Do Cows Get Annoyed by Flies?

In a word- yes. Flies are a huge nuisance for your cows. Cows are absolutely irritated by fly feeding behavior. Because of this, they can become very stressed this time of year. They may also become restless and spend less time lying down when under heavy fly pressure. A prolonged exposure to this type of fly irritation can even lead to a decrease in production. In fact, Janna Block, Extension livestock systems specialist based at NDSU's Hettinger Research Extension Center. "Irritation caused by flies leads to behavior changes and can reduce the amount of time spent grazing, which can result in weight loss and decreased milk production. Additionally, flies are a factor in the transmission of diseases such as keratoconjunctivitis (pinkeye) and summer mastitis." 

How to Keep Flies Off Cows

Yes, flies are annoying to cows. More than that, flies are responsible for a significant amount of lost production, thanks to decreased weight gain or lower milk yields. You don't need to just let this happen, of course. You can battle the flies with through-feed.

JustiFLY is the solution you're looking for. Your cattle eat the mixture as feed, and it goes through their system. Eventually, it passes through the cow and sits in the field as manure. When flies try to lay eggs in the cow's dung, the insect growth regulator (IGR) larvicide prevents this. This breaks the life cycle, making female flies unable to lay eggs in the manure of the cows who have eaten it.
