This achieves rapid initial blood loss and the shortest time to loss of brain function. Sticking should always be carried out with a sharp knife at least 12cm long. Next: Cattle and Calves. Back to top.
Gas killing The majority of poultry chickens, hens and turkeys in the UK s are now killed using gas. There are a number of different types of gas killing systems and gas mixtures that may be used. Birds remain in their transport crates and are placed into a gas system where they are exposed to mixtures of air and gas, until dead.
This method avoids the need to handle and 'shackle' live birds, so has some welfare advantages. UK law states that animals must be killed, not just stunned, using this method. Slaughter without pre-stunning religious slaughter Please see our religious slaughter page.
Print Slaughter Factfile. Did you find this useful? These opinions identify indicators of consciousness or sensibility in animals at slaughter.
Examples of indicators are breathing or blinking, but indicators vary depending on the animal species and the stage of the slaughtering process.
Experts also give indications on how to calculate the number of animals to be checked during monitoring. EU legislation on the killing of animals aims to minimise the pain and suffering of animals through the use of properly applied stunning methods, based on scientific knowledge and practical experience. It applies to farmed animals. English en Select your language.

It was obtained by subtracting the weight after bleeding WAB from the weight before slaughter WBS live weight and multiplying it by Anil et al.
Following carcass splitting, the lungs of the animals slaughtered by Kosher method went through the conventional bedika procedure Gregory et al, The bedika procedure involves the examination of the internal organs to ensure that the animal's health meets the Talmudic standards of wellness at the time of slaughter. However, lung examination stands as the focal point of bedika. It seeks to identify evidence of pleural adhesions that might, for example, indicate a punctured lung.
The lungs are filled with air and submerged in water as a test of pulmonary integrity. After this procedure, the lungs and tracheas were removed to subjectively score the amount of blood in the trachea BLT and blood splash BS in the lungs.
This was done in accordance with the works of Gregory et al. The BLT was scored by cutting out about 25 cm of the trachea and opening it along its length up to the upper bronchi with a sharp knife to observe and quantify the amount of blood. Bright-red blood-tinged foam was also observed in some of the tracheas from the Kosher-slaughtered animals.
The amount of splash could easily be seen as dark patches as they were scattered over the two lobes of lungs. Some were split open with a knife to observe the extent of the splash and to ascertain the freshness of the blood.
In total, sets of lungs and tracheas were observed and scored for Kosher while were scored for conventional slaughter. The conventional slaughter was done by stunning with a pneumatic captive bolt gun which uses compressed air Anil et al.
The animals were restrained in a v-shaped metal box with an open top and with a rear gate to prevent the animals from struggling or moving backwards after entering the box. They were restrained in an upright position and the shot was delivered to the forehead. They were then released from the box, hoisted and cut to bleed on the bleeding rail almost immediately. Every other procedure after this was similar to the Kosher except that the lungs did not go through the bedika procedure.
The tracheas and lungs were also scored as for Kosher. Percentage blood loss was also obtained as for Kosher. Statistical analyses was performed using SAS Analyses of variance were done using the general linear model GLM procedure to analyse the percentage blood loss.
Percentage blood in the trachea and percentage blood splash was analysed using the Proc Logistic procedure and using type 3 analyses of variance and Chi square to determine the P values. Proc Frequency procedure was used to determine the frequencies and percentages. Results and Discussion. This accords with Anil et al. Additionally, they also recorded more blood loss in the captive bolt stunned group conventional group compared to the non-stun groups.
Anil et al. They also found no difference in the packed cell volumes between the two slaughter methods. In the present study, the mean percentage blood loss for the Shechita group was 2. Thirty-two percent of the tracheas examined for Kosher slaughter also had bright-red, blood-tinged foam while none of the tracheas examined for conventional slaughter had blood-tinged foam. Concerning blood splash, the same carcasses and numbers used for the analyses of blood loss and presence of blood in the trachea were used to subjectively quantify the percentage of blood splash in the lungs.
There have been reports of more efficient exsanguinations after Shechita compared to using captive bolt, pre-cut Miller, ; Levinger, ; It was claimed that blood loss can be impeded by stunning as a result of neurological, muscular and cardiovascular changes caused by stunning.
The authors further claimed that the deep respiratory movement and gasping after Shechita makes exsanguination better and that because contraction occurs towards the end of the bleeding, the remaining blood is forced out of the vessels. In the past, concerns were raised about blood aspiration in cattle slaughtered in the inverted position for ritual slaughter when the cut was made Blokhuis et al.
This study shows that animals slaughtered in the upright position without pre-stunning exhibited similar behaviour. This result is also similar to Tsokos et al. Blood was found in the respiratory tracts due to aspiration.
Gregory et al. The presence of the blood-tinged foam indicates that blood has been expelled from the lungs following churning in the alveoli through breathing actions before reaching the exsanguinated state.
