I came across this post supporting beheading a cattle for Eid al-Adha Festival:
Its states that KFC, McDonald's and Burger King kill about a billion animals each day.
Is this true?
According to this article on the number of animals saved by Vegetarians per year, there were 9,061,378,100 land animals slaughtered in the United States in 2013.
They compile this information from the USDA Poultry Slaughter 2013 Summary, the USDA Livestock Slaughter 2013 Summary, and this USDA Report on international meat trade for animals imported
The article itself is pro-vegetarian, so it has every reason to get as high a number as it can for its report.
9 billion animals may be a very large number, but divided by 365, it doesn't come anywhere close to 1 billion.
