eBEEF.org Monday: Genetic Markers of Bovine Respiratory Disease Complex (BRDC) Susceptibility

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.
