Animal production and livestock factsheets

This factsheet provides information on the requirements for keeping fallow and red deer species in Western Australia.

Fallow (Dama dama) and red deer (Cervus elaphus) are declared pests under the Biosecurity and Agriculture Management (BAM) Act 2007 in Western Australia (WA).

The department assists in preventing the establishment of deer in the wild. This means a permit is required to keep fallow and red deer in WA. Animals that escape or become feral must be recaptured or destroyed.

Small populations of feral deer occur in WA from escaped captive stock and deliberate release. Deer damage native plants, crops and plantation …

Wind Erosion Control After Fire In Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

First steps after a fire

Act to limit further erosion:

• Remove livestock and keep them off burnt paddocks: they can be put into a confinement feeding area, an unburnt paddock or agisted.

• Minimise vehicle traffic on burnt areas

• Protect highly susceptible and valuable areas, such as house, garden, sheds, yards, gateways and laneways with binding spray, clay, gravel, old hay, or straw to give a full cover. A dust-free living and working environment is particularly important after a fire.

Leave burnt residue on roadsides, revegetation and bush areas to decrease the risk of wind erosion.

Natural Revegetation And No Grazing, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

The department recommends that any dryland salinity management is part of a whole farm, and preferably a whole catchment, water management plan.

Natural revegetation and no grazing are only recommended for sites that are too saline, waterlogged and/or inundated for other treatments to succeed in the south-west of Western Australia. It is also the preferred option for the lowest possible cost.

Saltland Pastures In Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Saltland pastures are associations of salt and waterlogging-tolerant plants that produce fodder for grazing animals from saline and waterlogged soils. Saltland pastures can improve production from saltland sites, reduce salt movement from the site, and improve soil structure.

The Department of Primary Industries and Regional Development recommends that saltland management is part of a whole-farm, and preferably whole-catchment, plan.

Lupin Root Diseases - Diagnosis And Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Root, hypocotyl and stem base diseases can be significant problems in lupin crops, reducing stand density, plant vigour and yield. Root disease is present in nearly all narrow leafed lupin (Lupinus angustifolius) paddocks but in the majority of paddocks has only a small impact on crop development. However, in paddocks where high levels of root rot occurs, plant establishment, seedling vigour and crop yield can be significantly affected.

When a root disease is present in a crop very little can be done to manage it in that cropping season. It is therefore vital that the cause is correctly identified to …

Key Monitoring Times For The Ewe Flock, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

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

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 …

Cattle Performance Grazing Canola And Cereal Crops, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

The Department of Primary Industries and Regional Development conducted research to investigate and demonstrate the performance of cattle grazing canola and cereal compared to animals left on pasture and investigate the value of spelling the pasture during the time the cattle are grazing crops.

Cattle grazing cereal crops had a higher liveweight gain compared to the cattle that remained on the pasture. However to see a significant benefit from grazing dual purpose crops, the grazing period may need to be longer than 4 weeks particularly when grazing canola.

The highest growth rates for cattle grazing the cereal crops were achieved …

Pre-Plant Fertiliser For Brassica Crops On Loams, Department Of Primary Industries And Regional Development, Western Australia

Horticulture factsheets

Fertiliser is a major input cost in vegetable production along with labour and seedling costs. Optimising fertiliser rates and application methods is important to gain maximum benefit. The following information is based on trials carried out from 2008 to 2010 on broccoli and cauliflower crops grown in karri loams at Manjimup, about 300 kilometres south-west of Perth, Western Australia.

Trial results indicate that changes can be made to rates and application methods to optimise fertiliser use. Changes to application methods include strip incorporation of granular fertilisers and the potential for using liquid phosphorus for pre-transplant application.

Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

If correctly and appropriately undertaken, the destruction of rabbit warrens, or modification of the habitat so it becomes less favourable to rabbits, can be an important and effective part of reducing the impacts of rabbits.

Destruction of warrens can improve the overall effectiveness of rabbit control programs, even though many rabbits live and shelter above-ground under bushes, and in scrub). If undertaken properly, the ripping of rabbit warrens can often provide a relatively permanent and long-term benefit. Similarly, removing or modifying other forms of rabbit-harbourage (for example, removing rock piles) can help, particularly in semi-urban areas or on smallholdings.

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. …

Cotton In The Ord River Irrigation Area (Oria), Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Cotton has been grown very successfully in the Ord River Irrigation Area (ORIA) of Western Australia.

Cotton was grown commercially in the ORIA between 1964 and 1974. The early industry was subsidised by the Western Australian Government. The industry failed due to an inability to control major insect pests, and problems with quality. The industry never achieved economic yields, and short fibre length and discolouration resulted in substantial discounts.

Cotton has been the dominant irrigated crop in the ORIA since 2021. A cotton production system based on genetically modified varieties has been developed for the ORIA, based on intensive local …
