Even if it will be outdated we will not change but for now it is not outdated

Restraint devices are used for holding animals both for ritual slaughter and for conventional slaughter where animals are stunned. The use of a head restraint will improve the accuracy of captive bolt stunning. In large beef slaughter plants without head restraint captive bolt stunning has a failure rate of 3 to 5, i.e., a second shot is required.
Captive bolt and electric stunning will induce instantaneous insensibility when they are properly applied. However, improper application can result in significant stress. All stunning methods trigger a massive secretion of epinephrine (Van der Wal 1978; Warrington 1974). This outpouring of epinephrine is greater than the secretion which would be triggered by an environmental stressor or a restraint method. Since the animal is expected to be unconscious, it does not feel the stress. One can definitely conclude that improperly applied stunning methods would be much more stressful than kosher slaughter with the long straight razor sharp knife. Kilgour (1978), one of the pioneers in animal welfare research, came to a similar conclusion on stunning and slaughter .
Halal (Muslim) slaughter performed with a knife that is too short causes definite distress and struggling in cattle. We recommend to those Muslim religious authorities who require slaughter without stunning that they require that the knife must be razor sharp with a straight blade that is at least twice the width of the neck. Unless the animals are stunned, the use of curved skinning knives is not acceptable. Due to the fact that Muslim slaughtermen do not usually receive as extensive special training in slaughter techniques as Jewish Shochtim, preslaughter stunning is strongly recommended. As stated earlier, reversible head-only electrical stunning is accepted by most Muslim religious authorities. Preslaughter stunning allows plants to run at higher line speeds and maintain high standards of animal welfare.
Temple Grandin has stated that she has "observed that if the rules (of the five forbidden techniques) are disobeyed the animal will struggle. If these rules are obeyed the animal has little reaction.
Studies and experiments cited on orthodox Jewish website Chabbad.org include one conducted in 1994 by Dr. Temple Grandin - an Associate Professor ofAnimal Science at Colorado and a study completed in 1992 by Dr. Flemming Bager, Head of the Danish Veterinary Laboratory, which showed that when the animals were slaughtered in a comfortable position they appeared to give no resistance and none of the animals attempted to pull away their head. The studies concluded that the animals had no pain and were not even aware that their throats were cut.
Temple Grandin—a leading designer of animal handling systems—gives various research times for loss of consciousness via Kosher and Halal ritual slaughter and elaborates on what parts of the process she finds may or may not be cause for concern. Grandin observes that the way animals are handled and restrained prior to slaughter likely has a greater impact on their welfare than whether or not they are stunned. For this reason, "under the leadership of Grandin, research into animal welfare during slaughter has shifted away from examination of different techniques of stunning to a focus on auditing the performance actual slaughter plants operating under commercial conditions
