Complex diseases such as BRDC involve the
influence of many genes and are by definition hard to predict. Genomic
heritability estimates of BRDC susceptibility in Holstein dairy calves is
moderately heritable (0.21). The Single Nucleotide Polymorphism assays are
finding genomic regions associated with BRDC susceptibility, suggesting that
genetic progress in these traits could be made by including the specific SNP
markers that are indicators of BRDC disease risk in national cattle genetic
evaluations.
