[In some respects the laws] of kodashim are more stringent than [the laws] of temurah, and [in other respects the laws] of temurah are more stringent than [the laws] of kodashim: For kodashim can make a temurah, but a temurah cannot make a temurah. A community and partners can consecrate koda- shim, but they cannot make a temurah; and we can consecrate [as kodashim] fetuses and limbs, but we cannot make a temurah [with them].  [The laws of] temurah are more stringent [than the laws of kodashim]: For [temurah] sanctity takes effect on a permanently blemished animal, and [the animal] does not become deconsecrated with respect to being sheared and worked with. R’ Yose the son of R’ Yehudah says: [The Torah] treated an unintentional act like an intentional act with regard to temurah, but it did not treat an unintentional act like an intentional one with regard to kodashim.  R’ Elazar says: A mixed breed, a tereifah, [an animal] born through Caesarean section, a tumtum, and an androgyne do not become sanctified and they do not sanctify [other animals].

These are the kodashim whose offspring and temurah exchanges are similar to [the original kodashim] themselves: [Concerning] the offspring of a shelamim and the temurah of the [shelamim]; their offspring and the offspring of their offspring ad infinitum, these are all deemed shelamim. [Thus,] they require leaning, libations, and the waving of the breast and thigh. R’ Eliezer says: The offspring of a shelamim may not be offered as a shelamim; but the Sages say: It may be offered. R’ Shimon said: [R’ Eliezer and the Sages] did not disagree concerning the offspring of the offspring of a shelamim, or concerning the offspring of the offspring of a temurah, that it may not be offered. Concerning what did they disagree? Concerning the offspring [itself]. R’ Eliezer says: It may not be offered. Whereas the Sages say: It may be offered. R’ Yehoshua and R’ Papyas testified con- cerning the offspring of a shelamim that it is offered as a shelamim. R’ Papyas said: I testify that we had a cow that was a shelamim-sacrifice and we ate it on Pesach, and we ate its offspring as a shelamim on the festival.
