Improving Lambing Rates And Changing Turnoff Times To Reduce Greenhouse Gas Emissions, Mandy Curnow, Sud Kharel, Claire Macleay

Animal production and livestock research reports

Running a flock of sheep and raising lambs generates both direct (enteric fermentation) and indirect (lime, fertiliser, fuel, production of feed) greenhouse gas (GHG) emissions. There are ways to reduce emissions through sheep reproduction.

The Impact Of Changing Joining Rates On The Western Australian Sheep Flock, Kate Pritchett

Animal production and livestock research reports

Given the poor seasonal conditions and low prices experienced in 2023/24, the Western Australian (WA) sheep industry is experiencing a period of very poor industry sentiment often compared to that seen in the 1990’s following the collapse of the wool reserve price scheme.

These difficult times mean producers have had to make production decisions for their businesses which may have flow on effects for the entire state flock. One commonly discussed option by industry and consultants was to join less ewes to reduce the feed burden on farm and help mitigate losses due to low prices. This computer modelling aimed …

Katanning Research Station Showcase: Projects And Initiatives, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock research reports

An overview of current projects run from Katanning Research Station.

Katanning Research Station is a sheep, pasture and cropping research hub. The digital agriculture technologies and management systems are designed to lift productivity and lower greenhouse gas emissions. The research includes the:

• genetics (breeding values) of feed intake efficiency in sheep
• impact of feed supplements and forage combinations on methane production of sheep
• evaluation of novel pasture species to develop livestock systems of green feed year round
• saltland rehabilitation program that aims to halt and reverse salinity (surface water management and groundwater drainage), and provide out-of-season feed (the planting of …

An Industry Life Cycle Assessment (Lca) For Sheep Production In Western Australia, Stephen Wiedemann, Darcia Mcrae, Emma Longworth

Animal production and livestock research reports

The Western Australian Department of Primary Industries and Regional Development (DPIRD) has identified the need to understand greenhouse gas (GHG) emissions from the livestock sector in detail, with a view to developing emission reduction plans for the state. To achieve this, DPIRD commissioned a life cycle assessment (LCA) for the sheep industry in Western Australia (WA) for the financial years (FY) 2005 (July 1, 2004 to June 30, 2005) and 2020 (July 1, 2019 to June 30, 2020). The analysis of one historic period provided a baseline reference point for the more recent results, and the intent was to develop …

Tracking The Wa Sheep Flock, Kate Pritchett, Mandy Curnow

Animal production and livestock research reports

The Western Australian (WA) sheep industry experienced a year of uncertainty in 2018 due to the disruptions experienced in the live export trade and the reported poor lambing season. This paper discusses the possible effect of these factors on the size and composition of the WA flock in 2019.

Implications Of Management Decisions On The Wa Sheep Flock In Response To Changing Markets, Kate Pritchett

Animal production and livestock research reports

The Western Australian (WA) sheep industry is profitable and productive and includes more than 4000 individual producers, processors and exporters as well as countless associated businesses and industries.

The industry makes a significant contribution to both the state’s agricultural production and the WA economy. In 2016/17 the gross value of agricultural production (GVAP) from the WA sheep industry totalled $1.4 billion. There is continuing demand for both wool and meat in export markets, giving strong incentives for increasing production of both wool and sheepmeat. This affords producers an opportunity to increase the productivity of their ewe flock and to grow …

The Impact Of Marking Rates, Turn-Off And Mortality Rates On The Wa Sheep Flock, Kate Pritchett

Animal production and livestock research reports

The Western Australian sheep flock peaked at 38.4 million head in 1990. Following the collapse of the reserve price scheme for wool and subsequent low prices combined with improved returns for crops, the WA flock entered a period of decline. The WA flock had fallen to approximately 14.2 million at the beginning of 2016/17. The dramatically reduced flock has also undergone a change in structure over this time, with the proportion of wethers in the flock being reduced from 32% of the flock to around 7%, and the proportion of breeding ewes increasing to accommodate the increased importance of lamb …

Marking Rate Scenarios For The Wa Sheep Flock, Kate Pritchett

Animal production and livestock research reports

The Western Australian sheep flock has been in a state of decline since 1990 when it peaked at 38.4 million head. As of mid-2016 the flock has reached a low of 13.9 million total sheep and lambs.
