In September, the Animal Welfare Institute, a nonprofit that advocates for the animals, launched a new campaign called #SaveOurAnimals.
The hashtag has been retweeted more than 2.2 million times, with nearly 80 percent of the comments supporting the campaign.
But in recent weeks, animal advocates have begun to question the campaign’s credibility.
The Animal Welfare institute’s executive director, Carol Sorenson, is among those calling the hashtag’s popularity into question.
The #Save OurAnimals campaign is not based on the best available evidence, and its claims are not supported by any peer-reviewed research, Sorenkon said in a statement.
The group is now launching a new website, AnimalFarmsNow.org, to counter misinformation and promote the evidence behind its claims.
“It’s not only misleading and not grounded in science, it’s also completely false,” Sorenkin said.
Sorenkowski, who has worked as an animal advocate for decades, said the #SaveWeAnimals movement is a tactic that has no place in our society.
“This is a campaign designed to get more people to get out and vote, and that’s not a campaign to save animals,” she said.
“These are people who want to see their pet killed and not a group of people that wants to see it saved.”
In August, the Humane Society of the United States announced that it will spend $100,000 on ads to counter animal cruelty, as well as help the public identify the truth behind the #AnimalFarms Now campaign.
It has also launched a campaign that has been viewed more than 50 million times on YouTube.
“As a society, we need to take steps to ensure that animals have the best possible lives, and it’s imperative that we understand the real-world impact of our animal agriculture practices,” the Humane Kingdom Animal Legal Defense Fund, a group that is part of the Humane Action Committee, said in an email to NBC News.
“When you see people calling out a campaign, it is telling the truth, and we need people to know it.”
The Humane Society’s new website features a “factsheet” on the “cruelty” of factory farming, along with the hashtag #SaveAnimals, as part of a wider “factsheets” campaign.
According to the factsheets, animal cruelty is a serious problem in many U.S. communities, including the United Kingdom, Australia, and South Africa.
But many of the facts are misleading and lack sufficient detail, the group says.
“The Humane Society takes its mission of protecting animals and promoting responsible animal husbandry very seriously,” said Holly Pate, the organization’s vice president for research and policy.
“We take our research very seriously and we are working diligently to ensure we are using the most up-to-date science to support our message.”
According to a 2013 report by the Animal Legal Action Center, a non-profit advocacy organization, the U.K. is home to more than 4,500 factory farms, mostly in industrial settings, that are responsible for producing over 30 percent of all U.N. and EU animal products.
According of the report, these farms “have a far greater prevalence of serious abuses than the average U.I. farm.”
The report, which was published in April, also found that there are more than 60,000 U.V. farms in the United Arab Emirates and more than 500,000 in China.
The report also found the majority of the animals used in U.M.F. production are suffering abuse and are living in extreme poverty.
“Factory farms are the largest single source of the animal feed that goes into the U of A’s meat, milk, eggs, poultry and fish,” said Rachel Eller, senior director of animal advocacy for the Animal Rights Alliance, in a written statement.
“Millions of animals suffer from cruel living conditions, including beatings, confinement, starvation, pain and trauma, suffocation, dehydration, and inadequate medical care.”
