The People for the Ethical Treatment of Animals is criticizing the Bureau of Land Management for apparently euthanizing an unknown number of cattle at the Bundy Ranch.

“These animals shouldn’t be killed either by the government, or by the rancher who plans to send the cows off to slaughter. The best thing anyone can do to stop the suffering of animals is to go vegan,” PETA’s Senior Vice President Lisa Lange said in a written statement to Breitbart News.

The Bundy Ranch Facebook Page, run by Cliven Bundy’s daughter Bailey Bundy Logue, posted photos on Saturday night of a mass grave of their livestock found in a large hole in the ground on the land where the BLM was impounding Bundy’s cattle.

“This is unjust,” the Bundy Ranch said in a statement on their Facebook page Saturday. “Understand that this is beyond the cattle and it is overall about freedom but this is one of many incidents where the corrupt and unjust government is taking away our freedom little by little.”

The Bundy family has refused to stop allowing their cattle to graze on federally-owned land, saying the federal government does not have any authority over them. The impasse led to a tense standoff last-week in which both federal agents and Bundy supporters had sniper rifles trained on each others. The government ultimately backed down, at least for now.

Nevada Republican Assemblywoman Michele Fiore told Breitbart News on Friday that the treatment of the cattle by the BLM is “cruel” and she has heard from ranchers across the state with similar experiences with the BLM and its livestock seizure practices.

The deaths to the herd could have a serious financial impact on the ranch. Cliven Bundy told FOX News last week that one cow could go for as much as $2200 at market.

The impoundment of Bundy’s cattle happened during calving season and as a result, left a number of Bundy’s calfs without mothers. Bundy Ranch also posted photos of calfs who finally received milk.
