A new wave of concern is sweeping the Australian cattle industry as the damaging impact of continuing to use single-active drenches on cattle growth comes to light.
The consequences of widespread reliance on outdated technology are dire
On some occasions, cattle are becoming sick or dying due to blood loss and/or diarrhoea from uncontrolled worm burdens4. More commonly, recent research has shown that continuing to rely on single-active drenches will impact cattle growth, leading to significant economic loss. A look into three different trials that compares the use of single-active drenches versus more innovative combination drenches using multiple active ingredients show that not only are those drenches 99 to 100 per cent effective against key cattle worms, they also significantly maximise cattle growth1,2,3 affecting your bottom line.
By killing more worms, including those resistant to single active drenches, combination drenches not only enhance treatment efficacy but also play a crucial role in delaying the development of drench resistance, a growing threat to sustainable livestock production.
The message is clear: the era of single active drenches must come to an end
By embracing the new standard of combination drenches, Australian cattle producers can safeguard their investment, enhance their profitability, and also help the long-term sustainability of the industry.
