It's the reason why naked mole rats don't have nociceptors and can't feel pain: they live in an environment where their blood is always relatively high in CO2, so, if they did have nociceptors, they would fire constantly. That's also high-school biology.

Besides, I think some farmed animals, such as sheep and cows, have another major artery on the back of their neck, so cutting the front and the side of their neck really doesn't stop the blood from getting to their brain.
Wait, you are talking about the jugular vein? Well, that certainly doesn't cause fast death.
