Three growth assays were conducted to determine the efficacy of replacing dried skim milk and(or) dried whey in diets of starting pigs with commercially available spray-dried porcine plasma, spray-dried porcine blood, spray-dried bovine plasma, or spray-dried extracted meat protein. In Exp. 1, 236, 24-d-old crossbred pigs were fed diets containing either skim milk and whey or porcine plasma from 0 to 14 d postweaning and whey or porcine plasma from 14 to 28 d. Although pigs fed diets containing porcine plasma had greater ADFI and ADG than those fed milk products from 0 to 7 d, no differences were observed from d 0 to 14 or from 14 to 28 d postweaning. In Exp. 2, 204, 21-d-old pigs were fed corn-soybean meal-based diets using the following supplemental protein source combinations: skim milk and whey; skim milk, whey, and casein; porcine plasma, whey, and lactose/starch (10%); porcine plasma and lactose/starch (24.4%); or whey. A common diet (1.25% lysine, 10% whey) was fed from 14 to 35 d postweaning. Pigs fed diets containing porcine plasma consumed more feed and had greater ADG than others (P < .05) from 0 to 14 d and from 0 to 35 d. Both ADG and ADFI were highest when the diet contained 10.3% porcine plasma, 20% whey, and 10% added lactose. Experiment 3 used 150, 21-d-old pigs to compare the inclusion of skim milk, porcine plasma, porcine blood, bovine plasma, or meat extract in diets fed from 0 to 14 d postweaning. A common diet (the same as in Exp. 2) was fed from 14 to 35 d. Pigs fed porcine plasma had greater ADFI (P < .05) from 0 to 14 d than pigs fed other treatments. Also, pigs fed porcine plasma had greater ADG (P < .05) from 0 to 14 d than pigs fed all other diets except porcine blood. Pigs fed porcine blood had the largest ADFI (P < .05) from 14 to 35 d compared with pigs fed other diets. These experiments indicate that porcine plasma is a protein supplement superior to skim milk in diets of starting pigs and that porcine blood has a positive influence on subsequent growth performance.
进行了三项生长试验，以确定用市售喷雾干燥猪血浆、喷雾干燥猪血、喷雾干燥牛血浆或喷雾干燥提取肉蛋白替代断奶仔猪日粮中的脱脂奶粉和（或）乳清粉的效果。在试验1中，236头24日龄的杂交仔猪在断奶后0至14天饲喂含脱脂奶粉和乳清粉或猪血浆的日粮，14至28天饲喂含乳清粉或猪血浆的日粮。尽管在0至7天，饲喂含猪血浆日粮的仔猪比饲喂乳制品的仔猪具有更高的平均日采食量（ADFI）和平均日增重（ADG），但在断奶后0至14天或14至28天未观察到差异。在试验2中，204头21日龄仔猪饲喂以玉米-豆粕为基础的日粮，使用以下补充蛋白质源组合：脱脂奶粉和乳清粉；脱脂奶粉、乳清粉和酪蛋白；猪血浆、乳清粉和乳糖/淀粉（10%）；猪血浆和乳糖/淀粉（24.4%）；或乳清粉。在断奶后14至35天饲喂一种通用日粮（赖氨酸1.25%，乳清粉10%）。在0至14天以及0至35天，饲喂含猪血浆日粮的仔猪比其他仔猪采食更多饲料且ADG更高（P<0.05）。当日粮含有10.3%猪血浆、20%乳清粉和10%添加乳糖时，ADG和ADFI均最高。试验3使用150头21日龄仔猪比较在断奶后0至14天饲喂的日粮中添加脱脂奶粉、猪血浆、猪血、牛血浆或肉提取物的效果。在14至35天饲喂一种通用日粮（与试验2相同）。在0至14天，饲喂猪血浆的仔猪比饲喂其他处理日粮的仔猪ADFI更高（P<0.05）。此外，在0至14天，饲喂猪血浆的仔猪比饲喂除猪血外所有其他日粮的仔猪ADG更高（P<0.05）。与饲喂其他日粮的仔猪相比，在14至35天，饲喂猪血的仔猪ADFI最大（P<0.05）。这些试验表明，在断奶仔猪日粮中，猪血浆是一种优于脱脂奶粉的蛋白质补充剂，并且猪血对后续生长性能有积极影响。
