With lamb prices buoyant, sheep producers are being urged to realise full value for the 2010 crop by making sure finishing lambs on the farm are vaccinated against pasteurellosis and the main clostridial diseases. 2010 lambs will remain vulnerable to pasteurella and clostridial diseases unless they are vaccinated from three weeks of age.“Losing lambs to easily preventable diseases this summer really is throwing money away,” says Intervet/Schering-Plough Animal Health ruminant veterinary adviser Drew McGurren MRCVS. He explains that the colostrum lambs receive from the ewe shortly after birth only gives them protection for a limited time against pasteurellosis and diseases like pulpy kidney, braxy, blackleg and tetanus. “It’s true that if ewes are vaccinated properly with Heptavac-P Plus in the run up to lambing then the lambs will also gain immunity.
