hello! my question relates to the issue raised by rav yirmiyah regarding the shechita of a ben pekua.
rav mesharshiya claims that according to shitas chanaya we should say that when considering the case of a ben pekua that mates with an ordinary animal the resulting offspring is ineligible for shechita. my query relates to the possible aspect of "braira". the gemara in many places seeks to resolve whether we say braira or not. it would seem to me that our case here would test braira strongly. namely if braira works we should have a solution to the case just described: say that the shechita is huvrar to be the part that is not the ben pkua and is kosher or that it is huvrar that the siman was that of the ben pekua and the result of the shechita is similarly not in doubt
thanks for your always excellent research and thought

Here, the problem is that the offspring of the Ben Paku'a does not possess two Simanim, the Kaneh (windpipe) and Veshet (esophagus), as Rashi (DH Ein) writes. Since the father does not require Shechitah, it follows that one Siman of the child is considered as having been slaughtered already.
Rashi gives two possible ways of understanding how the animal is lacking two simanim: (a) half of the Simanim have already been slaughtered; i.e., half of every molecule of the Kaneh and half of every molecule of the "Veshet"; (b) either the entire Kaneh or the entire Veshet has been slaughtered and the animal remains with just one complete Siman.
According to either approach, the offspring animal is certainly left without two Simanim, and this does not depend on Bereirah. Since the Mishnah earlier (27a) states that one must slaughter the majority of two Simanim of an animal, it follows that this child cannot be slaughtered because it inherited only one Siman from its parents.
