Explain your idea

An automated structure for farming passive mobs for drops while also enabling "filtering" of baby animals to prevent complete annihilation of your "crop" of animals.

Features:

1. Conveyor Belt Input with filter option for certain animals or babies
2. Redstone Control to toggle
3. Item Output for animal drops; possible fluid output for MRM (Mechanically Reclaimed Meat). MRM fluid Could be made into extra food.
4. Suggested power cost: 128 rf/t

That sounds cool. But could there be a way to form the mystery meat into patties that have either a forge:steak, forge:chicken etc. tag so that it can work in recipes like farmers delight?
