Sheep Worm Control In Wa, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Sheep Worm Control In Wa, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Effective, sustainable control of sheep worms involves a combination of planned stock and farm management, monitoring worm burdens using faecal worm egg counts (WEC), strategic timing of drenches and the genetic selection of worm resistant sheep.

Levels of drench resistance of sheep worms in WA are some of the highest in the world and without resistance management action at individual farm level, it will continue to worsen and spread.

Although effective drench options are generally available, many sheep owners are unaware that resistance has reduced the effectiveness of worm control programs, and this can affect profitable sheep production.


Early Weaning Of Lambs In A Poor Season, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Early Weaning Of Lambs In A Poor Season, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

The feed requirements of a ewe with a lamb at foot are higher than if the ewe and lambs are fed separately. In a difficult season with short feed supplies, it is better to early-wean lambs from their mothers to lower feed costs and ensure that the ewes regain condition before joining. This issue becomes even more important as the costs of feeds increase.

Ewe's milk provides the main source of nutrition for lambs until about eight weeks of age. Lambs will sample pasture from about two weeks after birth but by eight weeks of age pasture overtakes milk as …


Sheep Lice Spread And Detection, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Sheep Lice Spread And Detection, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

The most common lice affecting sheep are body lice (Bovicola ovis).

Knowledge of the lice life cycle and relevant features of their biology assist in our understanding of how lice survive and spread.

Better understanding and ability to find and monitor lice populations will improve sheep farmer decision making around eradicating lice.

Knowledge of when an infestation may have occurred, or alternatively that lice was not eradicated at the last shearing, is important information that will assist future treatment decisions.

Opportunities Using Eid – Tahara Case Study, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Starting from 2025, Electronic Identification (EID) will become mandatory in Western Australia. This requirement might cause some farmers to focus solely on the increased costs, potentially overlooking the opportunities these systems can bring to their farms. Clayton South, who manages his property ‘Tahara’ near Wagin in the Great Southern region of WA, operates a farm with approximately 4,000 Dohne ewes. They started using EID in 2014.


Guide To Supplementary Feeding And Budgeting, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Guide To Supplementary Feeding And Budgeting, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Supplementary feeding of sheep, with grain, hay or silage is necessary when pastures or stubbles are deficient in energy and protein.

A good supplementary feeding program will ensure sheep utilise as much dry paddock feed as possible as well as provide sufficient supplementary feed for maintenance or growth.

The Department of Primary Industries and Regional Development recommends supplementary or confined paddock feeding to maintain livestock productivity and avoid animal welfare and soil erosion problems.

To ensure sheep are in the right condition at the right time, they should be frequently monitored and their nutrition adjusted throughout the year. Frequent monitoring is especially important at times of drought, or at the change of season when paddock condition can change rapidly.


Time Of Lambing, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Time Of Lambing, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Choosing the best time of lambing, and matching paddock feed availability to ewe and weaner needs is important for both productivity and profitability. The ewes' natural breeding season will also affect reproductive rates. The ewe flock is the key flock on the farm, so it is important to set up a system that matches their needs with the feedbase. A ewe’s condition will vary over the season depending on the feed available and her needs. A ewe’s energy needs will double in late pregnancy and triple in lactation. Having enough feed to meet her changing needs is important for production …


Confined Paddock Feeding And Feedlotting Of Sheep, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Confined Paddock Feeding And Feedlotting Of Sheep, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Confinement feeding (also referred to as lot feeding or feedlotting) is an intensive feeding system in a confined area where all, or the majority of, feed and water is supplied to the contained animals. The department recommends using confinement feeding as part of a whole farm livestock, pasture and erosion management program.

We recommend having a confinement feeding system as an integral part of a whole farm livestock, pasture and erosion management program. Guides and resources that provide more detailed information are listed at the bottom of this fact sheet.


Barber’S Pole Worm In Sheep, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Barber’S Pole Worm In Sheep, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Barber's pole worm (Haemonchus contortus) is a potentially harmful roundworm parasite of sheep which can cause a disease called haemonchosis. It is mainly found in coastal and high rainfall areas of Western Australia.

In some cases large worm burdens can develop very rapidly and cause sheep deaths without warning. Whether specific pre-emptive action for barber's pole worm is needed depends on the risk level.


Sheep Feed Value Guide, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Sheep Feed Value Guide, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Sheep are supplementary fed for either survival or production purposes. Efficient supplementary feeding should aim to supply sheep with a diet that is sufficient in digestible energy and protein. We recommend testing feedstuffs, although the feed tables supplied here can be used to help roughly estimate the amount of grain and fodder required.

Knowing the value of different feedstuffs is critical when making decisions about livestock nutrition, for survival, maintenance and growth.

Supplementary feeding is a key part of a Western Australian (WA) sheep enterprise because most sheep systems are on annual pasture which is dry over the Mediterranean summer. …

Animal production and livestock factsheets

This analysis was prepared for the Department of Primary Industries and Regional Development’s Sheep Industry Business Innovation project by the Farming Systems Analysis Service in July 2017.

Provisos for the following:

  1. The price of sheep doesn’t reduce substantially over the next 12 months. This is not expected but it is a risk and therefore selling low priority stock is recommended. Low priority sheep are: dry sheep, wether weaners and old ewes >6yo.
  2. That confinement feeding is done with reasonable technical skill and that feed isn’t wasted and that animals don’t die at high rates


Breeding Ewes Are Worth Feeding, Department Of Primary Industries And Regional Development, Western Australia Sep 2024

Breeding Ewes Are Worth Feeding, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Despite potentially elevated grain prices, strong prices for meat and wool mean that Western Australian sheep farmers can confidently supplementary feed their underweight ewes in summer/autumn.

Analysis in 2019, based on then-current prices, showed it was a profitable investment to feed all ewes to maintain condition during pregnancy, and to feed low condition score single bearing ewes and low and medium condition score twin bearing ewes to gain condition.

In 2019, John Young from Farming Systems Analysis Service completed an analysis on the value of a ewe in the WA farming system. His report had some important messages for the …


Testing Feed Is Vital For Feed Budgeting, Department Of Primary Industries And Regional Development, Western Australia Sep 2024

Testing Feed Is Vital For Feed Budgeting, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

A little knowledge of the nutritional value of your supplementary feeds can save you a lot of money and hassle.

In dry seasons, it is likely that farmers will need to start supplementary feeding earlier than usual. The higher requirement for supplementary feeds over dry seasons means accurate feed budgeting becomes increasingly important to minimise feed wastage, for weaner survival, and to maintain stock at the right condition score (CS) for joining.

Condition Scoring Of Sheep, Department Of Primary Industries And Regional Development, Western Australia May 2024

Condition Scoring Of Sheep, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Condition scoring sheep is an easy and accurate method of estimating the condition or 'nutritional wellbeing' of your sheep flock. It requires an assessment of the amount of muscle and fat covering the backbone and the short ribs of each sheep. This gives a picture of the sheep’s store of energy. It is the best method for monitoring pregnant and lactating ewes but is also useful for monitoring the growth of weaners.

Joining - Setting The Potential Of Your Ewe Flock, Department Of Primary Industries And Regional Development, Western Australia Jan 2024

Joining - Setting The Potential Of Your Ewe Flock, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Joining is the time when the potential lambing of your flock is set, so make the most of it.

Preparation of ewes and rams for joining should start 8 weeks prior to joining for the greatest benefit.

Key tactical decisions around ewe and ram health and nutrition should be made prior to joining. This should ideally start 8 weeks before joining as the impact of nutrition, shearing and teasing take time to influence joining success.

The majority of the ewes in Western Australia are seasonal breeders. The spontaneous cycling in Merinos and breeds such as Poll Dorset are least affected …


Sheep Worms – Sustainable Summer-Autumn Worm Control, Department Of Primary Industries And Regional Development, Western Australia Jul 2023

Sheep Worms – Sustainable Summer-Autumn Worm Control, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

A summer drenching program for sheep worm control is now recognised as a key cause of drench resistance in Western Australia. However, some small changes can increase the sustainability of pre-emptive control programs. Drenches in summer should always be given to younger, growing sheep (current and previous year’s age groups), whereas adult sheep should be drenched in autumn, or if drenched in summer, some should be left untreated (if drenching at all). Research shows that this reduces the chance of developing drench resistance but still provides effective worm control.


Best Practice Marking Of Lambs, Department Of Primary Industries And Regional Development, Western Australia Mar 2023

Best Practice Marking Of Lambs, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Lambs should be marked between two and 12 weeks of age, with the youngest animal in the mob at least 24 hours old, to ensure the formation of a maternal bond. If lambing extends for more than six weeks, consider having two mulesing/marking sessions.

Lambs should be tail docked using a gas-heated knife or rubber rings and mulesing should only be carried out when necessary.

The provision of pain relief with routine husbandry procedures benefits animal health and welfare and is now a consumer and community expectation. Producers have access to registered products that can relieve pain associated with mulesing, …

Sheep Weaning Best Practice, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Monitoring the health and liveweight of weaners is important to ensure their survival and for producers to maximise profit. Weaners are more susceptible than adult sheep to a number of health issues, as their immune system is still in development. Vaccination, drenching for worms and flystrike control are important management steps at weaning.


Growing Weaner Sheep, Department Of Primary Industries And Regional Development, Western Australia Jul 2019

Growing Weaner Sheep, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Weaners are the most difficult class of sheep to manage effectively, largely because they usually cannot consume enough energy while grazing dry pastures and crop stubbles.

There are a number of techniques you can apply to ensure your weaners are effectively managed, including setting and meeting growth targets, being vigilant on health and disease management and ensuring the weaners have their protein and energy needs met.


Lambing And Lactation, Department Of Primary Industries And Regional Development, Western Australia Dec 2018

Lambing And Lactation, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

The first 48 hours of a lamb’s life are critical – around 90% of lamb mortality from birth to weaning occurs within this period. It is also a critical period of time for the ewe. She is at risk during birth, has her highest demand for food and is vulnerable to sudden changes in diet and conditions.
