Ask A Question on the daf
Previous daf Chulin 28
CHULIN 28-30 - Ari Kornfeld has generously sponsored the Dafyomi
publications for these Dafim for the benefit of Klal Yisrael.
1) DOES THE TORAH REQUIRE SLAUGHTER OF BIRDS? (cont.)
(a) Question (Mishnah): If Melikah was done with a knife (the
bird is Neveilah), one who eats the bird and his clothing
2) WHICH "SIMAN" IS SLAUGHTERED IN BIRDS?
1. Surely, since the spinal cord and neckbone were cut
before the Simanim, the bird is Treifah. However, if
the Torah does not require slaughter of birds, the
subsequent cutting of the Simanim is no worse than
Nechirah, the bird should not be Neveilah!
(b) Answer: Indeed, that Tana holds that mid'Oraisa, birds
require slaughter; Rav Yehudah holds like the following
1. (Beraisa - R. Elazar ha'Hakapar): "As you will eat
deer..." - what do we learn from deer and wild
(c) Question: Which Tana argues with R. Elazar ha'Hakapar?
2. Rather, the verse teaches that deer and wild goats
have the law of blemished Korbanos, i.e. they must
i. The Torah does not require slaughter of birds;
this is only mid'Rabanan.
(d) Answer: Rebbi argues with him.
1. (Beraisa - Rebbi): "You will slaughter like I
commanded you" - this teaches that Moshe received
laws of slaughter - that both the Kaneh (windpipe)
and Veshet (foodpipe) of animals must be
slaughtered, and in birds, one of them.
(a) (Mishnah): In birds, one Siman must be slaughtered.
(b) (Rav Nachman): Either Siman may be slaughtered.
(c) (Rav Ada bar Ahavah): The Veshet must be slaughtered.
1. The Mishnah says one Siman - it means, the special
one (that even a tiny hole in it makes the bird
(d) Question (Beraisa): If the Veshet was slaughtered, and
afterwards the Kaneh was uprooted - the slaughter is
1. If the Kaneh was uprooted before the Veshet was
slaughtered, it is invalid;
(e) Answer: It only taught the case of slaughtering the
Veshet, for it is common for the Kaneh to become
uprooted, not for the Veshet to become uprooted.
2. A case occurred in which the Veshet was slaughtered,
and the Kaneh was found to be uprooted; it was not
known if it was uprooted before or after the
slaughter - the ruling was, this is invalid, like
all doubtful cases of slaughter.
3. (Culmination of question): The Mishnah omits the
case of cutting the Kaneh, and finding the Veshet
uprooted - this suggests, it does not suffice to cut
(f) Question (Beraisa): If half of each Siman of a bird was
slaughtered, the slaughter is invalid - all the more so,
regarding an animal;
1. R. Yehudah says, the Veshet and veins of a bird must
(g) Answer: R. Yehudah only mentioned the Veshet because it
is near the veins (but one could just as well slaughter
the Kaneh and veins).
(h) Question (Beraisa): If one slaughtered half the Kaneh,
paused the amount of time needed for slaughter, and
completed the slaughter, it is valid.
1. Suggestion: This discusses a bird; he finished
cutting the Kaneh.
(i) Answer: No, it discusses an animal; he completed the
entire slaughter (the Veshet and the other half of the
(j) Question (Beraisa): If half the Kaneh was already cut
before slaughtering, and he cut a drop more and completed
the slaughter, it is valid.
1. Suggestion: This discusses a bird; cutting a drop
more of the Kaneh completes the slaughter.
(k) Answer: No - it discusses an animal; 'he completed the
slaughter' refers to cutting the Veshet.
(l) Question (Beraisa): Melikah of a Chatas - he cuts the
spinal cord and neckbone without cutting the majority of
surrounding flesh, until he reaches the Veshet or Kaneh;
he then cuts one Siman, and the majority of surrounding
flesh with it.
1. In an Olah, he cuts both Simanim or the majority of
(m) Question: What was the conclusion of the argument between
Rav Nachman and Rav Ada bar Ahavah?
i. Rav Ada bar Ahavah is refuted.
1. Question: We just said that Rav Ada was refuted!
(n) Answer: We derive the final ruling from the case of a
goose that was found in Rava's house; its neck was full
2. Answer: That was only regarding Melikah, since the
spinal cord and neckbone are also cut (it suffices
to cut either Siman with them - regarding slaughter,
perhaps the Veshet must be cut!)
1. Rava: How can we try to permit the goose?
3) CUTTING THE VEINS
i. Suggestion: If we will slaughter it and then
check (if the Simanim were already cut) -
perhaps the knife will cut where there was
already a hole, and we will not know that there
was a hole there before the slaughter!
2. Rav Yosef, son of Rava: We can check the Kaneh,
slaughter the Kaneh, and then turn the Veshet inside
out to check it!
ii. Suggestion: We will check the Simanim and then
iii. Rejection: Rabah taught, one cannot check the
Veshet from the outside (for it is red, perhaps
there is a tiny hole that was filled with a
drop of blood and is not noticeable), only by
turning it inside out.
i. This shows that either Siman is valid for
(a) (Mishnah): R. Yehudah says, he must (also slaughter the
4) CUTTING HALF A "SIMAN"
(b) (Rav Chisda): R. Yehudah only said this regarding birds,
for it is normal to roast them whole; animals are
normally dissected into pieces, the veins need not be
1. He holds that R. Yehudah requires cutting the veins
in order that the blood will exude at the time of
(c) Question (Mishnah): R. Yehudah says, he must *slaughter*
the veins (it should suffice to puncture them)!
(d) Answer: Indeed, R. Yehudah means, he must puncture them!
1. He said 'slaughter' to show that they must be
punctured at the time of slaughter.
(e) Question (Beraisa - R. Yehudah) The veins are part of the
(f) Answer: R. Yehudah means, they must be punctured at the
time of slaughter.
(g) Question (Beraisa - Chachamim (to R. Yehudah): Since the
veins must be cut solely to remove the blood, what
difference does it make whether they are slaughtered or
1. Inference: R. Yehudah holds that they must be
(h) Answer: Chachamim asked, what difference does it make
whether they are punctured at the time of slaughter or
1. R. Yehudah holds, the blood only exudes if they are
cut at the time of slaughter, for it is warm then.
(i) Question (R. Yirmeyah): According to R. Yehudah, if one
paused during the cutting of the veins or cut them by
Drasah, what is the law?
(j) Answer (An elder citing R. Elazar or R. Yochanan): They
may be punctured with a thorn (i.e. the laws of slaughter
do not apply).
(k) Support (for Rav Chisda - Beraisa): If half of each Siman
of a bird was cut, the slaughter is invalid; obviously,
the same applies to animals;
1. R. Yehudah says, in a bird he must cut the Veshet
and the veins.
(a) (Mishnah): Cutting half a Siman of a bird (is invalid).
(b) (Rav): Exactly half is considered like a majority. (We
are thinking that he said this regarding slaughter.)
(c) (Rav Kahana): It is not like a majority.
1. Rav understands, the tradition about slaughter says
that the majority cannot be left uncut.
(d) Question #1 (Mishnah): Half of one Siman by a bird, one
and a half Simanim by an animal - the slaughter is
2. Rav Kahana understands, the tradition says that the
majority must be cut.
1. According to Rav, this is like cutting the majority,
the slaughter should be valid!
(e) Answer #1: Mid'Oraisa, the slaughter is valid; the
Mishnah teaches a stringency mid'Rabanan, lest a person
will slaughter less than half.
(f) Question #2 (Rav Katina - Mishnah): (If an oven broke and
one of the pieces comprises the majority, it is Tamei.)
If an oven was divided into two equal parts, they are
Tamei, for it is impossible to make them exactly equal
(we cannot discern which is the majority, so we are
1. Inference: If they could be made exactly equal, they
would be Tahor.
(g) Answer #1 (Rav Papa): A shard is Tamei only if it is the
majority, it cannot be that each of the two halves is the
majority. (Rav only said that the Torah does not require
slaughtering more than half, there is nothing
contradictory about this.)
2. According to Rav, each should be considered like the
majority, both should be Tamei!
