Question: What is Isas ha'Kelavim?

Answer #1 (Reish Lakish): It is anything in which bran is mixed in.

Support (Mishnah): 'When shepherds eat from it' - sometimes shepherds do not eat from it (due to the bran).

Answer #2 (R. Yochanan): It is anything made like buns.

Support (Beraisa): If he made it like buns, it is obligated [in Chalah]. If he made it like boards, it is exempt. (We explained this like GRA.).

(R. Ba citing Shmuel, and R. Ami citing R. Chiyah Ruba): Even if he made it like nice buns [it is exempt].

Question (Mishnah): If shepherds do not eat from it... (if it is like nice buns, surely shepherds eat from it)!

Answer: The case is, initially he made [the dough with intent] that shepherds will not eat from it. (It is exempt even if he reconsidered and made it like nice buns.)

(Mishnah): One may make it on Yom Tov [when shepherds eat from it, even though part will be for dogs - R. SHLOMO SIRILIYO].

Our Mishnah is like R. Shimon ben Elazar;

(Beraisa): One may not make [food on Yom Tov] for Motza'ei Yom Tov, but a woman may fill a pot with meat [and cook it on Yom Tov], even though he will eat only one piece. One may fill a kettle with [and make] hot water, even though he will drink only one cup. However, to bake, she bakes only what she needs;

R. Shimon ben Elazar says, a woman may fill the oven with bread, because bread bakes nicely when the oven is full. (We explained this like GRA.)

(Beraisa): Stolen Matzah, one may not bless on it.

Source (R. Hoshayah): This is due to "u'Votze'a Berech Ni'etz Hash-m."

Limitation: This refers to l'Chatchilah, but not at the end. He owes [only] money to [the owner, so he was Yotzei b'Di'eved].

Note: Even if he stole baked Matzah, he acquires it through Shinuy (chewing it), so it is already his before he swallows it.

R. Yonah says that an Aveirah is not a Mitzvah. R. Yosah says that a Mitzvah is not an Aveirah.

(R. Heila): "Elu ha'Mitzvos" - if you do them like the Mitzvos should be, they are Mitzvos. If not, they are not Mitzvos. (Perhaps R. Yonah, R. Yosah and R. Heila argue with R. Hoshayah, and say that even b'Di'eved he was not Yotzei. We explained this like ROSH, Pesachim 2:18.)
