Grazed pasture is generally the most cost-effective nutrient source in pasture-based dairy systems. A recent study compared traditional electric fence to GPS technology connected to cow collars. The objective was to measure the technology efficacy and pasture use outcomes.

INSIGHTS: As land availability and use is subjected to more rigor, technology to optimize pasture use is an important advancement. Be honest. Have you ever discussed an individual cow’s daily pasture allocation? It should be a great place to begin a new conversation.
