Background:

Scrapie is a fatal neurodegenerative disease affecting sheep and goats.
The transferrin system plays a role in iron metabolism and has been implicated in disease resistance.
Herdwick sheep are a distinct British breed with unique genetic characteristics.

Purpose of the Study:

To investigate the association between transferrin phenotypes and scrapie susceptibility in Herdwick sheep.
To determine if specific transferrin variants influence disease development in this breed.

Main Methods:

Phenotyping of the transferrin system in a flock of Herdwick sheep.
Experimental induction of scrapie in the studied sheep.
Statistical analysis to correlate transferrin phenotypes with scrapie susceptibility.

Main Results:

No significant correlation was identified between transferrin phenotypes and scrapie susceptibility.
All observed transferrin phenotypes were present in both susceptible and non-susceptible sheep.

Conclusions:

Transferrin phenotypes do not appear to be a significant factor in Herdwick sheep susceptibility to experimentally induced scrapie.
Further research may be needed to explore other genetic or environmental factors influencing scrapie resistance in this breed.
