The feed crisis also has its impact on visitor numbers at the 2012 edition of the PorkExpo, held 26-28 September in Curitiba, Paraná, Brazil.
The event, combining a trade show with the Sixth International Forum on Swine Production, attracted about 2,000 visitors on the first day. The organisers said that the total aim of the show would be to attract about 10,000 visitors.
This is significantly less than previous editions. Very high feed prices, due to a higher demand from the USA, cause many producers to stay away or reconsider their future.
The first day offered a host of different activities, as can be seen in this photo gallery.
