Charles Sturt University (CSU) research has found canola meal may provide an option for beef producers to supplementary feed steers and still access premium prices for grass-fed beef.
The research through the Graham Centre for Agricultural Innovation has evaluated the growth rates of steers fed a supplementary ration of canola meal, a by-product of oil production.
CSU lecturer in the School of Animal and Veterinary Sciences Michael Campbell said one of the challenges of a grass-fed beef production system is filling the feed gap when there’s poor pasture growth and quality.
“Canola meal is palatable, cost effective and readily available throughout the NSW Riverina so we wanted to find out how it compares with traditional supplements like grain pellets, and a wheat and cottonseed mix,” Dr Campbell said.
“The advantage of using canola meal, rather than supplementary feeding with a traditional finishing grain diet, is that producers can still meet the PCAS guidelines and tap into price premiums.”

The Graham Centre has supported two separate trials using canola meal by CSU Bachelor of Animal Science (Honours) students , Emma Lynch in 2017 and Jessica Hardie in 2018. Ms Hardie’s 28-day trial compared the growth rates of 160 steers fed poor quality silage.
The 80 steers were given a supplementary ration of canola meal and 80 were fed a supplementary ration of wheat and cottonseed.
- As the trial progressed the average daily growth rate was higher in the steers fed canola meal compared with steers fed wheat and cottonseed.
- There was a higher gross margin per steer for those fed canola meal.
- The canola meal fed steers had a low feed conversion ratio or higher feed efficiency.
This builds on the results of a 60-day trial conducted by Ms Lynch in 2017 which compared 20 steers fed a supplementary ration of canola meal with 20 steers fed a grain pellet while fed poor quality pasture.
