Sows are still confined in farrowing crates when they give birth, and the piglets and fattening pigs are still kept intensively. Selective breeding Cows have been selectively bred to produce more milk. Broiler chickens have been bred to grow meat faster.

Lameness is very common amongst dairy cows.
