The U.S. Agriculture Department on Friday suspended slaughtering operations at Catelli Brothers in Shrewsbury after determining the video documented two instances of inhumane treatment of animals that were to be slaughtered.
One cow had its neck slit and was bleeding profusely but was still conscious after being shot several times with a stun gun.
A calf was unable to walk, and was videotaped being dragged.
The Humane Society sent the video to federal officials. It calls the case "egregious."
The company promises to cooperate with the investigation, saying it is serious about its responsibility to handle animals humanely. It says it has hired a leading animal treatment expert.
