What cattle need in September

From the care calendar — the things that come round once a season for cattle in South Australia.

1. Bloat risk on the spring flush

   Lush clover and legume-heavy pasture in spring is when bloat happens. Fill them up on hay before letting them onto it, introduce new pasture gradually, and don't turn hungry cattle out onto it first thing.

2. Snake season — tidy the hiding places

   They come out with the warm weather. Clear long grass and rubbish piles near the house, sheds and feed areas, and know where your nearest after-hours vet is.

Plants in South Australia that hurt cattle

Worth walking the fence lines for. Each one links to the official page with photographs, because a description alone is not enough to identify a plant.

• Garden plant or tree

  Oleander

  Look for

  Tall garden shrub with long, leathery, dark green leaves and white, pink or red flowers. Very common in old farm gardens and along driveways.

  Worst

  All year. Dried clippings are just as deadly and more likely to be eaten.

  What it does

  Attacks the heart. A few leaves can kill a horse or a cow. Deaths most often happen when someone prunes it and the clippings end up where animals can reach them.

  What to do

  Know where it is on your place and make sure nothing can reach over a fence to it. NEVER put clippings anywhere near a paddock, a feed area or a compost heap animals can get at.

• Weed

  Bracken fern

  Look for

  Coarse triangular fronds on a tough stem, often in big patches on poorer or timbered country and along bush edges.

  Worst

  Late summer and autumn, and whenever feed is short.

  What it does

  Horses get a thiamine deficiency — wobbling, then staggering. Cattle bleed internally and can develop bladder cancer with long exposure. Both build up over weeks of eating it.

  What to do

  Keep animals out of heavy bracken country when there's nothing else to eat, which is when they start on it. Look for it along the timbered edges rather than in the open.

• Weed

  Pimeleaalso Flaxweed, St George disease

  Look for

  Small slender native herb with narrow leaves and small clustered cream or pink flower heads.

  Worst

  After good rain following dry, especially on inland and western country.

  What it does

  Causes swelling under the jaw and brisket and severe illness in cattle. Even the dust off dried plants in hay can do it.

  What to do

  Watch for it after rain breaks a dry spell, and be careful with hay cut from country where it grows.

• In the water

  Blue-green algaealso Cyanobacteria, Pond scum

  Look for

  Not a plant — a bright green or blue-green paint-like scum on still water, often blown up against the downwind edge of a dam.

  Worst

  Hot, still weather in summer, especially in a dam that's dropping.

  What it does

  Can kill within hours of drinking. Animals are often found dead at the water's edge.

  What to do

  Fence animals off any dam with scum on it and cart water until it clears. Check dams on hot still days — that is when it blooms, and it can appear in a day.

Ring a vet now if you see any of these

Not a list to think about — a list to act on. Every one of these is measured in hours.

• Suspected snake bite is an emergency — antivenom is time-critical.
• An animal that can't get up or won't bear weight needs a vet now.
• Laboured breathing is an emergency.
• Bloat is rapidly fatal in ruminants and needs a vet now.
• A suspected poisoning needs a vet now — what they ate changes the treatment.
• Birthing trouble is measured in minutes, not hours.
• A prolapse needs a vet now.
• Seizures need a vet now.
• Uncontrolled bleeding is an emergency.
• Pale or blue gums mean shock or severe anaemia — a vet now.
• Metabolic collapse is treatable but only quickly.
• Choke needs a vet now.
• Sudden eye injury or blindness needs a vet now — eyes don't wait.
