All those who have learned Chulin, have probably thought about marketing Ben Pakuah. The Gemara says that if you Shecht the mother cow and find a live baby inside, the baby does not need Shechita. So why not produce a herd of such BP's? If they don't need Shechita, the price of beef could be brought down significantly for the kosher consumer.
See Chulin 74A
מתני' השוחט את הבהמה ומצא בה בן שמנה חי או מת או בן תשעה מת קורעו ומוציא את דמו מצא בן תשעה חי טעון שחיטה וחייב באותו ואת בנו דברי ר"מ וחכמים אומרים שחיטת אמו מטהרתוUPDATE:
As JS pointed out in the comments, once the animal "walks on the ground" it DOES require shechita midrabanan, so as not to have people think that animals do not need schechita. Yet the advantage is primarily in the hind-quarter, in that we don't need to take out the gid-hanasheh, enabling the HQ to enjoy kosher status. Also, the halachos of treifos and chailev are relaxed.
