Internal parasites can dramatically alter how an animal’s immune system functions, weakening its ability to respond to preventive health protocols like vaccinations.

In order to have healthy animals, producers must understand the normal health attributes of livestock, routinely monitor their animals and make management changes when necessary.

In 2017, a New Jersey farmer discovered a significant number of ticks that were only on his sheep. Neither the sheep nor its owner had traveled from the farm or had come in contact with other livestock. Experts are scrambling to learn more about this latest invasive species.

The best way to treat flies is to first understand what fly you are treating for. Remember: Face flies are found on the face, stable flies are found on front legs, and horn flies are found on the back and sides.
