Overview

Randomized trial shows automated live weight monitoring in dairy ewes, indicating nutritional status shifts and implications for management.

Key Points

  • This research aims to evaluate the effectiveness of a walk-over-weighing system in detecting live weight changes due to nutrition in dairy ewes.
  • Two experiments conducted: an indoor nutritional challenge with 24 non-lactating ewes, and a grazing trial with 48 lactating ewes.
  • Evaluation of live weight sensitivity using walk-over-weighing systems under various feeding conditions.
  • Data compared for live weight differences between nutritional treatments with statistical analysis (p < 0.001).
  • Consistent live weight differences detected due to nutritional treatments, approximately 5% variation observed.
  • System reliably tracked live weight dynamics before changes in body condition score were measurable.
  • Short-term weight changes detected may also be influenced by factors such as gut fill and hydration dynamics.
