The aim of this study was to describe the morphological,
histological and immunohistochemical changes in muscle
biopsies in equines with dorsal neck deformation. They were
studied 150 horses of the races: Spanish Pure Breed Spanish
(84/150), Arabic-Hispanic (33/150), Lusitano (19/150), Cross
(14/150), between 5-15 years, all with DBDC, in the Autonomous
Communities of Andalucia and Extremadura, Spain. A clinical and
morphological examination was performed on each equine. The
biopsy technique was performed on the dorsal neck region. The
tissue fragments were processed by conventional histological
methods and were classified by histological recognition patterns;
the Desmina antibody was used for the immunohistochemical
study. An ANOVA statistical analysis was performed, as well as a
covariance analysis of the studied variables. The results showed
DBDC (cresty neck) in all equines studied, with predominance
of neck deformation grade 3 (67%), grade 4 (25%) and grade 5 (8%). Desmin antibody was negative for grades of neck deformity
3, 4 and 5 (Negative Desmin ---). The statistical results show a
negative correlation between the degree of deformity and the
morphometric measurements of the biopsy (-0.71), as well as in
the rest of the studied variables. In conclusion, the morphological
changes observed were degenerative metabolic processes
associated with fat infiltration, these changes were observed in
the muscular myofibril characterized by increased intercellular
space, cellular cytoskeletal loss and loss of Z bands, associated
with fat infiltration (lipomatosis), in the equine studied.
