An animal researcher in Holland has claimed that the modern day pig's musical tastes have evolved over the last few decades, much like humans.
Unlike the human race, however, animals of the trottered variety still lag quite a way behind in their musical development.
Whereas the sounds most likely to feature on I-pods and mp3's will vary from trance to techno and indie, pigs are still very much hooked on the Seventies sounds of Mud, T Rex, Slade and Sweet.
Research carried out at the Hague Institute of Animal Behaviour suggests that pigs' enjoyment of glam rock played on large screens in their fields owes more to the glitter bedecked clothes and colourful make up the groups wore on their faces rather than the catchy sounds.
Our porkine cousins are sensitive to bright lights and being exposed to them for a period of time can see them becoming extremely animated and excited.
There is however no evidence to suggest that pigs' musical development will progress to the glam metal bands of Motley Crue and W.A.S.P.
