Summary
Adding single-cell bacterial protein to pig feed positively impacted liver thiamine content. However, higher protein levels reduced thiamine absorption in the jejunum, causing villi changes.
Area of Science:
- Animal Nutrition
- Biochemistry
- Histology
Background:
- Single-cell protein (SCP) is a potential feed supplement for livestock.
- Thiamine (vitamin B1) is essential for animal metabolism.
- Understanding SCP's impact on nutrient metabolism and gut health is crucial.
Purpose of the Study:
- To evaluate the effect of dietary single-cell bacterial protein on thiamine metabolism in pigs.
- To assess the histological changes in the jejunum and liver of pigs fed SCP.
Main Methods:
- 21 hybrid Camborough pigs were divided into three groups: control, 4% SCP, and 8% SCP.
- Pigs were observed up to 90 days.
- Liver thiamine content, jejunal 35S-thiamine incorporation, and histological examinations were performed.
Main Results:
- Dietary SCP increased total thiamine content in the liver.
- 8% SCP inclusion reduced 35S-thiamine incorporation in the jejunum.
- Histological analysis revealed shortened and thickened intestinal villi and signs of protein dystrophy in liver cells.
Conclusions:
- Single-cell bacterial protein can enhance liver thiamine levels in pigs.
- High levels of SCP may impair thiamine absorption in the jejunum.
- Further research is needed to optimize SCP inclusion rates for pig nutrition.
