Abstract
Se plantea como objetivo describir un patrón de evaluación sistemática de la deformación del borde
dorsal del cuello en burros. Fueron estudiados 25 burros (Eqqus africanus asinus), de raza Andaluza. En relación
al sexo 15 machos (castrados) y 10 hembras, con edades comprendidas entre 12-20 años, en Extremadura,
España. Se practicó un examen clínico y morfológico considerando condición corporal peso y se midió
el perímetro cervical. Se evidenció deformación del borde dorsal del cuello en todos los casos estudiados.
Estos ejemplares presentaron muerte por diversas causas 15 por síndrome metabólico (hiperlipemia) y 10
por accidentes gastrointestinales (Cólico) y se le practicó necropsia y toma de muestras de la región dorsal
del cuello. El estudio morfológico de la deformación del borde dorsal del cuello considerando la cresta de la
nuca (puntuación del 1 al 5) evidencio: para las Puntuaciones: 0,1,2,3.- ningún burro bajo estas categorías.
Puntuación 4.- (56%) y Puntuación 5.- (44%), respectivamente. Los resultados estadísticos del peso versus
el perímetro cervical del cuello presentaron un coeficiente de correlación de 0.8454. Histológicamente la
Puntuación 4.- presentaron vacuolas de grasa abundantes en el espacio intermiofibrilar con tendencia a la
coalescencia, infiltración grasa en tejido muscular, así como un predominio de células adiposas maduras
(lipomatosis marcada) (H&E 40X).Puntuación 5.-se evidenciaron vacuolas de grasa, y abundantes células
adiposas maduras entre las fibras musculares (lipomatosis severa) (H&E 40X). En conclusión se describe
la evaluación sistemática de la deformación del borde dorsal del cuello en burros de raza Andaluza, con sus
patrones morfológicos y macroscópicos e histológicos
ABSTRACT: The aim of this study was to describe a pattern of systematic evaluation of the deformation of dorsal cresty neck in donkeys. We studied 25 donkeys (Equus africanus asinus) of Andalusian breed, in Extremadura Spain. Where are 15 male and 10 females and aged 12-20 years old. Clinical and morphological examination was performed considering weight and body condition cervical circumference was measured. Deformations of the dorsal cresty neck in all cases studied were showed. These specimens had death from various causes 15 for metabolic syndrome (hyperlipidemia) and 10 gastrointestinal injuries and underwent necropsy and sampling of the dorsal neck region. The morphological study of the deformation of the dorsal neck was to (score of 1 to 5) evidenced: any donkey under these for Score: 0, 1,2,3. All donkeys presented cresty neck Score 4 (56%) and Score 5 (44%). The statistical results of weight versus cervical neck circumference showed a correlation coefficient 0.8454. Scoring 4 histological were observed abundant fat vacuoles present in the space intermyofibrillar tendency to coalesce, fatty infiltration in muscle tissue and a predominance of mature fat cells (labeled lipomatosis) (H & E 40X). Score 5 is evidenced fat vacuoles and abundant mature fat cells between the muscle fibers (severe lipomatosis) (H & E 40x). In conclusion were report the systematic evaluation of the deformation of the dorsal cresty neck in donkeys of Andalusian breed with their morphological and macroscopic and histological patterns described.
