Aerosmith frontman Steven Tyler is urging Massachusetts lawmakers to ensure the last journey pigs and cattle take on their way to slaughter is as comfortable as possible.

Following a performance in the state on Wednesday (16Jul14), the rocker called on officials to help improve the travelling conditions of breeding pigs and veal calves.

He says, "Massachusetts holds a very special place in my heart. Not only is it known for being ahead of the curve on important progressive issues, but it's also the birthplace of my band Aerosmith. That's why I was thrilled to learn from my friends at The Humane Society of the United States about S.2232, a critical bill that would ban the extreme confinement of animals used for food.

"Veal crates and gestation crates cause unspeakable suffering and with the success of crate-free environments, they are proven unnecessary. I hope to see the passage of S.2232 without delay."

The state legislature has two weeks to pass the new laws.
