[QUOTE="Agriland RSS, post: 7463641, member: 105608"] [img]https://s3-eu-west-1.amazonaws.com/files.thefarmingforum.co.uk/images/agrilanduk.JPG[/img] Written by William Kellett With lamb prices trending well ahead of last year and 78p/kg above the five-year average, UK sheep producers are being encouraged to protect valuable young lambs from preventable disease threats this spring. MSD animal health livestock veterinary adviser Dr. Kat Baxter-Smith said: “This passive immunity then starts to wear off after three weeks, leaving many lambs vulnerable to a variety of infections.” Unnecessary losses from clostridial diseases, such as pulpy kidney or from pasteurellosis, are a particular cause for concern with young lambs during the spring and early summer. According to data from Farm Post Mortems Ltd., there is often a large peak of pulpy kidney in the spring when lambs aged between two and eight-weeks-of-age are affected. On further investigation, in almost all the cases, neither the dams nor their offspring have been protected by vaccination. [SIZE=5][B]Vaccination is strongly advised[/B][/SIZE] Dr Baxter-Smith says that it is impossible to control the multiple and varied stress-related ‘trigger’ factors (e.g. a sudden change in the weather, alteration in diet or parasite infection) for clostridial diseases and other common infections, such as pasteurellosis, so vaccination of young lambs from three-weeks-of-age is strongly advised. She pointed out that coccidiosis is another key disease in lambs that is often triggered by stressful events. This is because any maternally-derived immunity (gained from ewe colostrum) to this particular infection is known to wane at four to six-weeks-of-age. “Oocysts are ingested when lambs lick contaminated objects or ingest feed or water contaminated with faeces. “If coccidiosis has been diagnosed, ask your animal health product supplier about the strategic use of an easy-to-administer, single oral drench alongside sound hygiene practices, which will allow some immunity to develop in your lambs without loss of performance or disease,” she advised. [SIZE=5][B]Orf control[/B][/SIZE] On sheep units with a history of orf, Dr. Baxter-Smith says that young lambs should always be protected from this parapox virus. “Orf-affected lambs have been shown to be 2.2kg lighter on average at finishing, than disease-free animals. “Orf is also a zoonotic virus that can infect humans to cause painful sores on the skin. “Consequently, it’s well worth discussing a flock vaccination protocol with your vet, certainly if you have seen orf in your flock before,” Dr. Baxter-Smith advised.
