(B) The method of induced faint faint caused many species to the selection of simple, safe, not only meet the health requirements, and ensure the principle of quality meat. Commonly used methods are the following: 1. Electric Power Law Ma Ma method is a widely used method of causing faint. When electric current caused by anesthesia animal carcasses brain experimental status epilepticus, slaughter livestock pounding heart, it can get a good bloodletting effect. Pig artificial electric Ma's voltage is generally 70 ~ 90V, current of 0.5 ~ 1.0A, electric stunning time of 1 ~ 3s, brine concentration of 5%. Ma automatic electric voltage does not exceed 90V, the current should not exceed 1.5A, power hemp time 1 ~ 2s. 2. Carbon dioxide anesthesia method This method is to slaughter animals through containing 65% ~ 75% CO2 (generated by dry ice) in a closed chamber or tunnel through 15s. CO2 anesthesia so that the pig in a quiet state, unknowingly into a coma, so the less muscle glycogen depletion, animal carcasses can completely unconscious, anesthesia was maintained to achieve the purpose of 2 ~ 3min.
(C) the assassination of bloodletting after the faint great ham hanging from the pulley to hang suspended by the trolley tracks, transported to the bloodletting at the assassination of bloodletting.

It can not be scratched when peeling leather, with less fat fat. In the process of stripping the entire operation should prevent dirt, fur, dirty hands and clothes stained carcass.
(V) 1. The Ripper and eviscerated carving knife piercing the anus peripheral ring, carved circles, dig open the large intestine head vertically into the pelvis. 2. Pick the chest, abdominal 3. pull the rectum, bladder cut 4. Take the intestines, stomach (belly) 5. Take heart, liver, lungs 6. Rinse pleural and peritoneal
(Vi) to the head, feet, split half
(Vii) carcass renovation, refurbishment of reinspection is to remove the carcass of a variety of surface dirt, repair diseased tissue cut off the carcass on the damaged tissue and tissue was free, removal impede meat hygiene tissues and organs, and the carcass irregularities section to make the necessary repair cut plastic, so having a carcass intact product image.
