Background:

Liver biopsies are crucial for assessing animal health and nutritional status.
Monitoring key biomarkers like copper and vitamin E is essential for livestock management.

Purpose of the Study:

To evaluate the feasibility and methodology of serial liver biopsies in sheep.
To establish baseline levels and monitor changes in liver copper and vitamin E concentrations over time.

Main Methods:

Performed serial liver biopsies on 16 sheep over 8 consecutive weeks.
Utilized specialized equipment including a fiber optic light source and telescope.
Collected approximately 300 mg of liver tissue per biopsy for analysis.

Main Results:

Successfully obtained serial liver biopsy samples from all sheep.
Established a repeatable procedure for liver sampling in ovine subjects.
Quantified liver copper and vitamin E levels for subsequent analysis.

Conclusions:

Serial liver biopsies are a viable method for monitoring ovine nutritional status.
The collected data will inform nutritional management strategies for sheep.
Further analysis will elucidate the dynamics of copper and vitamin E in sheep livers.
