Hi
This is the first time we have had sheep to breed, previously just fattened up store lambs.
I know that we need to give the heptavac-P 4 weeks before lambing and that if they have not been vaccinated before the sheep need 2 doses 4-6 weeks apart. Is it too late to give the 2 initial injections now if sheep due to lamb beginning of March? Also we have 10 ewes that we do not know if they have had the initial injection, will it harm to do again or should we just give them the 1 injection before lambing?
Any help appreciated!
