Reply To: What have you "given up" to be frum?

“you may slaughter of your cattle and of your sheep, …and you may eat in your cities, according to every desire of your soul”

And a shochet makes a blessing before slaughtering an animal.

“Also, could kohanim during the time of the Beis Hamikdash keep a slaughter-free diet?”

I could imagine that an individual kohein might be able to pass on the meat, and only eat the minchah offerings, but SOME kohanim had to eat the chatat and asham offerings. To offer a korban with the intent that it not be eaten within the prescribed time is a very serious sin.

“I am not aware of any commandment that requires me to have chicken, lamb, veal or any other slaughtered meats. Just curius, perhaps you can instruct me otherwise.”

I am also not aware of any that are in effect in our times. At least for chickens and veal there are serious questions as to whether the typical treatment of those birds and animals is in accordance with halachah and in the case of veal, there are sources that indicate that the veal might actually become prohibited for consumption or even for benefit. CYLOR.
