Pork - Piglets are taken away from their mothers at an early age (2-3 weeks). As a result, many die right then. When they are about 5 months old, they are slaughtered. For perspective, a pig’s natural lifespan is about 15 years.
Chicken - Chickens are sometimes slaughtered as young as three weeks of age. By 14 weeks of age, nearly all chickens (caged as well as “free-range”) are slaughtered. Naturally, they’d live much longer, up to 10 years.
Turkey - Turkeys are usually slaughtered at between 12-26 weeks of age. Their natural lifespan is 10-12 years.
Beef - Dairy cows are often slaughtered at about four years, sometimes while pregnant. Beef cattle are normally slaughtered between 9 and 14 months of age. The average lifespan for a cow or bull is about 15 years - some can live to 25.
Lamb - Lamb comes from baby sheep under the age of one year. Baby Lamb or hothouse lamb is slaughtered at between 6 and 8 weeks of age and Spring lamb between 3 and 5 months of age. Sheep can naturally live up to the age of 15 years.
Veal and Dairy - Veal comes from dead calves. The babies are a byproduct of the dairy industry. If people stopped drinking milk, veal production would likely end.
Eggs - The male chicks in the egg industry are useless and so they are usually killed as babies. Often they are ground up alive, sometimes they are gassed, and other times they are smothered by each other when they’re tossed into garbage bins.
