INTRO: A Polish scientific breeding study shows that pigs are Mozart connoisseurs rather than budding metalheads. Nathan Frandino reports. STORY: Polish pigs are squeeling for Mozart. A new study by the Krakow University of Agriculture finds that when subjected to music these pigs are changing their behaviour. But it's the type of music that seems to matter most. Twice a day for 15 minutes scientists played Mozart for 30 pigs and melodic metal band "The Scorpions" for 30 other pigs. Dr. Monika Petrynka says it only took three days for the pigs to start behaving differently. (SOUNDBITE) (Polish) SCIENTIST AT KRAKOW UNIVERSITY OF AGRICULTURE, DR. MONIKA PETRYNKA, SAYING: "The first results are promising, because these animals spend more time having fun, which means that they are more satisfied that their welfare is better." Pigs already have highly developed senses, especially with hearing. After the first five months of research, it turned out that those listening to Mozart gained more weight than those who listened to the rock music. Dr. Jacek Nowicki says the research was intended for breeders as well as scientists. (SOUNDBITE) (Polish) SCIENTIST AT KRAKOW UNIVERSITY OF AGRICULTURE, DR. JACEK NOWICKI, SAYING: "If they have anything that somehow stimulates a positive, natural behaviour for these animals, it turns out that the production results are simply better." And for these happy hogs, that's music to their ears.
