Matthew Lieschke and Dr Bill Johnson from South East Local Land Services led the discussion and practical session about managing lambs and ewes at lamb marking. Lamb marking is a key animal husbandry task for people raising lambs and typically involves ear tagging, vaccination, castration and tail docking.
Plan to mark lambs at 2-8 weeks of age. Younger lambs are likely to recover faster. Lamb marking should be completed before the lambs are 12 weeks old. If you have lambs arriving over a long period, it might be better to have several lamb marking times. Marking before the end of October reduces the risk of fly strike.
Preparation of the site and equipment will help you to minimise infections. Generally a temporary holding pen out in a paddock is cleaner than the sheep yards and a good place to do marking. Avoid mud and dusty conditions. Cover surfaces where equipment is placed with a clean cloth or towel. You can use a lamb cradle or hold the lamb securely in your arms (see photo).
Disinfect any equipment between animals using Hibitane (Chlorhexidine). Push needles into a sponge soaked in the disinfectant solution after each injection. Note that most other types of disinfectants are deactivated by organic matter and need to be changed frequently.
Vaccinate each lamb at lamb marking with 5 in 1 or 6 in 1 vaccine for sheep with a follow up booster vaccination 4 weeks later. This is injected subcutaneously (under the skin) either in the neck or the brisket (if holding the lamb). Needles for sheep vaccinations should be sharp, 18 gauge and 6mm or 12mm long.
Lambs that will be kept for more than 2 years can be vaccinated with Gudair vaccine for lifelong protection against Johne’s Disease. Be careful with Gudair vaccine which can have bad side effects for people who accidentally touch or inject it.
[Options now available for reducing pain at marking include Numnuts and Buccalgesic - Ed.]
The recommended tail length for tail docking is three palpable joints. In ewe lambs, a tail of this length covers the vulva. Shorter tail lengths take longer to heal, can affect the movement of the tail and increase the likelihood of fly strike. If you are using lamb marking rings, the ring should be placed on the joint rather than the bone between joints, the tail will usually drop off in about 3-4 weeks.
Castration of male lambs is often done by placing a lamb marking ring over the scrotum, making sure that both testicles are included and that the teats are not included before releasing the ring into place (see ‘A producers guide to sheep husbandry practices’ below for more details).
Lambs need to have an ear tag with the Property Identification Code (PIC) if they will ever be moved off the property. The tag can also have other information such as a number for the flock or individual sheep and a V if vaccinated for Johne’s Disease. Different coloured ear tags are used for each year but this is not compulsory. Pink tags are only used to replace tags where a sheep was born on another property and has lost its tag. Use a tag applicator that matches the type of tags. Dip the tag in disinfectant before applying half way along and half way up the ear. A convention is that ewe lambs are tagged in their right ear, ram/wether lambs are tagged in their left ear.
After marking, allow lambs time to ‘mother up’ with the ewes. It can help to put the lambs in the middle of the paddock and then let the ewes out to the lambs and give them time to find each other. The male lambs will often lie down.
Plan to wean at 12-14 weeks of age. In tougher years, it can be better to wean earlier so that ewes can start to put weight on in preparation for joining. By 8 weeks old the lamb is getting less than 10% of its nutritional intake from milk. Wean lambs onto your best paddocks that have been rested for 3 months to reduce worm burdens and don’t have nasty grass seed heads. Lambs are usually given their first drench at weaning. Weaning is also a good time for the lambs’ booster vaccination (if it hasn’t already happened).

This field day was about the practical aspects of fencing. Andy Taylor and Shane Laverty from the Rural Landscapes Program, South East Local Land Services discussed the theory of fencing and led a fencing demonstration.
There are some principles for fence design that usually apply. The best fence on the farm should be the boundary fence. When considering gate sizes choose larger gates that Rural Fire Service trucks can fit through – as a standard option choose 12′ (3.6m) wide gates if possible. If you have livestock, hang the gate on one side of the post so the gate can be opened flush with the fence when moving stock and the animals won’t get stuck between the gate and the fence. Gates located in corners usually work best – it is often difficult to get animals to go through a gate in the middle of a straight fence.
The type of fence that you install should be influenced by considerations such type of stock, cost, understanding where the water runs, different soil types, land capability, vegetation and watering points. A property planning field day can help with planning the type and location of fences. In some cases electric fences (permanent or temporary) may be an option.
Effective personal protection equipment is vital when fencing. This includes gloves, eye protection and protective ear muffs if you are using noisy mechanical equipment (for example when banging in steel posts).
There are many choices for fencing materials. Low tensile wire just keeps on stretching – medium tensile wire is a better option. Hinged joint fencing mesh comes in many sizes. The numbers in the hinged joint mesh name refer to the number of horizontal wires, fence height and distance between the vertical wires. For example, a 6/70/30 hinged joint mesh has 6 line wires, is 70cm high and the vertical wires are 30cm apart – this size suits smaller animals like sheep. A boundary fence might use 8/90/30. Hinged joint mesh has a top and bottom. The side with the smaller gaps is supposed to be closest to the ground. Usually you put plain wire through the steel posts (star pickets to the non-farmer) lined up with the top, middle and bottom of the hinged joint mesh and attach the mesh to the wires using fencing clips. Two more wires will usually be run in the space above the mesh. To get the fence height right, bang the steel posts into the ground until the bottom hole is just above the ground.
When repairing fences check the existing strainer posts, stays, steel posts and wire and see what can be salvaged. The most important part of the fence is the end assembly (strainer post and stay) and the most common type are steel. These can be galvanised or black steel and can be purchased as a complete kit.

NSW DPI Primefact 302 Fat Scoring Sheep and Lambs has information about how to do fat scoring.
Pasture planning: our pastures in the Southern Tablelands follow a somewhat predictable growth pattern with most pasture growth in September and October. To minimise the costs of supplementary feeding, it is helpful to match stocking rates to pasture growth. In dry years there will be less grass.
Graz Clock is a spreadsheet created by Doug that can be used to help with understanding pasture cycles and planning stocking.
Attending a PROGRAZE course will teach you about how to manage pastures and grazing.
Supplementary feeding: if there is not enough grass and you want to keep your sheep then you will need to feed them extra. The amount to feed depends on the type of sheep (dry, pregnant, lambs, weaners) and the amount of grass in the pasture.
Feed such as wheat, barley, oats, corn or sheep nuts needs to be introduced slowly (say 50g/head/day for three days, then 100g/head/day and so on) so that you don’t poison your sheep. If they have never had the feed before then you need to be especially careful that a few brave sheep don’t eat the lot and die. Lupins are a safe option.
NSW DPI Primefact 331 Supplementary feeding of sheep in southern NSW has more information.
[See also the NSW DPI Drought and Supplementary Feed Calculator app which allows you to calculate feeding options for your sheep and pastures.]
Lambing time: generally it works best to time lambing so that lambs are being weaned when there is lots of grass. In the NSW Southern Tablelands, lambing in August means that the young lambs can take advantage of the peak grass growing time (September/October) and minimises the amount of supplementary feeding needed.
Joining: sheep have a 150 day gestation period so you need to put the rams in with the ewes in early March to get lambs in August. This is known as joining and can go on for about 5 weeks. You need to feed your rams well before this (lupins are good). Ewes will have more twins and triplets if they are fat score 3 or higher at joining.
Lamb marking is generally done when the lambs are two to six weeks old. This can involve ear marking, ear tagging, castration, tail docking and vaccination.
Shearing: in the merino wool industry, shearing has traditionally been done at the end of June but this means that the sheep use extra energy to keep warm instead of growing bigger lambs. If you shear sheep in winter you will need to give them supplementary feed.
Shearing in late November/early December can help reduce flystrike and problems with seeds burrowing into the skin.
It is best not to shear in the month before lambing when pregnant ewes need to spend lots of time eating.
Many meat sheep such as Dorpers don’t shed fully and may need shearing.
Mostly you need to shear when the shearer is available.
Fly strike: sheep with wet fleece or dags can get flystrike in the warm months. This is where flies lay eggs on damaged skin and maggots hatch and feed on the skin. Usually this happens around the tail (breech strike) or along the back (body strike). Generally sheep with wool have more problems with flystrike. See the FlyBoss website for more information about treatment and prevention measures.
Crutching is shearing the wool from around the tail and inside back legs to keep dags off the breech area. This helps to reduce breech strike. It is often done before and during the fly season and prior to lambing.
Parasitic worms: there are three main types of intestinal worms affecting sheep in the Capital region: Barber’s Pole Worm, Brown Stomach Worm and Black Scour Worm. If left uncontrolled, these can kill your sheep. Best practice worm management combines pasture management, faecal worm egg counts (WEC) and effective drenching. You need to do regular WECs if you want to have any idea about what is happening with worms in your sheep.
Kate Sawford, District Veterinarian for the Braidwood Region has written a useful guide to Controlling Worms in Sheep in the Braidwood Region.
The WormBoss website has extensive information about managing worms in sheep and helps you decide when drenching is needed. The Capital region is in the WormBoss NSW non seasonal rainfall area.
Worm egg count test kits are available from South East Local Land Services offices and rural suppliers. The test kit is free and has information about the costs for the tests.
Moving sheep around yards
Sheep need to be moved into and around yards for routine tasks such as fat scoring, shearing, hoof trimming, drenching and vaccinations. A sheep dog can help with this but many people on small farm holdings use a bucket with some feed rattling in it instead.
A bugle shaped layout for yards works well for funnelling sheep into a race or small space.
It is easiest to move sheep if you are beside them. The balance point is at their shoulder. If you move forward from this towards the head then the sheep will go backwards, if you move behind the balance point towards the back leg then the sheep moves forwards. Mostly it doesn’t work to stand behind the sheep. This all takes practise.
Drench is an oral treatment for worms. The WormBoss website provides extensive information about selection and use of drenches.
You need to know the weight of your sheep before drenching (so you need scales).
Drenching guns are often rather inaccurate in the doses they deliver. Use a beaker to collect a number of doses (say 8-10) to check for accurate volume.
Quarantine drench any new sheep arriving on your property and keep them in a quarantine paddock for at least three days. See NSW DPI Primefact 477 Quarantine Drenching – Don’t Import Resistant Sheep Worms.
Drenching at weaning is encouraged by Doug (even when WECs are low).
This video about drenching technique may be helpful.
Sheep are generally vaccinated with 5 in 1 or 6 in 1 vaccine. The vaccine is injected subcutaneously (under the skin), usually behind the ear on the neck.
This video about injecting technique may be helpful.

At the Working with Weeds field day, Alison Elvin from Natural Capital Pty Ltd presented a compelling and informative story about weeds. Warren Schofield from ACT Biosecurity and Rural Services and Alice McGrath from South East Local Land Services also presented information on weed management and planning on the day.
According to the Australian Government it is estimated that weeds cost Australian farmers approximately $1.5 billion a year in weed control activities and $2.5 billion in lost agricultural production. So why are weeds such a problem and can we change our thinking to manage them better?

Former NSW Department of Agriculture Sheep and Wool Officer, Col Langford, led an informative and interactive discussion aimed at improving the skills and knowledge of livestock managers. An outdoor practical session followed where participants learned about estimating the age of a sheep, how to catch sheep and fat scoring along with pasture and weed assessment.
South East Local Land Services District Veterinarian, Dr Kate Sawford detailed the legislative requirements for Property Identification Codes (PICS) and the National Livestock Identification System (NLIS). Did you know that all properties with stock (even just one animal) need a PIC? If you move sheep from one property to another then you need to record this in the online NLIS.
There was also a discussion about drenching, sheep diseases and routine management of sheep. The WormBoss website is a good resource for finding out managing intestinal worms in sheep to avoid unnecessary drenching.

Dr Dean Revell from Revell Science in Western Australia was the keynote speaker at the Fodder Trees and Shrubs for Grazing Systems field day in Bywong. Over 35 farmers attended to learn about how native fodder trees and shrubs can be incorporated into livestock systems.
Dr Revell led a discussion about how fodder grazing systems using native shrubs combined with pasture can provide stock on small and large farms with feed during autumn and winter feed gaps (or any other time when the weather is being unkind). We learned that shrubs use ground water not accessible to grasses, bring nutrients to the surface for other plants to use and provide shade and shelter for grazing stock. Dr Revell also outlined the amazing ways in which stock learn to use fodder shrubs and how we can use animal behaviour to teach stock to eat new plants.
Grazing systems using shrubs also benefit animals by reducing stress caused by extremes in temperature, allowing the metabolic system of the animal to work efficiently which keeps growth rates steady. Some shrub species also provide medicinal value to the livestock thereby reducing worm burdens and potentially methane gas production. Farm productivity improves by reducing the cost of inputs including supplementary feed and drenches. It also allows farmers flexibility in rotating paddocks and feed resources. The downside to fodder crops is the initial start-up cost, but economic modelling over the long term showed improved grazing productivity.
Geoff Butler from Wamboin Gearys Gap Landcare was on hand to share his extensive knowledge on local plant species that could be suitable for fodder. He discussed the establishment of shelter belts and the importance of site preparation including ripping, time of planting and tube stock establishment. Establishing effective windbreaks can have many positive effects in farming systems in addition to slowing wind speeds at ground level including providing habitat for beneficial birds and insects, providing additional feed resources during drought (using fodder trees suitable for coppicing) and providing shade and shelter for stock.
South East Local Landcare Services Officer Matthew Lieschke gave a seasonal update and demonstrated how to calculate supplementary feeding rates for livestock if you do not have any fodder shrubs to fill the gap.
A key message from the field day is that incorporating native fodder shrubs into a grazing system can reduce the need to hand feed and that while stock are using the fodder shrub area, other pastures are able to recover better.
