Why Choose DRL Testing Services

DRL provides diagnostic services for farmers seeking to manage Johne’s in their herds and minimise production losses arising from Johne’s
In addition to conventional tests such as blood or milk, DRL uniquely provide a quantitative DNA test to determine MAP shedding levels in dung samples. This is especially useful for stratifying infected animals according to shedding risk.
Different animals have different levels of contamination. DRL tests identify individual carriers and quantify risk level to your herd allowing for targeted stock management.
The team at DRL is highly motivated to deliver a premium and cost effective diagnostic package, to give farmers the most useful information for the least cost.

Dairy Cows & Cattle

Johne’s disease is chronic, progressive, contagious and widespread with no treatment and no cure. It can however, be managed cost effectively.Read more

Small Ruminants & Alpaca

All ruminant species are susceptible to Johne’s disease, a bacterial infection which results in inflammation and thickening of the intestines leading to reduced uptake of nutrients and progressive weight loss. Alpaca are also a natural host for Johne’s disease that can be tested for bacterial shedding by DRL.Read more

"We started testing our replacement in calf R2 hinds as we knew we had a Johne’s issue. With six years of testing with DRL we were down to 1% positives, production was up and there were no visible signs of sickness anymore."
Robert Peacock, Orari Gorge station
"Peel Forest Estate has worked with DRL over many years on developing Johne's Resilience in red deer for the industry. DRL's dedication, professionalism, tireless analytical work and research has resulted in a very successful outcome."
