When you look at the picture of a furry pig that resembles a sheep from a distance, you may think that this may be the result of the work of some crazy scientist that tinkered with the pig’s genome. However, in this case, this is not true. Mangalica is a natural breed of pigs, which were bred in Europe for their lard. This breed of pigs is very unique, since the only other breed of pigs which had a long coat was Loncolnshire Curly Coat, which is now extinct. In the past, these pigs were quite popular, since they were able to produce a lot of lard. However, when the demand for pig lard dwindled, the population of these pigs rapidly decreased, making it a “rare breed”.
