Reports > Animals > General Evaluations

This report is the most comprehensive in IdeasFarm, as it gathers all evaluation dimensions in a single dashboard. It is updated every 21 days, ensuring continuous and dynamic herd analysis.

The report combines:

• Absolute values per animal.
• Herd average.
• Individual differences.

1. Check Each Animal’s Z-score in IdeasFarm

Definition: Statistical measure indicating how many standard deviations a cow’s value is from the herd average.

Interpretation:

• Z > 0 → animal above average (positive performance).
• Z = 0 → animal at average.
• Z < 0 → animal below average (alert).

Usefulness: Quickly identifies outstanding and lagging animals for each indicator.

2. Value Difference

Definition: Difference between the cow’s individual value and the herd average.

Usefulness:

• Shows how much each cow contributes or subtracts in milk liters, fertility, health, etc.
• Quantifies the economic and technical impact of the animals.

3. Evaluation Areas Included

The report groups indicators into blocks:

• Production: milk liters, 305-day adjusted production, persistence, lactation peak, pasture conversion.
• Fertility and Reproductive Health: services per conception, open days, abortions, retained placenta, ovarian cysts.
• Health: metritis, endometritis, mastitis, somatic cell count.
• Body Condition (BCS): energy status scores.
• Management: protocol compliance, records.
• General Health (HT): diagnosed diseases, treatments applied.
• Linear Conformation (L): morphological traits associated with longevity and productive functionality.

4. Interpreting Tables and Charts

• Tables: show values per animal, herd average, difference, and Z-score.
• Charts: distribute Z-scores, helping visualize herd concentration ranges.

👉 Example: a group of cows with Z > +1 in production → productive elite; cows with Z < -1 → low performance.

5. Herd Average

Definition: Baseline representing average performance in each indicator.

Usefulness: Allows the producer to compare each cow against the real standard of their own herd (not external data).

📘 Quick Glossary

• Evaluation every 21 days: frequency of calculation for continuous monitoring.
• Value difference: positive or negative contribution of each cow relative to the herd.
• 305-day adjusted production (P305): comparison of normalized lactations.
• Lactation persistence: ability to maintain production after peak.

🚀 How to Use This Report in Practice

1. Analyze global Z-scores → identify elite cows (> +1) and at-risk cows (< -1).
2. Review value differences → detect which animals contribute most in liters, fertility, or profitability.
3. Evaluate indicator blocks:
• Production → select cows for genetics.
• Reproduction → correct fertility problems.
• Health → prioritize treatments or culling.
• Linear → select cows with better conformation for longevity.
4. Make management decisions:
• Retain high-value animals.
• Improve feeding/reproduction in lagging cows.
• Plan culling for cows with multiple negative indicators.
