Article Synopsis
- Johne's disease (JD) is a major infectious disease affecting ruminants like cattle, leading to significant economic losses globally; this study focused on assessing the genetic traits related to JD susceptibility in Holstein cows in the U.S.* -
- Using extensive data from 365,980 Holstein cows, researchers analyzed milk samples to determine JD incidence, which averaged 4.72%, and estimated the heritability of susceptibility to JD with varying results depending on the models used.* -
- The findings revealed a negative genetic trend for JD susceptibility despite no previous genetic selection efforts, and the genetic correlations between JD susceptibility and important traits like milk yield were notably low.*
Periparturient hypocalcemia is a complex metabolic disorder that occurs at the onset of lactation because of a sudden irreversible loss of Ca incorporated into colostrum and milk. Some cows are unable to quickly adapt to this demand and succumb to clinical hypocalcemia, commonly known as milk fever, whereas a larger proportion of cows develop subclinical hypocalcemia. The main goal of this study was to identify causative mutations and candidate genes affecting postpartum blood calcium concentration in Holstein cows.

The goal of this study was to identify individual genes, pathways, and molecular processes implicated in visceral fat deposition in dairy cows. Data from 172 genotyped Holstein cows classified at slaughterhouse as having low ( = 77; omental fold 5 mm in thickness and minimum fat deposition in omentum) or high ( = 95; omental fold 20 mm in thickness and marked fat deposition in omentum) omental fat were analyzed.
