Tips to improve MSA compliance for New South Wales producers

03 March 2020

The 2019 Australian Beef Eating Quality Insights report has revealed that average MSA non-compliance for New South Wales producers throughout 2017-19 was 5%, peaking in March 2019 at 7% as a result of high pH, which is meat pH greater than 5.70.

MSA Producer Engagement Officer, Laura Garland, said there were some key areas that producers can target to address pH and improve MSA compliance.

“Ultimate pH is heavily influenced by on-farm practices and there are two major components to this - nutrition and stress,” Ms Garland said.

“Carcase pH levels are driven by muscle glycogen, which is built up through good nutrition and then depleted by stress and exercise.

“To address issues of non-compliance to pH, producers need to maximise the amount of glycogen at the point of slaughter by optimising nutrition and minimising stress.”

Ms Garland encouraged producers to look carefully at their production systems to identify what might be contributing to issues of high pH.

“Given the drought conditions across large parts of the NSW east coast, and short supply of feed available feed, supplementing cattle with other nutritious feed sources will help to optimise their performance,” she said.

“Ensuring that cattle are achieving growth rates of at least 0.9kg/day will help to reduce the risk of dark cutting. When cattle are gaining weight at these growth rates and above, their muscle glycogen will be ‘full’, allowing them to cope with stressors like handling, exercise and transport and still have enough stored glycogen at the point of slaughter.

“A high-energy ration for at least 30 days before slaughter can increase muscle glycogen and reduce the risk of dark cutting.

“An animal’s energy requirements will also vary according to conditions – cattle might use more energy to stay warm on a cold day.”

Ms Garland said producers should also assess their cattle management in the lead up to slaughter to identify potential stressors and consider the following tips:

  • muster and handle stock as quietly and efficiently as possible
  • familiarise animals to handling and train stock persons in handling skills
  • maintain animals in their social groups - don’t mix mobs within 14 days of dispatch
  • ensure livestock have access to water at all times prior to consignment.
