Are biochemical variables from Holstein-Friesian calves older than one week comparable to those obtained from adult animals of stable metabolic status on the same farm?
With the exception of AST and GGT activity, RI for standard biochemistry variables determined for adult cattle are likely to be valid for calves older than one week. However, special consideration is necessary for calves within their first week of life.
While the clinical similarities between Blau Syndrome and sarcoidosis suggest genetic homogeneity between the disorders, we found no evidence for linkage of sarcoidosis to the Blau syndrome locus. Our exclusion results suggest that the Blau Syndrome gene does not have a major effect on sarcoidosis susceptibility.
