Dr. Herman Block advised breeders to routinely vaccinate broilers to protect them against infectious bursal disease (IBD), while addressing a meeting of broiler producers at Shrewsbury, Shropshire, organized by the Slate Hall Veterinary Practice in conjunction with Lohmann Animal Health.
Dr. Block said he found AviPro IBD Xtreme, a vaccine for IBD, induced an earlier and higher sero-response than others. The vaccine, he said, provided protection in disease "hot-spots" and was used on about 60% of the birds.
Brigitte Othmar, product manager, Lohmann Animal Health, said trials showed that birds vaccinated with AviPro IBD Xtreme showed the highest number of sero-positive results and protection against clinical symptoms of IBD.
