Toxic bait aversions in different rat strains exposed to an acute rodenticide

Article Abstract:

A study of domesticated and wild rats exposed to food pellets containing the rodenticide, zinc phosphide, reveals that the rats develop bait aversion. The wild rats become more averse to the toxic bait than the domesticated rats. They recognize rodenticide pellets fast and seek food in a safer area. They remain averse to the bait for a longer time than do the domesticated rats. The difference in the behaviors of the wild and the domesticated rats may be caused by the difference in their sensitivity to taste.
