Spring hub

MLA has compiled this suite of resources, tips and tools to support your on-farm decision making during spring.

Pasture management

Key management practices in spring: Calculate | evaluate | plan ahead

Using hay and silage to remove annual grasses

Producers can reduce weeds and extend the life of established pastures by optimising hay and silage production this spring. Check out this free eLearning package to find out more.

EverGraze Feedbase Planning and Budgeting Tool

The EverGraze Feedbase Planning and Budgeting Tool is designed to help you to plan your rotational grazing systems, determine appropriate stocking rates, calculate your pasture growth rates, determine how long your paddocks will last and calculate the most economical ration for your stock. You can now also keep track of the carrying capacity (stocking rate) of each paddock by recording your dry sheep equivalent grazing days/ha. Maintenance fertiliser requirements can then be calculated.’

Stocking Rate Calculator

The Stocking Rate Calculator works out the monthly stocking rate in dry sheep equivalents per hectare (DSE/ha) throughout the year by adding together the stock numbers of each class and their DSE rating in a given month. This calculator is also available within the Feed Budget and Rotation Planner (see above).

Soil Phosphorus Tool

This tool is intended to assist P fertiliser decisions for temperate, legume-based pastures grazed by sheep and beef cattle on acid soils in southern Australia.

EverGraze Pasture Improvement Calculator

The EverGraze Pasture Improvement Calculator will help to work out the costs and benefits of resewing pastures. The tool allows inputs for costs of resewing, the benefits of the resewn pastures to livestock, soils and the environment at any given financial values (i.e. different interest rates, tax rates, gross margins etc).

MLA Cost of Production Calculator

The Cost of Production Calculator takes data on production, livestock enterprise costs, labour and overheads, and delivers both a ‘cost of production per kilo’ figure for the business and a picture of how it compares with other properties across Australia.

Key management practices in spring: Manage spring lambs | create genetic shopping lists | take on parasites

Co-investing in the industry’s future

SA sheep producer Anthony Pearce is well aware of the value of accurate genetic data, given his experiences as stud principal of Telpara Suffolk stud in Hartley, which sells a selection of high-performance rams and ewes each year.

Within his breeding operation, he concentrates on Australian Sheep Breeding Values (ASBVs) that increase growth traits while maintaining intramuscular fat, using the Terminal Carcase Production (TCP) index. For each, it’s important that he has reliable data to use and share with clients.

It’s the same story when he’s purchasing genetics, as he needs to know the ASBVs on rams he selects are accurate and that they are going to perform.

These are just two of the reasons why Anthony was motivated to co-invest in the satellite flocks as part of MLA Resource Flock project, contributing two rams of his own.

While progeny testing is expensive and also increases the generation interval, it gives a very high accuracy of ASBVs for the sires tested.

Along with submitting his own rams, as President of the Suffolk Sheep Society of Australia, Anthony also felt it important to let members know about the co-investment opportunity and encourage their participation to strengthen the breed.

“If you were to look at the reference populations of IMF alone in LAMBPLAN in August 2020, you’d have seen that there were 6,100 Poll Dorset animals contributing, but only 900 Suffolks,” Anthony said.

“We knew that we needed to build up our reference population, because the larger and more diversified it is for the carcase traits of interest to us, the more accurate it will be to underpin the use of genomics in Suffolk flocks.

“In late 2020, I approached our members calling for their involvement, and we saw a great response, being able to contribute two Suffolk eating quality satellite flocks to the project.”

Group effort

Anthony said the most important part of the project to convey to members was that participation wasn’t about individual success or finding the best ram, but about improving the overall quality of the breed through wider measurement of carcase traits on a diverse range of sires.

“We knew participating in the satellite flock wasn’t a profit-making exercise, but also understood that doing nothing to progress the genetics of our breed would be more costly overall than a short-term investment like this, which is why we got involved,” he said.

“In 2–5 years, there’s going to be an even greater requirement to produce lambs that have good eating quality, are high yielding and fast growing.

“A lot of the traits associated with these, like intramuscular fat for marbling, shear force, lean meat yield and carcase weight, are typically hard to measure and so are difficult to improve, but we have an opportunity to do so through the satellite flocks.

“The benefit of the project lies in this data, as it will underpin genomic prediction for Suffolks and ensure continued genetic progress so that we don’t get left behind by larger breeds of meat sheep.”

The Suffolk satellite flock completed data capture on their 2021 cohort by late December last year, with DNA samples and meat science traits collected on all project lambs.

Applying results

As a result of taking part in the trial, Anthony said he’s been motivated to make two key changes to his breeding program.
“We’re going to genomically test and verify the sires of all of our 2021 lambs to fast track the identification of elite performance sires and use these as ram lambs,” Anthony said.

“This has the additional benefit of ensuring the data we collect is high calibre and all our pedigree records are accurate.

“We’re also going to work closely with Elise Bowen (through the MLA Resource Flock project) to further develop our mating plan in 2022 and continue to use ASBVs as our primary selection tool as we believe taking a more scientific and data-driven approach will help us get the best performance from our flock.”

More Lambs More Profit

This MLA publication guides you through building lamb numbers through ewe management and increasing lamb survival.

Grass seed management

Grass seed infestation affects producers and processors through reduced growth rates in lambs and extra costs to processors. This page contains management options and strategies for keeping it under control.

Six steps to a lice‑free flock

Six practical tips to prevent and manage lice:

  1. Develop a lice biosecurity plan for your property. The LiceBoss website has guidelines.
  2. Use the Sheep Health Statement – if it shows there have been recent lice treatments, ask why. If the vendor is not prepared to tell you why they had to treat for lice, either discount the sheep heavily or don’t buy them. If possible, inspect sheep before purchase. When introducing sheep to your property, inspect, quarantine and monitor them.
  3. Monitor wool for signs of rubbing and fleece derangement. The LiceBoss website has a guide to monitoring sheep for lice.
  4. If lice are detected, consider your individual situation when selecting a treatment. Use the LiceBoss Treatment Guide to help with decisions such as:
    • what portion of your flock to treat
    • whether to do a premature shearing of all or part of the flock, followed by an off‑shears treatment
    • whether to do a long‑wool knockdown treatment to carry through to normal shearing time
    • which chemical group is most appropriate
    • how to respond if the infested sheep are pregnant or have lambs at foot
  5. The biggest contributor to lousicide efficacy failure is poor product application so make sure you’re doing it properly. The LiceBoss website has treatment guidelines for a range of applications, including back‑lining, dipping and jetting.
  6. Seek professional advice on treatment and control options and always inform your neighbours if you do find lice on your property.
