Article Summary: A practical, farm-specific biosecurity plan starts with mapping your biggest disease pathways, then sets clear rules for animal introductions, visitor hygiene, equipment cleaning, and wildlife control. Put the protocols in plain language, train every staff member, and review records each season; the result is a living document that shields your herd and keeps daily routines on track.
A tidy paddock and a healthy herd start long before you open the gate each morning. A written biosecurity plan gives you a simple, shareable roadmap for keeping pests and diseases off your property and for acting quickly if something slips through the net. The following guide walks you through building a plan that fits your farm, not a theoretical ideal. We cover how to pinpoint weak spots, set practical rules, involve your team, and keep the document useful year after year.
Know Your Risks: A Farm‑Specific Assessment
Biosecurity works best when it reflects the real‑world traffic on and off your paddocks. Start by taking stock of every pathway a pathogen could travel. Walk the boundary fences, note drainage lines and shared laneways, and think about everything that moves: livestock, people, vehicles, water, feed even wind‑blown seeds.
Ask yourself:
-
Which animals arrive most often? Auction stock, agisted cattle, calves coming back from rearing blocks—all bring different disease profiles.
-
Who else touches your ground? Contractors, shearers, service technicians, and even curious neighbours can ferry microbes on boots or tyres.
-
Where do wildlife and vermin gain entry? Gaps in fencing, roosting sites in sheds, and open feed stores are magnets for pests.
Jot each risk in a simple matrix (likelihood down one axis, potential impact across the other). That visual snapshot helps you decide where to focus first. A high‑impact, high‑likelihood threat say, cattle tick in a warm coastal district deserves immediate attention, whereas a low‑impact, low‑likelihood issue might wait until resources free up.
Set the Ground Rules: Core Biosecurity Protocols
Hard‑and‑fast rules remove doubt when the ute rolls in or a new bull arrives. Use the headings below to build a living checklist rather than an intimidating manual.
Animal Introductions
Quarantine new stock for a set period often 7–14 days for cattle and small ruminants far enough from resident mobs to prevent nose‑to‑nose contact. Record temperature checks and vaccination status during the stand‑off period. Once animals clear the list, integrate them gradually, starting with lower‑risk groups such as dry cows before mixing with freshly‑calved animals.
Movement and Travel
Clean and disinfect trailers, crates, and ramps before they leave for the saleyards and again before they reverse back toward your loading race. Where possible, avoid returning unsold animals; if you must, treat them as new introductions. If you or staff visit other farms, keep a spare pair of boots and overalls in the ute and change before re‑entering your own yards.
People and Visitors
A visitor book at the front gate does more than satisfy the paperwork it encourages a quick chat about on‑farm hygiene. Offer disposable overshoes or a footbath, and steer non‑essential visitors away from maternity pens and hospital paddocks. Children’s play areas, if you host farm tours, should be well clear of livestock zones.
Vehicles and Equipment
Dedicate specific machinery slurry spreaders, feed carts, mineral lick troughs to your own enterprise wherever practical. When sharing or hiring equipment is unavoidable, hose off loose debris, scrub contact surfaces with a farm‑approved disinfectant, and allow full drying time before use. Mark “clean” and “dirty” parking areas so drivers know exactly where to stop.
Feed and Water
Buy feed from suppliers who can provide a quality assurance statement or certificate of analysis. Store concentrates in sealed silos or covered bins, and keep forage stacks fenced against stock and wildlife. Clean troughs routinely and fence off dams or creeks used by both livestock and feral species to reduce cross‑contamination.
Farm Pests and Wildlife
A combined approach physical barriers, habitat reduction, and monitoring—beats a single control method. Maintain tight fences, mow grassed headlands to discourage rodents, and empty stagnant water where mosquitoes breed. Document how often baits or traps are checked and who is responsible.
Manure and Dead Stock
Compost or spread manure on well‑drained ground away from feed‑out areas. Remove dead stock promptly; burial sites should be deep enough to deter scavengers and well clear of watercourses. Where rendering is the norm, store carcasses on a concrete pad and arrange pick‑up within 24 hours.
Put It in Writing: Clear Documentation and Practical Signage
A plan only works when everyone can find and understand it. Write in plain language, avoiding jargon. Map your farm with coloured zones: red (high‑risk), amber (controlled), and green (clean). Keep the master document in the office and post laminated quick‑reference sheets in key spots such as the dairy pit, machinery shed, and staff room.
At entry points, a gate sign can list essentials: “Stop. Sign in. Disinfect footwear. Call 0400 XXX XXX before entering.” Inside the calf shed, a small poster might outline the daily order of work youngest to oldest to minimise disease transfer. Checklists taped to the quarantine pen rails remind staff what to record before an animal leaves isolation.
Bring Everyone on Board: Training and Team Buy‑In
Rules stick when people believe they matter. During induction, walk new employees through each biosecurity zone and explain the “why” behind footbaths and sign‑ins. Seasonal staff deserve the same tour—even if they are only on the books for a few weeks. Short toolbox talks, perhaps before Monday milking, keep procedures fresh without dragging out the day.
Assign clear ownership of tasks: one person refills disinfectant, another updates the visitor log, a third inspects fences for wildlife breaches. Rotate roles quarterly so knowledge doesn’t sit with a single individual. Celebrate wins—such as a full year without a scouring outbreak—to reinforce the value of diligence.
Keep It Alive: Monitoring, Records, and Regular Updates
Treat your plan as a working document rather than a one‑off compliance exercise. Record every biosecurity incident, from a sick calf to a truck that arrived without using the wash‑down bay. Review logs monthly; any recurring issues signal a need to tighten procedures or invest in infrastructure.
Set a calendar reminder for an annual audit. Walk the farm with fresh eyes, invite your vet or an external adviser, and compare current practice with the written plan. Update contact lists, supplier assurances, and disease watch‑lists to reflect new threats whether that’s a regional Mycoplasma bovis alert or a surge in foot‑and‑mouth overseas. By closing the loop between observation and revision, you keep the document and your defences fit for purpose.
Final Word
Building a robust biosecurity plan is less about thick binders and more about consistent, everyday habits. By understanding your unique risks, writing clear protocols, involving the whole team, and revisiting the plan regularly, you give your herd the best chance to thrive—season after season, year after year.
Until we meet again, Happy Biosecurity!
