User Guide – Calving Indicators Monitor

Path: Reports → Animals → Calvings → Indicators Monitor

This dashboard concentrates the most relevant reproductive indicators, linking calving events with birth rates, abortions, calf survival, and production projections. Proper use allows evaluating herd reproductive efficiency, anticipating feeding needs, and planning milk production.

1) Key Indicators (top section)

Indicator	Definition	Formula / Target	Usefulness
Calvings in the current period	Number of calvings that occurred within the selected date range.	-	Starting point for evaluating birth rate, survival, and future production.
Abortion Rate (%)	Proportion of abortions relative to total registered pregnancies.	Formula: Abortion Rate = # Abortions / # Pregnancies × 100 Target: <3% acceptable 3–5% warning >5% critical	Detects health, nutrition, or reproductive management issues.
Average age at first calving (years)	Average time between a cow's birth and her first calving.	Formula: ∑(Age at first calving) / # Heifers Target: 22–24 months. >30 months = low efficiency.	Measures reproductive precocity and its impact on profitability.

2) Main Charts

Chart	What it shows	Target / Formula	Application / Usefulness
Type of Calvings (pie)	Distribution of calvings by condition (normal eutocic, dystocia, cesarean, abortions).	>90% should be eutocic. Dystocia >5% → genetic/management alert.	Detect obstetric problems and adjust assistance protocols.
Calvings per month (line)	Monthly evolution of calvings in the period.	-	Identifies calving concentration and helps plan milk production curve.
Neonatal Mortality Rate (quarterly)	Proportion of calves dying before weaning.	Formula: # Calves dead before weaning / Total live births × 100 Target: <5% excellent; 5–10% warning; >10% critical.	Evaluates colostrum quality, calf management, and herd health.
Birth Rate (%)	% of reproductive-age cows that calved in the period.	Formula: # Calvings / Reproductive-age cows × 100 Target: 85–90% annually.	Global indicator of reproductive efficiency.
Births by gender (bar)	Ratio of female/male calves born.	Expected target: ≈ 50/50	Planning replacements and male calf management.

3) Projections

Projection	Includes / Formula	Target / Application
Reproductive Projection (table + chart)	Number of lactating animals, projected calvings, drying off, total herd projected, and estimated milk production.	Allows anticipating animal load and feeding needs in upcoming months.
Calving Interval (line)	Formula: ∑(Days between calvings) / # Cows	Target: 380–400 days. Long intervals reduce lactations per lifetime → review reproductive efficiency.

4) Weaning Survival

Indicator	Definition	Formula / Target	Application
Female / Male Survival (% weaned)	Percentage of live-born calves that reach weaning.	Formula: Live weaned calves / Live born calves × 100 Target: >95%	Evaluates quality of neonatal management, feeding, and health control.

5) Evolution of Abortion Rate (timeline)

What it shows: how abortion rate varies over months.
Application: Detect seasonality or issues associated with feeding changes, climate, or diseases.

📘 Quick Glossary

Eutocic: normal calving without complications.
Dystocia: difficult calving requiring assistance.
Birth Rate: proportion of cows calving out of eligible ones.
Neonatal Mortality: deaths of calves between birth and weaning.
Calving Interval: days between two consecutive calvings of the same cow.
Weaning Survival: % of live-born calves at weaning.

🚀 How to Apply This Dashboard in Practice

Monitor abortions and neonatal mortality as alert indicators.
Evaluate birth rate and calving interval to measure reproductive efficiency.
Review calving types and births by gender to adjust genetics and replacement management.
Use projections to plan feeding, drying-off, and milk production curve.
Track monthly evolution of abortions to implement timely preventive measures.
