L.EQT.2301 - MSA Saleyard Pathway Evaluation for Sheepmeat
Did you know that currently the MSA Sheepmeat model only allows direct consignment to be eligible for MSA? A saleyard pathway for sheepmeat would allow more animals to be eligible, resulting improved consumer satisfaction of lamb.

Summary
This project aimed to increase lamb eligibility for the MSA Sheepmeat model by evaluating the effects of selling methods on meat quality parameters of lamb. The project compared direct consignment with saleyard to slaughter and also included a saleyard combined with 5-day refeeding period, which has been aligned with industry regarding commercial practice and practicality.
Objectives
The overall aim was to determine the effects of saleyard consignment on lamb meat quality parameters including sensory evaluation at five days ageing of three cuts.
Direct consignment versus saleyard to slaughter was compared along with a saleyard (up to 48hrs) and five days refeeding treatments.
Investigation into the impact of longer ageing times (up to 50 days) on consumer sensory scores and microbial load analysis of high pHu carcases was also conducted.
Key findings
Given the impact of saleyard treatment groups, to protect the end consumer, it is recommended to apply a three-point adjustment to the MSA prediction of eating quality (restricted to 48 hours between farm and slaughter).
Extended ageing up to 70 days was significantly beneficial for all cuts, particularly for the topside cut, and this was not impacted by loin pH24 or pHu.
Benefits to industry
This research provides essential data to quantify the eating quality impact of lamb marketed according to different practices; direct consignment, through a saleyard, or through a saleyard with refeed.
Additionally, the study demonstrated that extended ageing improved eating quality, especially for tougher cuts like the topside.
MLA action
This online summary will be published on the MLA R&D website.
MSA Standards have been updated to include saleyard pathway for sheep. Fact sheet to be written.
Future research
Further research on extended ageing of all cuts beyond 21 days which is the current maximum limit in the MSA sheepmeat model, with and without electrical stimulation, to better understand ageing curves and the benefits of long ageing.
Further research should assess the economic and operational feasibility of refeeding compared to direct consignment for commercial settings.
