The CarLA Saliva Test has been developed by AgResearch scientists as a powerful new tool for selecting sheep with greater immunity to internal parasites.

What we do

The test provides an accurate and simple way to select animals which suffer less from the effects of parasitic worms, and which pass fewer worm eggs onto pasture. The test measures antibodies against worm larvae in sheep saliva: animals with high levels of antibodies are better at preventing worms establishing in the gut. This means the animals can put more of their energy into growth – without any increase in dags.

The CARLA Saliva test was developed by AgResearch Animal Health, with funding from Ovita, a joint venture between AgResearch Ltd. and Beef + Lamb New Zealand.
