Adapting Dairy Farm Systems

The project aims to provide economic and risk analysis for intensive feed systems in the dairy industry. It is funded by Dairy Australia, Agriculture Victoria, NSW DPI, and DairyUP. The goal is to assist farmers in making informed decisions when transitioning to new feeding and housing systems.

Dairy feed production systems vary based on the proportion of pasture and supplementary feed in the diet, and these choices are influenced by farm managers' goals, available resources, and the adoption of new technology and management practices. 

Due to factors like irrigation water availability, water price, pasture growth variability, and persistence, dairy farm systems are shifting towards more complex combinations of feedbase, feed delivery, and herd management, including cattle housing systems. 

The economic aspect of the project involves using farm data to validate assumptions about feeding a total mixed ration (TMR) and understand the factors contributing to the profitability of the new system. The data from selected TMR farms in different states will be aggregated and used to create a framework to support dairy farmers undergoing or considering a feeding system change.

The second edition of the National Guidelines for Dairy Feedpads and Contained Housing has been developed collaboratively in partnership with Agriculture Victoria. The guidelines are the first of their kind anywhere in the world and are an invaluable resource for farmers across all Australian dairy regions when making decisions around feeding and housing solutions for their herds.

They are based on global best practice, underpinned by published research and engineering standards, and reflective of current Australian statutory and regulatory planning.

The guidelines were written by a team of 21 subject matter experts from around Australia and the world.

Farm System Evaluator is an online tool that enables farm business performance to be assessed across key management areas. The tool uncovers the benefits and limitations of operating a new feeding and housing infrastructure that may suit specific on-farm needs. It also develops a strategic action plan to help farmers visualise a proposed feeding and housing infrastructure change.

AT A GLANCE:

• Scott & Anna Fitzgerald | Tongala, Victoria
• 460 cows | 108 ha
• Purchasing a mixer wagon
• PMR transitioning to TMR
• Summary
  With an increase in cow numbers and changes in water availability, the Fitzgeralds have considered alternative options for their feedbase. The Fitzgeralds purchased a 50 ha outblock in 2018 and installed a 28 ha centre pivot and planned to grow fodder. However, as water price and water availability became less reliable and the cows were being 100 per cent hand fed they needed to review their feeding infrastructure. This case study follows the transition of their business from feeding maize silage and vetch hay, to building a gravel feedpad and purchasing a mixer wagon.

AT A GLANCE:

• Colin, Karen, Chris & Ashleigh Gamble | Bamawm, Victoria
• 400 cows
• Building a concrete feed pad
• PMR, cattle graze pasture & crops
• Summary
  The Gamble Family have traditionally run a perennial pasture-based system on their dairy farm. With the escalation in water and feed prices in 2015, the Gambles first leased a mixer wagon in November 2015 and then purchased their own 3 months later. Seeing the results from the introduction of the mixer wagon the Gambles decided to make a system change and have since constructed a concrete fed pad to accommodate 400 cows with loafing areas. This case study describes their system change.

AT A GLANCE:

• Mark, Ann & Jacob Gardiner | Bamawm, Victoria
• 900 cows | 300 ha
• Purchasing a mixer wagon & concrete troughs
• PMR, cattle graze pasture & crops
• Summary
  The Gardiner Family have traditionally managed a highly profitable grazing system with perennial ryegrass the major component of the feedbase supplemented with concentrates and silage or hay. Tighter seasonal allocations of water and rising water prices in 2019-20 season ruled out irrigating perennial ryegrass over summer compared to purchasing in forages leading the Gardiners to think about a system change to mitigate the current operating environment. Importantly, this change needed to allow them to switch back to a perennial pasture-based system again when water prices make it economical.

AT A GLANCE:

• Simon Rea | Naringal, Victoria
• 560 cows | 225 ha + 100 ha support area
• Clear roofed compost shelter
• Summary
  The Rea's built the clear roofed compost shelter to help shelter cows during winter and protect pastures from damage during wet conditions. It also helps to keep cows cooler during the summer. Learn more about the cost of construction, shelter management and operation and benefits to their farming system.

AT A GLANCE:

• Ray Smith | Yarrimbah, NSW
• 750 cows | 4,000 ha wheat/canola cropping & dairy farm
• Double sided compost barn
• PMR, cattle graze pasture & crops
• Summary
  The Smith's supply milk all year round with their herd averaging 10,000 litres/cow/year. The shelter was built to improve cow comfort and cow health both in summer and winter. The cows graze most of the year and utilise the barn at night time. The barn allows better maintenance of winter pasture and improves pasture utilisation.

AT A GLANCE:

• The Bourke Family Farm | Gladfield, Queensland
• 560 cows | 486 ha + 100 ha support area
• Double compost barns
• PMR in winter & TMR in summer
• Summary
  The Bourke family supply milk all year round milking twice-a-day. They grow their own feed including corn, barley and ryegrass silage and hay. The compost barns were built mainly to allow easy management of cows during wet weather as well as for cows cooling during hot weather. Since building the barns cow management is easier and milk production is more stable.

AT A GLANCE:

• The Garratt Family Farm | Southbrook, Queensland
• 230 cows | 535 (245 ha cropping country, balance bush)
• Narrow compost shelter with feedpad, open feed bunk and dry lot
• PMR in winter & TMR in summer
• Summary
  The Garratt family supply milk all year round and grow all their own feed, making silage from forage sorghum and barley as it is too dry to reliably grow corn. Due to herd growth, the feeding system has changed to less grazing and more time on the feed pad accessing a TMR. This has added to cow management issues, especially herd health, heat stress and wet weather management. Building a roof over the feedpad and later expanding the roof to incorporate compost bedding loafing area solved the herd health issue and minimised exposure to weather.

AT A GLANCE:

• By Dr Philip Chamberlain | Subtropical Dairy
• Bedding Pack Shelters (including compost bedding packs)
• Summary
  This information was collected from twelve dairy farmers in Queensland, Southern NSW and Victoria, who have built, and are now managing bedding pack systems. A review of literature has been conducted and highlighted information mainly from USA, Britain, Holland and Israel, much of which is relevant to Australian conditions. This is not a scientific paper, this document summarises Australian farmers' experiences as well as their issues, limitations and management requirements.

AT A GLANCE:

• Rachael Parkes & Ged Mullins | Ellangowan, Queensland
• 1,000 cows | 1,040 ha (800 ha leased)
• Dry lot with roofed shelters
• TMR, mostly from contract purchased feed
• Summary
  Rachael and Ged run a mixed breed commercial herd which are fed a TMR. They use drylots with roofed shelters for the milking herd to mitigate heat stress in summer, provide better cow comfort and gain a subsequent increase in cow health and production. This system works well in their relatively dry environment and are working towards have all classes of stock housed on dry lots with roofed shelters in the future.

AT A GLANCE:

• The Scheuerle Family Farm | Kulpi, Queensland
• 300 cows |
• Barn & dry lot
• TMR
• Summary
  The Scheuerle family farm feed a TMR based on sorghum silage and winter crop hay. Shelter was built to shelter the herd from heat in summer and occasional extreme wet conditions and to provide better cow comfort and cow health.

AT A GLANCE:

• David & Robyn Kuck | Tongala, Victoria
• 450 cows | 980 ha (includes 274 ha leased land) | No irrigation
• Operating an intensive farm system - drylot
• TMR
• Summary
  The Kuck's run a TMR system. They purchase grain and by-products when the opportunity is favourable. They aim to grow all the fodder required however, will purchase silage/ha if a good opportunity arises. The focus of their fodder production is to generate a large quantity of silage and then balance the ration with the grain and by-products. They predominately grow sorghum as it is difficult to grow high quality pastures in their region without irrigation. In this case study the Kuck's share several take home messages and offer advice to new entrants considering this type of system.
