A review was done with 25 scientific papers published in the past fifteen years with the objective to verify the effects of spray dried plasma added to diets for pigs weaned at different ages on the feed intake, weight gain, intestinal structure, and number of E. coli colonies. Beneficial effects of spray dried plasma were observed during the first week after weaning for weight gain and feed intake of piglets weaned at 14, 21, and 28 days old. The beneficial effects of spray dried plasma decreased with the increase in weaning age. Positive effects of spray dried plasma were observed on the morph-physiological conditions of the small intestine, with higher villi height and crypt depth, when substituted completely for the powdered skim milk in diets for weaned pigs. Also, pigs fed diets with the inclusion of spray dried plasma had decreased E. coli colonies in the small intestine of pigs weaned at 21, 28, and 35 days old. The research also indicated that spray dried plasma can replace antibiotic in diets to pigs weaned at 28 and 35 days old. The article presents some promising patents on feed intake for pigs weaned at different ages.
对过去十五年发表的25篇科学论文进行了综述，目的是验证添加到不同年龄断奶仔猪日粮中的喷雾干燥血浆对采食量、体重增加、肠道结构和大肠杆菌菌落数的影响。在断奶后第一周，观察到喷雾干燥血浆对14日龄、21日龄和28日龄断奶仔猪的体重增加和采食量有有益影响。喷雾干燥血浆的有益效果随着断奶年龄的增加而降低。当完全替代断奶仔猪日粮中的脱脂奶粉时，观察到喷雾干燥血浆对小肠的形态生理状况有积极影响，绒毛高度和隐窝深度更高。此外，在21日龄、28日龄和35日龄断奶仔猪的日粮中添加喷雾干燥血浆，小肠中的大肠杆菌菌落数减少。研究还表明，喷雾干燥血浆可以替代28日龄和35日龄断奶仔猪日粮中的抗生素。本文介绍了一些关于不同年龄断奶仔猪采食量的有前景的专利。
