The Black Baldy is reared for beef. [3]: 256 Cows may be mated to a bull of a European beef breed, to produce a heavier, better-muscled and faster-growing calf. [2]: 190 In Britain and Ireland a similarly-marked cross-breed, the Black Hereford, results from crossing Hereford bulls on predominantly black-coloured dairy cows. [citation needed]
Congenital contractural arachnodactyly (CA), also known as fawn calf syndrome, is an autosomal recessive genetic disorder in cattle. [1] The disorder affects the connective tissue of muscles, [ 1 ] leading to contracture of the upper limb (most obvious in the hind limbs), and laxity of the joints of the lower limbs. [ 2 ]
Early signs: swelling of the thigh, with leg up and tail raised (arrows) Recovered calf after removing of all necrotic tissue. Blackleg, black quarter, quarter evil, or quarter ill (Latin: gangraena emphysematosa) is an infectious bacterial disease most commonly caused by Clostridium chauvoei, a Gram-positive bacterial species.
Benign acute childhood myositis (BACM) is a syndrome characterized by muscle weakness and pain in the lower limbs that develop in children after a recent viral illness. It is transient with a spontaneous clinical resolution within 1 week.
The Black Baldy, found in Australia and North America, is another crossbred beef type, black with white head, derived from a Hereford crossed with an Aberdeen Angus. The American Black Hereford (breed) is a black colour variety of Hereford cattle, originally developed by crossing Hereford and Angus cattle
Bovine progressive degenerative myeloencephalopathy (BPDME), also known as weaver syndrome, is a genetic disorder of cattle, characterized by hindlimb weakness and ataxia. It has been observed in male and female Brown Swiss cattle. It is known as 'weaver syndrome' because of the animals' 'weaving' gait while walking. [1]
Sporadic late-onset nemaline myopathy, or SLONM, is a very rare disease, one of the nemaline myopathies, causing loss of muscle bulk and weakness in the legs but sparing the cranial nerves, and beginning its clinical course after age 40. [1]
A physical exam indicates a lack of pectoral and upper arm muscles, especially when the disease is unnoticed through the early teen years. Muscle wasting begins in the legs and pelvis, and then progresses to the muscles of the shoulders and neck. Calf muscle enlargement (pseudohypertrophy) is quite obvious. Among the exams/tests performed are ...
