The effects of passive immunization against somatostatin on retention time of marker have been investigated in sheep using Cr2O3 as a marker. The mean transit time for clearance of 50% of the marker was significantly retarded in all the anti-somatostatin-treated animals by approximately 19.0 h, as compared with control lambs given a nonspecific antiserum. The findings suggest an important role for circulating somatostatin in the regulation of the rate of flow of digesta through the gastrointestinal tract in lambs. Moreover, it enhances the claim of the immunological approach as a new technique to investigate factors controlling food utilization in farm livestock.
在绵羊中，以三氧化二铬作为标记物，研究了抗生长抑素被动免疫对标记物停留时间的影响。与给予非特异性抗血清的对照羔羊相比，所有接受抗生长抑素治疗的动物清除50%标记物的平均转运时间显著延迟了约19.0小时。这些发现表明，循环生长抑素在调节羔羊消化道食糜流速中起重要作用。此外，这增强了免疫方法作为一种研究控制农场家畜食物利用因素的新技术的可信度。
