Or here's another piece with material borrowed from the above:
"and another piece:
"There's a huge difference between horses, sheep, and deer. Deer and sheep are both domesticated and farmed for commercial use of their particular yield (mean, dairy products etc). There's also the hunting process which I'm absolutely against due to the fact it is not only inhumane but unnecessary.
The way horses are slaughter is absolutely barbaric. Horses aren't restrained when they use a captive bolt gun to their heads. It often takes multiple hits to fell them and horses struggle violently in the box to regain their footing. The captive bolt was initially designed to fell cattle, which are restrained. A cow's brain is much for forward sitting in the skull and that's why the captive bolt is an effective method for them. A horse's brain sits much further back under the ears practically and is much harder to reach unless the technique used is correct (shooting at a downward angle along the neck) most horses stand much taller then slaughter plant processors and as such they use a cruel method of hitting the animal multiple times, including in the neck, shoulder, and back, to get them to go down in the box so they can reach their heads better.
They then only render the animal unconscious, not dead, and string them up to cut their throats and bleed them out. They die because of exsanguination. Not because they're shot in the head.
Keep in mind even heavily pregnant mares are slaughtered and animals sick with infections and disease. That is all transfered, unclean, onto your plate.
The next point, and biggest point against slaughtering horses for human consumption is the fact that horses are treated with a broad spectrum of drugs and medications that are DEADLY to people with consumed. 98% of race horses and 95% of performance/recreational use horses alone are treated with a human toxic anti-inflammatory and pain management drug known as "bute" aka Phenylbutazone. They're also treated with wormers, or anti-parasitic agents, that are also harmful to humans such as ivermectin, panacur, pyrantel, etc etc. If NOT treated, or not treated properly, for worms a horse's worm count can exceed 1:100,000. Meaning for every one worm or internal parasite a human host carries, a horse carries 100,000. Those parasites can leave the intestinal tract and wreak havoc on our bodies. Watch "Monsters Inside Me" on Animal Planet for a more complete view on what can happen.
So really it has nothing to do with "ZOMG DON'T KILL THE PRETTY PONIES! UR SO MEAN!" but has everything to do with "If you eat them, you're going to die much sooner then if you didn't from a host of illnesses from poisoning to cancer". All in all the humans consuming the processed horses are being subjected to cancer causing toxins that can destroy our hearts, digestive, reproductive, and circulatory systems if ingested AND subjected to parasites that can wreak havoc in our digestive tract while moving to other parts of our body via our blood stream. No joke. It's an exact science.
Why the Canadian and Mexican slaughter houses now fall under a direct law that went into effect earlier this month that prohibits the slaughter of horses with unknown medical histories for a minimum of six months and that all horses that are injured/ill must still be medicated and horses must still be properly wormed/drenched with anti-parasitic agents. It's a lose/lose for the slaughter industry as a whole simply because there are no known medications that treat the ills of horses that are approved for use in animals intended for human consumption. By 2013 a new law will be in effect stating that animals intended for slaughter must have their full medical history presented from birth to time of slaughter in one fully documented record.
Why? Because there are NO DRUGS on the market that treat the ills of horses that are approved for use in animals intended for slaughter.
So... Unsafe meat + Inhumane slaughter practices = Ban against horses for the purpose of human consumption and thus the major difference between lamb and venison."
You guys make the call :)
