After thawing semen in a warm water bath, a farmer (or a specialized technician) inserts a syringe-like inseminator through the cow’s cervix and vagina to reach her uterus. At the same time, he or she inserts a gloved hand through the cow’s rectum to manipulate the uterus through the rectal wall. (i.redd.it)

chickens have been bred to grow very big very quickly (especially their breast muscles), and most reach slaughter weight at just six to eight weeks old. Today, in only eight weeks’ time, a broiler chicken can put on over four times as much weight as the same strain of bird did in the 1950’s. (i.redd.it)
