Abstract
The objective of this study was to investigate the genetic polymorphisms and transcript levels of
antioxidant and metabolic markers for diarrhea monitoring in Holstein dairy calves. For DNA and
RNA extraction, blood samples were taken from 100 female calves (50 with diarrhea and 50
appearing healthy). DNA sequencing and real time PCR for and metabolic genes were
performed to identify genetic variants linked to diarrhea susceptibility. Results revealed that
there were nucleotide sequence variations in the investigated genes between healthy and
diarrheal calves. Keap1, HMOX1, CMPK2, ASPG, FPGT, TNNI3 K, and LPCAT1 were considerably
more highly expressed in diarrheic calves than resistant ones. The Nrf2, PRDX2, and PRDX6
genes, however, produced a different pattern. This study provides a practical control strategy to
lessen newborn diarrhea in Holstein dairy calves and emphasizes the significance of nucleotide
variations along with antioxidant and metabolic gene expression patterns as proxy markers of
diarrhea susceptibility/resistance.
