Reports > Animals > Weights > Indicators Monitor

This dashboard organizes and compares animal weights by groups (females, males, milking cows, dry cows, and transition cows). Its goal is to provide a clear view of body condition, weight gain, and productive efficiency, helping plan nutrition, health, and reproduction.

1. Average Weight of Adult Cows

Definition	Average weight of all recorded adult cows.
Formula	Average weight = (Σ weights of adult cows) ÷ (number of adult cows)
Target	500–600 kg (depending on breed).
Usefulness	Evaluates whether the herd is within the expected range. 👉 Low weights → nutritional deficiencies. 👉 High weights → risk of metabolic problems (e.g., ketosis).

2. Average Weight of Adult Bulls

Definition	Average weight of recorded bulls.
Target	600–900 kg (European breeds) / 500–700 kg (Zebu breeds).
Usefulness	Monitors body condition of breeding bulls, crucial for fertility.

3. Average Birth Weight

Definition	Average weight of calves at birth.
Target	Dairy breeds: 30–40 kg. Beef breeds: 35–45 kg.
Usefulness	Evaluates neonatal health and gestation quality. 👉 Low weights → maternal nutrition issues or prematurity. 👉 High weights → risk of dystocia.

4. Females – Category Chart

Includes: heifers, milking cows, dry cows, and transition cows.

Definition	Shows the weight of each group compared to its expected range.
Target	Heifers: progressive growth curve, reaching 55–60% of adult weight at first service. Milking cows: maintain stable weight, avoiding excessive postpartum loss. Dry cows: 500–600 kg, adequate body condition for next calving. Transition cows: 450–500 kg, should enter calving in good body condition.
Usefulness	Detects deviations between groups and supports targeted feeding decisions.

5. Males – Category Chart

Includes breeding bulls and steers.

Definition	Shows weight and projected gain of growing males and breeding bulls.
Target	Beef steers: daily gain 0.8–1.2 kg/day. Breeding bulls: maintain condition without overweight.
Usefulness	Planning fattening and bull selection.

6. Milking Herd

Definition	Average weight of milking cows and their daily gain.
Target	Maintain stable weight with ±10% fluctuations during lactation.
Usefulness	Sharp postpartum drops indicate negative energy balance, affecting fertility.

7. Dry Cows

Definition	Average weight of cows in the dry period.
Target	500–600 kg, body condition 3.0–3.5 (scale 1–5).
Usefulness	Preparation for a smooth calving and better start in next lactation.

8. Transition Cows

Definition	Weight and gain of cows in transition (3 weeks before and after calving).
Target	Stable weight, no excessive loss.
Usefulness	Critical phase → detect weight loss associated with metabolic disorders (ketosis, hypocalcemia).

9. Breeding Bulls

Definition	Average weight and gain of breeding bulls.
Target	Maintain body condition 3.0–3.5 (scale 1–5).
Usefulness	Prevent overweight or underweight that reduce fertility and libido.

10. Steers

Definition	Average weight and gain of steers for fattening.
Target	Depending on system: • Intensive fattening: 350–450 kg at slaughter. • Extensive fattening: > 450 kg.
Usefulness	Plan optimal time for sale or slaughter.

📘 Quick Glossary

Average weight: mean value of animals in a group.
Average daily gain (ADG): average daily weight increase.
Heifers: young females before first calving.
Milking cows: females producing milk.
Dry cows: cows in resting period between lactations.
Transition cows: cows near or just after calving.
Steers: castrated males for fattening.
Breeding bulls: bulls used for reproduction.

🚀 How to Use This Dashboard in Practice

Monitor average weight by group and compare with targets.
Track daily gain to detect if diet is well balanced.
Observe heifer growth curves to ensure they reach ideal weight for first service.
Check stability in milking and transition cows, avoiding sharp losses.
Use steer and bull data to plan fattening and fertility management.
