Livestock Transport Calculator

Yes — with animal type, average weight, and journey duration held fixed, a longer or wider trailer produces a larger floor area, and maximum head capacity is that area divided by the required space per head, so a bigger trailer footprint always allows the same or more animals to be loaded within the space guidelines this calculator uses.

The allometric formula scales required space with body weight raised to the power 0.67 rather than to the power 1, reflecting research findings that larger animals need proportionally less floor space per unit of body weight than smaller animals do — space requirements grow more slowly than weight itself.

This calculator takes the larger of the allometric formula's result and the species-specific regulatory minimum, so at typical body weights for cattle, sheep, or pigs the regulatory floor often exceeds what the general formula alone would suggest, ensuring the animal always gets at least the minimum welfare-based space allowance.

The maximum continuous journey time before a mandatory rest stop varies by species in this calculator's figures, reflecting general differences in physiological tolerance to prolonged transport across species — sheep and goats are commonly given longer continuous transport allowances than cattle, pigs, or horses before requiring a rest, water, and unloading stop.

No — these are general planning estimates drawn from widely referenced livestock transport guidelines, not a substitute for the specific regulations that apply in your jurisdiction and species, which can differ meaningfully by country, region, and animal category. Always confirm requirements with your local regulatory authority before a real shipment.
