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
Black paint was not as effective as black and white paint.
It did show in the results that black paint had a 15%/10% decrease or something around there though. Would that indicate anything? Another group done with white stripes and a fully painted white and black group I think would have helped but maybe there was good reason not to.
