35 天），饲喂发酵豆粕日粮的仔猪 G:F 提高（二次，P = 0.03）。与饲喂高浓度豆粕或鱼粉日粮的仔猪相比，饲喂含有干猪可溶性蛋白的日粮或与发酵豆粕组合的日粮可以提高仔猪的生长性能。
