Kil'ayim (Talmud)

Kil'ayim (Hebrew: כלאים, lit. Mixture or Confusion) is the fourth tractate of Seder Zeraim ("Order of Seeds") of the Mishnah and of the Talmud. There is both a Mishnah Kil'ayim (m. Kil.) and a Tractate Kil'ayim (t. Kil.). Kil'ayim deals with the laws of various forbidden production and uses of mixtures, as provided in Leviticus 19:19 and Deuteronomy 22:9-11. Specifically, it discusses planting mixtures of seeds, grafting, mixtures of vineyards, crossbreeding animals, working with a team of different kinds of animals, and shaatnez (clothes containing a mixture of linen and wool). There is a Gemara from the Jerusalem Talmud.
