What is actually occurring within a sheep with worm resistance? This week on the podcast we have a fascinating discussion with Dr Kelsey Bentley who has spent her career so far looking into the immune mechanisms of Katahdin sheep in the US. Kelsey runs us through what happens biologically within the sheep to make it ‘resistant’. She has also researched the importance of the role of colostrum in lamb immunity. Kelsey explains how it provides essential immunological benefits - particularly through IgG and IgA antibodies - and that colostrum quality varies between sheep and therefore is under genetic influence.
Highlights:
- The make-up of the Katahdin breed
- The biology of parasite resistance
- The genetics of parasite resistance
- The effect of worm resistance on other traits like growth
- The importance of good quality colostrum
- Behavioral responses to illnesses
