New findings from Meat & Livestock Australia (MLA) research indicate short duration lairage can maximize productivity for the grain fed supply chain. The duration of time and location where cattle are housed between arrival at an abattoir and slaughter is termed "lairage."
For Australian feedlot cattle, lairage duration is highly variable and can range between 2–36 hours, but more commonly ranges between 12–24 hours, and typically involves an overnight stay. Short duration lairage (SDL) of between three to four hours resulted in positive impacts on hot standard carcass weight (HSCW), hydration status and liver glycogen with no negative outcomes to meat quality and food safety parameters.
MLA engaged feedlot research scientist Dr. Melissa George of Bovine Dynamics to examine the effects of three lairage times at a grainfed supply chain in Queensland. Mid-fed export cattle were randomized to treatment and transported for 350km or 5.5h to the abattoir. The project was completed in 14 replicates including 2,226 individual animals to compare three durations of lairage including short (four hours), mid (16.5 hours), and long (26.5 hours) duration.
Study findings
This project demonstrated that reduced lairage duration provided a significant benefit in the profitability across the supply chain, as well as improved animal welfare and sustainability outcomes.
SDL of four hours or less was found to:
- yield a 7.4kg advantage in HSCW as compared to mid duration lairage
- yield a 6.2kg advantage in HSCW as compared to long duration lairage
- increase revenue by $40 to $48 per head assuming a $6.50/kg HSCW price
- results in similar food safety parameters to mid and long duration lairage
- increase hydration levels of cattle as evidenced by lower packed cell volumes
- increase liver glycogen compared to mid and long lairage duration treatments, an indication of improved energy stores, given their shorter duration off feed.
Logistics opportunities
Current MLA surveys indicate that short duration lairage was practiced on approximately 15% of the grain fed beef turnoff during the 2023 financial year. Given this, there is a large opportunity for increased revenue by adopting the practice.
To examine the feasibility of short duration lairage, MLA engaged Beattie Consulting Services and Richmond Hill Agribusiness to interview 27 stakeholders from across the grain fed beef supply chain.
