        They might mean the paint itself is abuse, which I think most vegans would agree with, but the more solid part is the abuse around owning either a commercial farm cow, or a research and testing cow.

        It is just a picture but its hard to assume this cow came in from the grassland asking for help with mosquitos, and we nice humans obliged.

          I think most vegans agree that factory farming is abusive. I would be interested to hear a case that the paint itself is abusive.

            It sort of gets into reducing the animals free will. It might not mind the paint but it also might not like it, and it can be hard to tell. There is also a good chance its toxic or causes some affect unintentionally.

            Usually the thing I’ll ask, is who is benefiting from this action? If its not the animal, it probably shouldnt be done.

            I think a good counter example is collars. My dog loves his collar because it means he’s going outside. It keeps him safe and others safe too. The collar is a good thing.

            Edit to add: I am by no means a great reference on veganism, just doing my best!

              Thanks, yeah that is an interesting point. I suppose any sort of experimentation becomes a bit more ethically dicey when the scientist can’t have informed consent from the subject.

                Theres also some debate over how useful it is to experiment or test products on animals from a scientific standpoint. I do think scientists understand more than most how gradual change can be though so maybe thats why its not as loud a conversation from them.

      Pedantic warning: it’s not a conventional function, cuz it’d be multivalued for any given input no matter where you put the axes lol

    I’m going on holiday to Cambodia in February. Guess I’ll bring my body paint supplies and run around in war stripes over my body.

    Interesting. A while ago, I read that zebra stripes were meant to confuse predators. Basically, the idea was that when they ran as a herd, their stripes made it difficult to tell where one zebra ended and the other began. I wonder if that’s considered bunk now or if this is supposed to be an additional benefit.

      Doesnt this study just imply that paint repels mosquitos? If they wanted to disprove that I don’t see why they wouldnt use black paint instead of what they did which was using black cows. If you paint a black cow black, and it gets bit less, that would sort of give it away wouldnt it?

        The treatments were black-and-white painted stripes, black painted stripes, and no stripes (all-black body surface). Recorded fly-repelling behaviors were head throw, ear beat, leg stamp, skin twitch, and tail flick. Photo images of the right side of each cow were taken using a commercial digital camera after every observation and biting flies on the body and each leg were counted from the photo images. Here we show that the numbers of biting flies on Japanese Black cows painted with black-and-white stripes were significantly lower than those on non-painted cows and cows painted only with black stripes

        The study says that zebra markings repels flies.

          It says at most that paint over skin will reduce mosquitos biting. Unless there is more expounded up in the study that was left out here.

        If you paint a black cow black, and it gets bit less, that would sort of give it away wouldnt it?

        They already did sorta do that. One of the three groups was painted black on black, albeit with stripes. Those were bitten as much as the unpainted black cows.

        To take it to the furthest conclusion I’d paint them entirely in black, and entirely in white (in case there’s something different between the white and black paint besides the color).

          Oh interesting I think I misread that middle group, I thought it was white stripes. I’ll have to go back over it when I have the time to look at the details. I agree with your last point though.

        Like other insects, I believe flies orient themselves with light. Striped surfaces like this would cause some confusion with that. There’s a few studies around about flight paths and light/surfaces around, if there’s any interest I’ll do a rummage. Light reflects, black absorbs remember. Very good for controlled contrast.

          I get its supposed to be a sort of camouflage, but the group that had the best results also happened to be the only one that had stripes and a full cover of paint.

          The one concern I have with the other types of tests is that I’m not sure flies are attracted to non-animal surfaces in the same way. But then again I don’t know the mechanism of how a fly targets where to go and then how it gets there navigationally.

      Wait wait wait, I’m calling bullshit. I see no udders, nor any horns. That’s obviously two people wearing a striped cow costume for Halloween, duh.
