Livestock Weight Estimator
| Parameter | Value | Formula Component |
|---|---|---|
| Girth Squared ($\text{G}^2$) | 32,400 | Major determinant of volume/weight. |
| $\text{G}^2 \times \text{Length}$ | 4,860,000 | Volume Proxy (Cubic Centimeters). |
| Weight Conversion Factor ($\text{F}$) | 800 | Density/Conversion factor ($\text{kg} / \text{cm}^3$). |
| **Formula Used** | $\text{Weight} = (\text{G}^2 \times \text{L}) / \text{F}$ | |
Note: The formula $\text{Weight} = (\text{G}^2 \times \text{L}) / \text{F}$ is a common approximation. It assumes a cylindrical shape and uses a factor (F) adjusted for the animal's density and breed.
Measurement and Animal Type
Measured behind the shoulder blade.
Measured from the point of the shoulder to the pin bone.
Conversion Factors (F)
The factor $\text{F}$ is the divisor in the formula, representing the density-based constant ($\text{Weight} = (\text{G}^2 \times \text{L}) / \text{F}$).
- Cattle (Mature Beef): $\text{F} \approx 800$
- Cattle (Dairy/Holstein): $\text{F} \approx 850$
- Pig (Mature): $\text{F} \approx 690$
- Sheep (Mature): $\text{F} \approx 300$ (Note: Often uses a different formula, F is adjusted for consistency here.)
