  What if it’s just the white stripes (not the band)? Do white cows have the same number of flies? What if you paint them with black stripes?

  Maybe those are answered in the article, but I’ll never read it.

    LOL, same. Not worth the reading time. Any which way you twist it, there’s still probably way too many unknown factors.

  Yes. They had a control group with only black stripes along with an unpainted group. I would have to assume they also checked the paints for potential repellents, but I only skimmed the article.

    There is also the point creating a barrier.

      OK, but they didn’t count bites. They counted how many flies landed on the cow

    Instead of unpainted black they should have done painted black, or done both.

  I haven’t read the study, but most of these would need a placebo group, so divide the herd into thirds, one with no paint, one with stripes, and one fully painted white to get a baseline for each group. Also would be good to randomize which group each cow goes in each day so to rule out one cow who is especially tasty to flies.

    Also blindfold the scientists and the cows so it’s double blind. We don’t want the cows acting in a fly-attracting way because of placebo.

    Those groups also have another characteristic that changes: the amount of the cow covered in paint.

    How do you determine if its that vs the stripes or colors?

      You paint a second control group the colors and patterns they already are

        Did this study do that? The abstract didnt mention it.

  I’ve not seen the study referenced, but if I were doing it I’d have cows I painted with white paint, white stripes, black paint, and a control I left unpainted.

    Yes, obviously. But are the flies possibly repelled by the paint? Are the flies even able to bite through the paint?

      Somebody posted the study in this thread if you’re curious

        Fair enough. But I’m in no rush to paint myself or my dog, and I lost the last cow I ever had over the Rainbow Bridge…

    This study is posted in another comment here, but they left out the black paint group.

  A control group where they mix the colors together and paint them grey would answer that

    Can a biting fly even penetrate paint, to consume that precious bovine blood?

  What if you actually read the study before asking questions 😅😜🤔
