Two experiments were conducted to determine if fermented corn protein (FCP) can serve as a replacement to enzymatically treated soybean meal (ESBM) in 6.0 to 15.8 kg or as a replacement for soybean meal in 12.1 to 24.7 kg pig nursery diets. In Exp. 1, 350 barrows (initially 6.0 kg) were randomly allotted to 5 treatments with 5 pigs/pen and 14 replications/treatment. Dietary treatments were arranged in a 2×2 + 1 factorial with a control diet or diets with 5 or 10% FCP or ESBM. Newly weaned pigs were fed phase 1 diets for 10-d followed by phase 2 diets for 21-d. There were no interactions throughout the experiment. Overall (d 0-31), pigs fed increasing FCP had decreased (linear, P ≤ 0.026) ADG and ADFI with no differences in G:F, whereas increasing ESBM had no effect on growth performance (Table). Pigs fed ESBM had increased (P ≤ 0.034) ADG and G:F compared with pigs fed FCP with no effect on ADFI. In Exp 2, 350 pigs (initially 12.1 kg) were randomly assigned to pens with 5 pigs/pen and 14 replications/treatment. On d 24 after weaning (d 0 of trial), pens of pigs were weighed and assigned to 5 dietary treatments. Dietary treatments were arranged in a 2×2 + 1 factorial with a control diet or diets with 10 or 20% FCP with either high or low Val+Ile:Leu ratios. There were no interactions observed throughout the experiment. Overall (d 0-21), ADG, ADFI, and G:F worsened (linear, P < 0.001) as FCP increased. High Val+Ile:Leu ratios improved (P = 0.017) G:F compared with low Val+Ile:Leu ratios with no effect on ADG and ADFI. In summary, using FCP to replace ESBM for nursery pigs weighing 6.0 to 15.8 kg had decreased growth performance. Increasing concentrations of FCP in diets for pigs weighting 12.1 to 24.7 kg worsened growth and increasing Val+Ile:Leu ratios only improved G:F.

141 发酵玉米蛋白源对保育猪生长性能的评价

进行了两个实验以确定发酵玉米蛋白 (FCP) 是否可以替代 6.0 至 15.8 公斤的酶处理豆粕 (ESBM) 或替代 12.1 至 24.7 公斤的猪保育日粮中的豆粕。在 Exp。1, 350 头公猪（最初 6.0 kg）被随机分配到 5 个处理，每栏 5 头猪和 14 个重复/处理。饮食治疗安排在 2×2 + 1 阶乘中，带有对照饮食或含有 5% 或 10% FCP 或 ESBM 的饮食。新断奶的猪在第 1 阶段饲料喂养 10 天，然后在第 2 阶段饲料喂养 21 天。在整个实验过程中没有相互作用。总体而言（d 0-31），饲喂增加 FCP 的猪降低了（线性，P ≤ 0.026）ADG 和 ADFI，而 G:F 没有差异，而增加 ESBM 对生长性能没有影响（表）。饲喂 ESBM 的猪增加了 (P ≤ 0.034) ADG 和 G：F 与饲喂 FCP 的猪相比，对 ADFI 没有影响。在实验 2 中，350 头猪（最初 12.1 公斤）被随机分配到猪栏，每栏 5 头猪和 14 次重复/处理。在断奶后第 24 天（试验第 0 天），将猪圈称重并分配 5 个日粮处理。饮食治疗以 2×2 + 1 阶乘的方式与对照饮食或具有 10% 或 20% FCP 的饮食以及高或低 Val+Ile:Leu 比率进行安排。在整个实验过程中没有观察到相互作用。总体而言 (d 0-21)，随着 FCP 增加，ADG、ADFI 和 G:F 恶化（线性，P < 0.001）。与对 ADG 和 ADFI 没有影响的低 Val+Ile:Leu 比率相比，高 Val+Ile:Leu 比率改善了 (P = 0.017) G:F。总之，使用 FCP 代替 ESBM 对 6.0 至 15.8 kg 的保育猪生长性能有所下降。
