If you’re planning to agist sheep on your vineyard over winter, consider entering into an agistment agreement.

Including biosecurity risks in this agreement can help avoid a plant pest, disease or weed being inadvertently moved onto your vineyard.

As an agistor of sheep, you also become part of the chain of responsibility for animal welfare when you have the sheep on your vineyard and when you are consigning them for transport off your vineyard.

To protect both yourself as the vineyard owner (agistor), and the potential agistee, the written agistment agreement should outline expectations and responsibilities, including:

  • Duration of the agreement;
  • Agistment fees and ability to re-negotiate;
  • Person responsible for caring for livestock and animal welfare;
  • Type, quantity and quality of feed; and
  • Access to the property by the livestock owner or person responsible for livestock welfare.

Other important considerations:

  1. The agistment history of the sheep: if the sheep have previously been agisted in vineyards in a Phylloxera Infested Zone (PIZ) or Phylloxera Risk Zone (PRZ), do not accept them for agistment in a vineyard in a Phylloxera Exclusion Zone (PEZ). It is also not advised that sheep are moved for agistment either between vineyards located within a PIZ, or PRZ, or moved between vineyards within these Phylloxera Management Zones.
  2. Weed transfer: to minimise the risk of weed transfer onto your vineyard, ask if the sheep have been on a previous property with problematic weeds. Request that sheep be shorn prior to entering your vineyard to reduce the potential for fleeces to hitchhike weed seeds. Ensure you also advise the potential agistee of any harmful weeds on your property that could be tracked off when the agistment ends.
  3. Agrochemical residues: ensure you advise the potential agistee of any re-entry periods for grazing that apply (these might be from chemicals already applied before the agistment period, or chemical applications planned during the sheep occupancy).
  4. Sheep diseases: gain some knowledge of sheep diseases to ensure that you can look out for anything unusual and contact the agistee if you are concerned with the health of the sheep.
  5. Requirements for your state under the National Livestock Identification System (NLIS): The NLIS is Australia’s system for the identification and traceability of cattle, sheep and goats. It combines three elements to enable the lifetime traceability of animals: (1) all livestock are identified by a visual or electronic eartag/device; (2) all physical locations are identified by means of a Property Identification Code; and (3) all livestock location data and movements are recorded in a central database (from specified movement documents). The NLIS database must be notified when 1 or more sheep are moved to a property with a different Property identification Code (PIC) for any purpose including agistment. Notification is through completion of documentation by the owner of the animals at the destination property.
  1. A National Vendor Declaration or Movement Waybill. These are mandatory documents that must be completed when you purchase and sell sheep in South Australia but check with other states for requirements; and
  2. A ‘National Sheep Health Declaration’ from the potential agistee. This Declaration is mandatory for all sheep movements in South Australia and for sheep being moved into New South Wales and Tasmania.

Upon signing of the agistment agreement

Assuming you have determined that the sheep to be agisted do not pose a potential phylloxera risk to your vineyard and that your vineyard is in a PEZ:

  • Ensure you have sighted the NLIS documentation (discussed above) if applicable.
  • Discuss farm-gate hygiene requirements of the sheep truck with the agistee: query if the truck has been near vine rows in a PIZ or PRZ within the last month. If yes, communicate with the agistee that this poses a heightened phylloxera risk to your vineyard unless the truck has been heat treated at 45˚C for 1.5 hours or at 40˚C for 3 hours, prior to leaving the PRZ or PIZ. If this disinfestation has not occurred, request that an alternative truck is required to transport these sheep to your vineyard. Also communicate to the agistee that the sheep truck must be clean of all soil and plant material upon arrival at your vineyard.

Upon arrival of the sheep truck at your vineyard:

  • Verify that the truck is clean of soil and plant material upon entry to your vineyard.
  • As you would for other visitors to your site, require the truck driver to sign in via your visitor record book and answer questions as to where the truck has been (in terms of phylloxera management zones) in the last month and where the driver has been within the same timeframe.
  • Avoid loading/unloading the sheep directly down vine rows.
  • Limit unnecessary movement of the driver down your vine rows.
  • Retain agistment records for the entry and exit of sheep to your vineyard.

Upon exit of the sheep truck from your vineyard:

  • Ensure the truck is clean of all soil and plant material.

Remember that when you are in charge of an animal, you are responsible for maintaining its welfare. This also extends to transport of your agisted stock where applicable. Meat & Livestock Australia has a free pictorial guide “Is the animal fit to load?” to help assess if your agisted livestock are fit for the intended journey and your responsibilities.
