Implication

Research assesses biochemical and immune-hematological changes in dry cows, suggesting new therapeutic approaches.

Key Points

  • This research aims to evaluate changes in biochemical and immune-hematological parameters in dry cows during late gestation.
  • Analyzed 10 immuno-hematological and 17 biochemical parameters in 38 Holstein cows.
  • Conducted assessments 60 and 20 days prior to calving dates.
  • Performed statistical analyses using PAST and R software, including Wilcoxon W and Spearman's rank correlation.
  • Serum hematocrit level and absolute lymphocyte counts, including T-lymphocytes, significantly increased (up to 31.3%).
  • Absolute segmented neutrophil count and phagocytic activities decreased (up to 20.2%).
  • Serum levels of total protein, urea, and cholesterol decreased significantly (up to 43.8%).
  • Triglyceride levels increased by 22.8%, along with changes in glutamate dehydrogenase and lactate dehydrogenase activities.
