What is the purpose of slaughter house?

Semi trucks as well as individuals deliver animals to the slaughterhouse and place them into a holding area, usually the night before slaughter. Typically, the slaughterhouse processes one type of animal during a workday. For example, cows and steers are brought in on certain days and pigs on another day. This procedure enables equipment changes as well as necessary sanitizing procedures. Very large slaughterhouses specialize in butchering just one type of animal.
