Feed efficiency measurement for better management

Beef Central, 11/06/2020

Lawsons Angus bulls lining up at Growsafe feed efficiency measurement stations.


VICTORIAN seedstock producer Harry Lawson is a fan of numbers, and what they tell him about his business.

It’s no surprise, as Lawson Angus – one of Australia’s largest cattle seedstock businesses – generates plenty of data.

“We’ve chosen to invest in technologies and systems which we see as beneficial to us in a management sense, and also to our clients from a genetics perspective,” Mr Lawson said.

One such tool is a data capture, management and decisions support program called GrowSafe.

The Lawsons have used GrowSafe systems since 2018 to accurately measure feed intake and average daily gain.

As well as a feed intake system, the technology’s GrowSafe Beef component records partial body weights every time cattle drink, providing real-time information.

Mr Lawson said he was ‘revved up’ about the ability of technology to deliver multiple weight readings throughout the day to create a more accurate picture of cattle performance.

“It gives us more accurate weights in a timely manner without having to run the pens through the yards each time we need to weigh them,” he said.

“If you run 40 bulls into the yards, some might have drunk 40–50 litres of water or eaten 20kg of feed just before they came in, which means you get a great variation in weight at any one time.”

The main reason the Lawsons have invested in the technology is to develop a system which not only accurately ranks animals for feed efficiency but also links to a global database, as the Canadian-developed program is used by research facilities.

“Most of the Angus sires which have feed efficiency data don’t meet our other multi-trait criteria, such as calving ease, mature cow weight and carcase traits,” Mr Lawson said.

The seedstock business has established its own bull testing and research and development centre to draw on GrowSafe’s software and analytics, to feed information into genetics research as well as provide valuable management information.

Mr Lawson said he also saw a place for the technology on-farm, with potential future use in conjunction with emerging technologies such as virtual fencing. He’s also interested in the practical applications of technologies which allow producers to manage large amounts of data.

For example, technology which collects real-time information about livestock can identify health issues.

“The system picks up bulls with reduced intake and/or lower average daily gain before clinical signs of ill‑health appear, so that way you can treat animals before the issue.

“Last year, we had a bull which lost 2kg a day for more than a week – this showed up in the data. When we looked at him, he had pink-eye so we could treat it and get him back on track.”

Wise investment

“Instead of just getting a weaning weight at the end of the year, with this system we’ll be able to fine-tune management throughout the year.

“I want to know what the minimum amount of grain is to meet my targets. If mixed grain is $450/tonne, then every kilogram variant is 45c/head/day, which is significant when feeding large numbers of cattle. I can vary my ration, feed more hay or silage, and I can find my answers accurately at least fortnightly.”

Lessons learned:

  • Look for options to incorporate technology into your business model, but don’t just focus on the cost of it – consider the impact of technology on people and management.
  • Don’t do things because you think they’re sexy – incorporate technological solutions which work for your business and will provide information to help you make decisions.
  • Technology provides leverage to engage the next generation of producers.

    Good work Harry , good data is critical as costs go up especially actual individual data . Nothing worse than seeing extrapolated data working on averages and assumptions

    Measuring “Feed Efficiency” incorrectly will never generate higher profits.
