Queensland feeds algae to cattle

Queensland University has concluded its research on protein-rich microalgae which livestock farmers could feed to their cattle. The algae would significantly reduce costs and could be powered through solar energy, as well as save freshwater.

Sponsored by Meat and Livestock Australia, the study was conducted by Queensland University researchers at its Algae Energy Farm, an off-grid, 250,000 demonstration at the institution’s Pinjarra Hills campus.

Led by Peer Schenk, researchers were keen to develop a process that would not compete for arable land used by existing food production. The microalgae can be easily grown in the Australian climate even during drier seasons.

Although a timeline for the technology transfer has not been announced yet, the process is fully ready for on-site, large-scale commercialisation. It has a wide range of applications beyond feeding cattle, and could also be used as biofuel.

Peer Schenk said: “Microalgae would help with management of prolonged dry conditions, such as those affecting much of Queensland now. The challenge is to develop technology that can be readily and cost-effectively applied on beef properties as a homegrown source of high-quality protein feed.”
