Agricultural experts hope to use the sperm to fertilise pig eggs back on earth and monitor the effects of the journey to space.

The pigs chosen are a breed called Rongchang, named after an area in the southwest of the country and famed for their physique and for the quality of their meat.

Sun Laiyan, chief of the China National Space Administration, earlier told China Daily that Shenzhou VI will carry two men into orbit for five or six days.
