Hullin

Hullin or Chullin (Hebrew: חֻלִּין, romanized: ḥullin, 'ordinary' or 'mundane') is the third tractate of the Mishnah in the Order of Kodashim and deals with the laws of ritual slaughter (שְׁחִיטָה, sheḥitah) of animals and birds for meat in ordinary or non-consecrated use (as opposed to sacred use), and with the Jewish dietary laws (כַּשְׁרוּת, Kashrut) in general, such as the laws governing the prohibition of mixed consumption of meat and dairy. While it is included in Kodashim, it mainly discusses non-consecrated things and things used as the ordinary human food, particularly meats; it is therefore sometimes called Sheḥitat Ḥullin (שְׁחִיטַת חֻלִּין, 'slaughter [of] ordinary [animals]'). It is composed of twelve chapters.. The rules prescribed for kosher (the adjectival expression of Kashrut) slaughtering include five things that must be avoided: There must be no delay during slaughter. No pressure may be exerted on the knife's moving backwards and forwards. The knife must not be allowed to slip beyond a certain area of throat. There must be no thrusting of the knife under the skin or between the gullet and windpipe. The gullet or windpipe must not be torn out of position in the course of slaughtering.
