however, im also an animal science major in a farming area, so our curriculums and learning strategies/examples are based on livestock. just so you know, im pre-vet.
with that said, this semester i am working with swine, and know about other livestock as well, but only know about big factories on the swine side. because of that, i skipped straight to the pig part of the video so i could possibly shed some light on that subject.
i do not agree with most practices of any part of these industries, but i do understand the reasoning behind what is done. also, the smithfield farms and packing plant is not like what is in the video.
we have university farms which we raise, sell, and teach with. we have about 70 sows/gilts and maybe less than 10 boars(we do artificial insemination). where to begin...the crates you see the pigs in are for the protection of the litter. pig will fight and could injure others and cause abortions. the next crates you see them in are also protection for the newly born pigs. they are designed so that the sow cannot lay down quickly. a mother laying on her litter is the number one cause of death. ear notches are for identification. tail docking is so pigs wont bite other tails, causing injury or infection. teeth clipping if also to prevent injuries. castration is because intact boar meat smells foul when being cooked. after weaning, the sows are moved into pens, 4 or less per pen and they have enough room. this is the end of the small farm.
ive been to smithfield farms. this is where i get into large, industrial factory farms. this was for a field trip in our swine class. pig health is the number one responsibility. they do not mistreat or beat them. they do kill pigs if they will not be suitable for market, but they do not keep them in pain or in a bad condition in hopes it will be able to produce something.
i didnt watch the slaughter part because i honestly never want to relive that experience. if you give me a few points that they said, i can give you what i saw.
again, i completely do not agree with the industry or most of what they do, but i have to suck it up until i get into graduate vet school, so i learn and understand what goes on.
