A study conducted at Krakow University of Agriculture shows that pigs grow fatter when listening to Mozart music in comparison to pigs listening to symphonic versions of pieces by The Scorpions.
Although the exact reasons for this preference are unknown, the researchers could show a clear differences in behavior between the two groups of pigs. It turns out that the pigs listening to compositions by Mozart were more relaxed and spent more time playing or having fun, according to Monika Petrynka, a PhD student involved in the study. As a result these pigs gained more weight. The time will show whether these findings will be used in practice to increase well being of farm pigs.
