To be honest Horse slaughter is neccisary. There are to many unwanted messed up horses out there...either they will be given to crap homes and be abused or starved or they can be sent to slaughter.
Right now slaughter is a mess because the horses are shipped to mexico...they need to re-open the US plants for the horses sake...
As for drugs...dont get me lying..I don't know a thing.
Personally I could never eat horse meat. I don't know why I just couldnt...guess cause I would be thinking of the fact that I own 2 and could be eating their brother or something...idk im weird...but I don't have a single issue with people eating horses, or any other animal for that matter...and I can eat other animals. I eat cow chicken etc...and trust me..I live out in the boonies. I know where food comes from and how its processed. I guess my main issue is that horses have face value to me...cows and chickens have always been food to me. Now if I owned chickens...they would be for eggs only, I couldnt eat them because they would be more pets to me. And if I ever owned a cow it would have to be a milk cow cause I would never be able to eat a cow I raised. Im just to darn emotional lol...to many pets to love...perhaps I could do like my granny did.
She didnt want to eat her own cows cause they were her pets...so she sold them to the guy down the road and in exchange he would butcher one of his cows and give my granny the meat. Thus she didnt eat her own cows lol.
I just couldnt eat an animal I had raised...all my animals are pets...and ill prob bury my horses when they die cause im sentimental.
As for quality of meat...Ive heard that yearlings make the most tender meat and are a favorite meat source in japan...past that the meat begins to taste better as it ages until it hits a peak...but yea...yearlings are suppose to be the most tender, not neccisarily the most flavorful...but this is not personal experience...just random stuff I have read.
Horses Will Listen...Even When No One Else Could Possibly Understand...
