Our New PhD Graduate: Marina Loch Successfully Defended Her Doctoral Thesis!

Today, our institute hosted the defense of Marina Loch's doctoral thesis, which focused on the crucial topic of "The Impact of the Neonatal Period on Dairy Cow Health and Productivity."

Summary of the Thesis:
The first three weeks of life, known as the neonatal period, are critical for calf development. During this time, newborn calves adjust to their new environment and encounter microorganisms for the first time. Marina’s research examined how the development of the calf’s gut microbiota and immune system influences their future health and productivity.

The study revealed that acute-phase proteins produced during inflammatory responses could be linked to future weight gain and lactation indicators. The presence of certain bacteria, such as Peptostreptococcus, was associated with increased inflammation and negatively impacted future performance. Conversely, bacteria like Collinsella were connected to lower inflammation and better productivity outcomes.

These findings enhance our understanding of the relationship between gut microbiota and the host, offering new ways to improve dairy cow performance by managing gut microbiota during the neonatal period.

Congratulations to Marina on this outstanding achievement!
