Я бы не сказала, что статья в целом неправильная. Как, в общем-то, характерно для такого рода статей, надергана информация из международных источников и подана под таким соусом, что непосвященному в проблему человеку в глаза бросаются не причины под цифрами, а одна-две строки из раздела "конюшенный менеджмент", а именно "никогда не держите лошадь запертой в деннике". Так и хочется перефразировать - никогда не запирайте денник!
Фраза о том, что "мышечные проблемы, связанные с работой лошади, – распространенное явление, и до сих пор никто не может понять, почему это случается. Однако очевидно, что в природе лошади им не страдают", - вот это чистой воды популистика, не имеющая ничего общего с действительностью. Во всех мало-мальски надежных ветеринарных источниках указаны и причины, и то, что миоглобинурия бывает пастбищной, она во всем мире называется атипичная миоглобинурия. Автор либо "не дочитал", либо умышленно "не доперевел", подредактировал.
Согласно приведенным ниже выдержкам, я не могу согласиться с этой фразой:
http://www.merckvetmanual.com/mvm/index ... /91008.htm
The most common cause of sporadic tying-up is exercise that exceeds the horse’s underlying state of training. The incidence of muscle stiffness also has increased during an outbreak of respiratory disease. Deficiencies of sodium, calcium, vitamin E, or selenium in the diet may also be contributory factors. - Почему же в КМ пишут, что никто не может понять, хотя в manual написано, почему это бывает???
AAEP
Exertional rhabdomyolysis (ER) has been recognized in horses for more than 100 years as a syndrome of muscle pain and cramping associated with exercise. Recently it has been recognized that this syndrome has numerous possible causes. Sporadic forms of ER are due to over-training and muscle strain, dietary deficiencies of electrolytes, vitamin E and selenium or exercise in conjunction with herpes or influenza virus infections. Chronic forms are due to specific inherited abnormalities such as polysaccharide storage myopathy (PSSM) in Quarter Horses, Warmbloods and Draft breeds or recurrent exertional rhabdomyolysis (RER) in Thoroughbreds, Standardbreds and Arabians.
Causes of Atypical Myoglobinuria (т.е. ПРИЧИНЫ):
Associated with a sudden deterioration in weather conditions
Thought to be connected with a toxic fungal overgrowth that flourishes in foul weather.
Not protecting susceptible horses by providing shelter from bad weather
Not ensuring horses have supplementary feed, such as plenty of hay, while out at grass.
Not ensuring general good health and well-being
Not worming or taking care of infestation
Equine Atypical Myopathy
Posted on November 17, 2009 by admin
A recent letter in one of our vet journals caught my eye and would be interesting to many of our clients.
We would like to alert practitioners that there has been an extremely high prevalence of equine atypical myopathy this autumn. During October an unusually high number of cases was observed in southern England and throughout northern Europe.
Equine atypical myopathy affects individuals and groups of horses at pasture and has high mortality. Young horses in poor to normal body condition are particularly prone to the condition and risk factors include cold, damp, frost-free weather and pastures with poor natural drainage and vegetation of low nutritional value.
Affected horses have discoloured brown urine and are stiff and weak, progressing to recumbency. In its early stages, the condition can be confused with colic or laminitis. Serum activities of creatine kinase and aspartate transaminase and urine myoglobin concentrations are markedly increased. Intensive supportive care is indicated.
For more information on preventive measures, and to report suspected cases, please go to www. myopathieatypique.be the website is in English and Frency
Note I have seen cases of this condition in Durham and Northumberland, all survived but were very ill for some time.
