The incidence of bovine psorop- tic mange is increasing. In the first half of the 20th century psoroptic mange was the UK’s most com- mon form. The prevalence of par- asites then decreased to very low levels before re-emerging in 2007. Thomas Tiley, professional services vet at Novartis, says the increase in psoroptic mange is hugely significant, is something the industry is not fully aware of yet and correct diagnosis followed by rapid treatment is vital. “Psoroptic mange is caused by the psoroptes mite, a species sim- ilar to the mite which causes s heep scab. It is mainly found along the back, shoulders and tail head of cattle, causing severe dermatitis, scabs and itching,”says Mr Tiley.

He says the disease, which is common in parts of continental Europe,hasrecentlybeenreport- ed in the south west of England. “This is a clear indication the disease is spreading. More alarm- ing still is the fact this particular strain of psoroptic mange is seem- ingly caused by a resistant mite which is proving more difficult to treat than the other types. “Mange is mainly a problem in winter and early spring, and with the entire lifecycle taking place on the host, transmission is usually by direct contact be- tween cattle. Treatments include injectable and pour-on 3-ML productsand permethrin- based pour ons.” Lice Lice are common in cattle and are also spread by direct contact. Bit- ing lice are most common, affect- ing the neck, shoulders and rump. Sucking lice will pierce the skin of cattle and suck blood; in large numbers this can cause anaemia. “Using a treatment for both lice and mange control ensures com- plete peace of mind, ” says Miss Langham. “A licensed treatment used repeatedly at four weekly in- tervals is recommended and farm- ers should consult their veterinary surgeon for diagnosis and speak to a vet for the most appropriate treatmentoptions. “All cattle should be treated on the farm, at the same time if pos- sible, and dosing guidelines should be accurately followed; under-dos- ing can also lead to the develop- ment of treatment-resistant lice. ” Fluke Another key parasite of impor- tance at this time of year is liver fluke. Mr Tilley says it is especially important for beef farmers to be aware of fluke, as production loss- es can occur without noticeable symptoms. He also stresses the im- portance of using a product which will kill the stages of fluke present at the time. “If you use a product which kills adults only, you may need to wait up to 10 weeks after housing before the immature fluke have developed into adults and suscep- tible to treatment. “Any cattle infected with fluke will suffer production losses dur- ing this 10-week period; at housing time, it is therefore advisable to use a triclabendazole product which kills all three stages of fluke in one dose.” For mixed farms he advises con- sidering dual species flukicides. ■Mange – All mites cause irritation, thickened scaly skin and hair loss.

Farmers need to ensurethey have a robustwinter parasite controlprogramme in place.This was the message
from leading UK veterinary par-asitologists during a series of meetings organised by NovartisAnimal Health.
Helen Langham, Novartisproduct manager, says: “Ectopar-asites, whose lifecycles are suitedto the close contact of housed beef cattle, and in particular the re-emergence of a more severe formof mange known as psoroptic
mange, can affect profitability.“Farmers should be alert to thesymptoms and recommendedtreatments for these parasites aswe enter the winter period andalso be aware of the potentially se-rious problem of the endoparasiteliver fluke.”
MangeMiss Langham says mange,caused by mites, has three maintypes; chorioptic, sarcoptic andpsoroptic mange (see panel).
The incidence of bovine psorop-tic mange is increasing. In the firsthalf of the 20th century psoropticmange was the UK’s most com-mon form. The prevalence of par-asites then decreased to very lowlevels before re-emerging in 2007.
