Stable flies aren’t just an annoyance. They cause reduced average daily gain, and it may take as few as four flies per leg to cause economic injury. Animals bunching to fight stable flies damage forage, and on fragile soils, may create blow outs.

According to the Center for Disease Control and Prevention (CDC), zoonotic diseases are pathogens that can be spread from animals to humans, leading to illness.  The CDC reported 59 zoonotic outbreaks in 2017, causing over 1500 illnesses and three reported deaths.  There are several different germs that have the potential to be zoonotic, with some more prevalent than others.  

The weather impacts producers right and left. A storm can come up suddenly and be short-term, whereas a drought can build and persist long-term. Stress can be similar in nature. We can have acute, stressful moments when we get into town too late to pick up that important part to fix equipment before chores the next day.  Stress can become chronic when one bad thing happens after the other. Many have experienced the effects of drought, first with not enough rain for pasture and forage production leaving us short and having to spend extra money to find additional hay or forage.

Insecticide-impregnated ear tags were first introduced in the late 1970s and have been used to reduce face fly and horn fly populations. Active ingredients in insecticide ear tags kill flies by direct contact. Small amounts of insecticide are released from the ear tag into the oils present on animal’s hair. The face, neck, topline and flanks receive the most product through natural grooming behavior. Interaction between cattle enhances the transfer of product between animals.
