The Ministry of Defence (MoD) has defended its use of more than 100 pigs in explosive tests in Wiltshire.
Some 119 pigs were used in the research at the Government's military research laboratory Porton Down, near Salisbury, between 2006 and 2009.
The tests "saved many lives" in Iraq and Afghanistan due to improvements in post-traumatic techniques, junior defence minister Quentin Davies said.
He said 25 pigs were used in 2006, 19 in 2007, 40 in 2008, and 35 in 2009.
