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 US Food and Drug Administration (FDA) is updating information to beef cattle producers concerning a group of growth-promoting implant products (implants) that do not specify on the labeling whether reimplantation is approved. Three important developments must be considered by all cattle producers:

Spring is an appropriate time for tick education. Ticks may be active all year long if temperatures outside are above freezing, but May and June are the months when people pick up the most ticks. There are three tick species established in Nebraska that carry and spread diseases to humans and animals, including the lone star tick. Lone star ticks are widely distributed across the East, South and Central United States, extending across the southeastern portion of Nebraska (see figures at the end of the article).

Key Points

Nebraska’s spring weather conditions have made it more difficult to predict the emergence of horn flies. If the current weather pattern continues, we should start to see horn fly emergence in the southeast part of the state in early May, reaching northern Nebraska by late May. If we experience an abrupt and sustained warm-up, horn fly numbers could reach or exceed the Economic Injury Level (EIL) statewide by the end of May. The EIL represents a fly population of 200 flies per animal that negatively impacts cattle production enough to warrant paying for a fly control measure.

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.

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.
