An experiment was carried out with a total of 21 hybrid Camborough pigs divided into three groups--group I, controls; group II, with 4 per cent of single-cell protein in the feed; and group III, with 8 per cent of such protein in the feed. The rations were balanced in terms of the basic feedstuffs. The pigs were kept under observation up to the age of 90 days. Three animals were periodically killed each time for investigation. Studied was the content of the total thiamine in the liver and the incorporation of the labelled 35s-thiamine in the jejunum. A histologic examination was also carried out of the jejunal mucosa and the liver. It was established that the inclusion of single-cell bacterial protein into the ration produced a positive effect on the total thiamine content of the liver. The group that was offered 8 per cent of this protein source showed reduced level of 35s-thiamine incorporation in the jejunum. Histologically, there were shortening and thickening of the intestinal villi along with signs of protein dystrophy in the liver epithelial cells in the case of animals given single-cell bacterial protein with the feed.
用21头杂交坎波猪进行了一项实验，将其分为三组——第一组为对照组；第二组，饲料中含4%的单细胞蛋白；第三组，饲料中含8%的这种蛋白。日粮在基本饲料方面是平衡的。这些猪一直被观察到90日龄。每次定期宰杀3头猪进行研究。研究了肝脏中硫胺素总量以及标记的35S -硫胺素在空肠中的掺入情况。还对空肠黏膜和肝脏进行了组织学检查。结果表明，日粮中添加单细胞细菌蛋白对肝脏硫胺素总量产生了积极影响。提供8%这种蛋白质来源的组，空肠中35S -硫胺素的掺入水平降低。组织学上，给猪喂食含单细胞细菌蛋白的饲料后，肠绒毛缩短变厚，同时肝脏上皮细胞出现蛋白质营养不良的迹象。
