I actually watched the movie now. They make conditions much worse then they are know days. In might take place in foreign countries, but not in America.
Granted i live on a small family farm so it isn't that bad here. We have chickens that we raise and butcher ourselves. There are some that die from heart attacks, but you can't help that (we don't give them anything to make them grow faster). We have laying hens also, but they have plenty of room. The only way they get lame is by roosters fighting.
We also have pigs. Yes they kept in crates like you see in the video, but only for 2 or 3 weeks. In the video they don't show people giving the baby pigs shots so they stay healty and cutting off their teeth is good thing. I do disagree with slamming them on the floor.
A classmate at school works at a pig place like that. He said that the only time they use the bolt gun is to kill the sow(mother pig) when it is giving birth and it can't get it's pigs. So they shoot it and perform a seesection on the sow to save the baby pigs. I thought this was cruel at first, but if they wouldn't do it the sow and the pigs would die so at least they save the baby pigs. He also said that they use carbon dioxide to kill sick pigs.
It is the same thing with cattle. We give them shots and pour liquid over them to keep the lice away every year. It is good for them even though it hurts them. Just like you don't want to get a shot, but it will be good for you in the long run.
My Grandpa owned a dairy and the holsteins (black and white cows) were never hurt by the machines. It just sucks the milk out, it can't hurt them. The conditions were never bad for them.
When they say the animals die on the trailer to market. That happens sometimes, but the owners want to avoid it as much as possible or else they won't get their money for the animal.
All i'm saying around here conditions aren't that bad.
Sorry for any grammar mistakes i don't want to proofread it.
Don't feel to sorry for animals. They get to eat and sleep and s*** all day long, a man's paradise.
