I warmly welcome other Mod authors to expand and create based on this Livestock Cow Mod, enriching the world of Factorio together. This Mod aims to provide a basic livestock framework, such as core mechanisms for cow breeding, feeding, and product generation, and provides clear APIs and data structures to facilitate interaction and modification by other Mods. For example, other Mods can:

• Add new cow breeds: Introduce special cow breeds with different products and needs, such as dairy cows with higher milk production, beef cattle with higher meat production, or mutant cows that can produce special materials.
• Expand the feed system: Add new crops, feed processing methods, or introduce more complex feed formulas to make livestock farming more challenging and interesting.
• Integrate with other Mods: Integrate cow products with the production lines of other Mods, such as using milk to make special potions or using leather to craft more advanced equipment.
• Add new buildings and equipment: Design buildings and equipment specifically for cow breeding, product collection, and processing, such as automatic feeders, milking machines, slaughterhouses, etc.

I believe that through the joint efforts of the community, more interesting and innovative content can be created, making Factorio's livestock industry more colorful. I encourage Mod authors to actively share their work and exchange ideas and suggestions with me.
