Where You Stand vs. National Trend

Your score plotted against the national Pipeline Index over the past two years.

The Pipeline Index is a composite score (0–100) built from four sub-scores, each measuring a different dimension of replacement pipeline health:

ComponentWeightWhat It Measures
Heifer Supply40%Your heifer-to-cow ratio vs. ideal replacement rate
Price Signal25%Market stress — how replacement costs compare to benchmarks
Culling Pressure20%Whether your cull rate is sustainable given your pipeline
Semen Mix Momentum15%Sexed semen investment, offset by beef-on-dairy diversion

Zones: Green (70–100) means your pipeline can sustain your herd comfortably. Yellow (40–69) means pressure is building — you're managing, but margins are thin. Red (0–39) means you're replacing faster than you're growing, and market exposure is high.
