A big dairy cow needs a different checklist
A Holstein is not simply a larger cow to load. She is tall at the shoulder and hip, wide through prominent pin bones, and — if she is milking — carrying an udder that fills steadily through the day. Each of those facts changes the transport plan. The trailer needs genuine headroom so she can stand and brace at her natural height, a race and doorway wide enough that her hips clear without banging, and a departure timed shortly after milking so she is not riding for hours at her fullest and most uncomfortable. A dry cow or a heifer travels more simply, but the size and the footing rules stay the same.
Before loading: udder, feet, and fitness
Milk a lactating Holstein as near to loading as the schedule allows, and think about the far end too: a long journey that ends with no milking arranged until morning is poor planning for a high-yielding cow. Walk her across the yard and watch her stride — a cow that is even slightly lame will be markedly worse after standing and bracing on a moving floor, and transport can turn a treatable foot problem into a serious one. Check that she is eating, ruminating, and breathing normally, and that her udder shows no heat, hardness, or swelling; a cow developing a problem in the udder should be seen by a veterinarian before she is asked to travel, not discovered at the destination. Offer hay and water right up to loading rather than sending her off hungry.
Loading and space in the trailer
Bring her up a solid, cleated ramp through a race she already knows if possible, working quietly at the edge of her flight zone and letting her pick her moment to step up. Inside, partition her so she can spread her feet and lean against something solid in corners, without space to turn or fall heavily. Bed generously — tall cows that go down on a hard, slick floor struggle to rise and can injure hips and hocks badly. Keep her with a familiar companion where you can, and never pen her tightly against horned cattle.
On the road: smoothness is welfare
Drive a Holstein like the tall, top-balanced animal she is. Gentle pull-aways, long braking distances, and slow, wide corners matter more for her than for shorter, stockier stock. Stop on long journeys to confirm she is still standing comfortably, check the bedding has not bunched away from under her, and offer water. Watch her udder at stops on longer hauls and note any restlessness, kicking at her belly, or milk leaking steadily, which tell you the interval since milking is becoming a welfare issue, not just a schedule detail. Ventilate well in warm weather — a trailer of large dairy cows generates considerable heat and moisture — while shielding her from cold rain driven at standing height in winter.
Arrival, milking, and records
Unload into a pen with water and hay, and for a milking cow make the parlour part of the arrival plan: she should be milked at the destination without an extended wait, and her udder checked as she is. Over the next day watch appetite, rumination, milk yield against her norm, and how freely she moves; a sharp drop in yield, a hot quarter, feverish behaviour, or worsening lameness after travel warrants a veterinarian promptly. Dairy cows carry long, consequential histories — calvings, treatments, yields, breeding — and gaps in that history cause real mistakes at the receiving end. Sending those records assembled in a KinsLe Pet Passport, one portable packet the new herd manager or vet can open on arrival, protects the cow from decisions made in the dark.
