Abstract/OtherAbstract:
The objective was to evaluate the association between the single nucleotide polymorphism at position +735 in the interleukin-8 receptor-α (CXCR1) gene (CXCR1c.735) and disease incidence, milk production, reproductive performance, and survival in Holstein cows. Three-hundred fifty Holstein cows were enrolled. No association was found between CXCR1c.735 genotype and retained fetal membranes, metritis, or endometritis. Incidence rate of clinical mastitis was associated with CXCR1c.735 genotype; cows with genotypes CC and GC had a decreased incidence rate of clinical mastitis compared with GG cows. Milk yield was associated with CXCR1c.735 genotype; cows with genotype GC had greater milk yield than GG cows. Hazard of pregnancy was not associated with CXCR1c.735 genotype. Cows that had clinical mastitis had decreased hazard of pregnancy, and cows that had endometritis tended to have a decreased hazard of pregnancy. Hazard of death or culling was not associated with CXCR1c.735 genotype. Multiparous cows and cows that had mastitis had increased hazard of death or culling. In contrast to what we expected, cows with the genotype GG had an increased incidence rate of clinical mastitis and decreased milk yield.
