The apparatus of the present invention serves to stun animals prior to slaughter, these being introduced with a gondola into a pit. On a sidewall of the pit is / are designed a gas module, preferably a plurality of gas modules. Each gas module comprises a gas introduction line having a multitude of pores through which an anaesthetic gas can flow laterally into the pit. The multitude of pores ensures a laminar inflow of the anaesthetic gas. The lateral laminar inflow of the anaesthetic gas avoids an increase in the stress of the animals being stunned, thus enabling humane stunning prior to slaughter. At the same time, the modular construction by means of the gas modules facilitates simple dimensioning of the gas introduction capacities required and also the construction and retrofitting of corresponding apparatuses.

A method for stunning and killing animals, suitable for poultry, pigs, chinchillas, mustelids, rabbits and fur-bearing animals is provided. The method involves introducing live animals to be slaughtered into a sealed chamber of a slaughter plant, adding to the sealed chamber at least one gas suitable for causing the animals to lose consciousness, performing a stunning stop so that the animals in the sealed chamber are at least partially stunned, creating a vacuum inside the sealed chamber until a predefined killing pressure is achieved, performing a killing stop so that the stunned animals in the sealed chamber are killed, opening the sealed chamber and extracting the killed animals. The gas insertion step may be preceded by a pre-suction step of air from the sealed chamber. The method minimizes damages caused by convulsive phenomena occurring in traditional slaughter methods.
