Overview

Observational analysis shows physiological effects of regrouping in Holstein and Simmental cows, indicating varying stress sensitivity.

Key Points

  • Repeated regrouping caused a significant rise in adrenaline levels in Holstein and Simmental cows, indicating stress.
  • Holstein cows showed a 48.87% increase in adrenaline and a 15.37% rise in hemoglobin, revealing sensitivity to social stress.
  • Physiological parameters remained normal with no significant change in milk productivity or quality across breeds.
  • Red Steppe cows displayed relative resilience to social stress, with only an 18.23% elevation in cortisol levels.
