Age of animals slaughtered

Last updated 12 October 2017

Most animals are slaughtered as babies, at a very small portion of their natural life span, regardless of whether they are raised conventionally or in operations that are labelled “humane”, “sustainable”, “natural”, “free range”, “cage free”, “heritage bred”, “grass fed”, “local” or “organic”.

  Typical Slaughter Age Natural Life Span
Chickens (male in egg industry) 1 day Up to 8 years
“Veal” calves 1-24 weeks 15-20 years
Chickens (broilers / meat breeds) 5-7 weeks Up to 8 years*
