Slaughterhouse technology: Stunning with good Animal Welfare


Anyone that thinks modern agriculture is some non-technical or backward technology is showing their profound ignorance.

Captive Bolt Pistol: is a device used for stunning animals prior to slaughter. Proper stunning is essential to prevent the pain and suffering of the animal during the bleeding (exsanguination) process (which is itself necessary to prevent meat spoilage) during butchering. The principle behind captive bolt stunning is a forceful strike on the forehead using a bolt to induce unconsciousness. The bolt may or may not destroy part of the brain.

The bolt itself is a heavy rod made of non-rusting alloys, such as stainless steel. It is held in position inside the barrel of the stunner by means of rubber washers. The bolt is usually not visible in a stunner in good condition. The bolt is actuated by a trigger pull and is propelled forward by compressed air or by the discharge of a blank round ignited by a firing pin. After striking a shallow but forceful blow on (or through) the forehead of the animal, spring tension causes the bolt to recoil back into the barrel. Wikipedia

    Ah! The Captive Penetrating Bolt Gun Cattle Stunner!

    Can this be compared to the “Propaganda Machine” controlled by those who benefit from franchising that stuns prospective franchisees into a stupid state where they are easily tricked into signing self-defeating non-negotiable and long-term contracts —because they are investing in good faith and they think the franchisor is selling in good faith.

    How can we, Les, overcome a Propaganda Machine where under ADVANTAGES of Franchising there are 17,300,000 entries in a Google Search and where in DISADVANTAGES of franchising there are only 77,000 entries — and most of the 77,000 entries don’t talk about the real disadvantage of franchising, the elephant in the room?

    Have a great weekend, Les
