Spastic paresis (cattle)
Spastic paresis is a congenital disorder of cattle.
It is due to contraction of gastrocnemius muscle, which develops within the first 6 months of life.[1]
It can be unilateral or bilateral.
-
right limb stretched beforehand
-
special stance of same affected calve
-
asymmetric back (compensatory development of left side muscles)
-
bilateral, in a one-year-old heifer
Treatment
Treatment by partial tenotomy of insertions of the gastrocnemius muscle and the calcanean tendon sheath (hock joint) has been abandoned.
Neurectomy of gastrocnemius muscle nerves demands strong retractors, nerve electric stimulators (to avoid section of sensitive branches) and good knowledge of limb innervation.
