The sentence you wrote is almost correct! Here is the original sentence:
"Lambs eat grass and salt to grow big horns, just like the adult argali sheep."
Here are some helpful points:
- Lambs: Lambs are baby sheep.
- Horns: Usually lambs (baby sheep) don’t have big horns yet.
- Correction: The sentence is grammatically okay but the idea is a bit tricky. Young lambs don’t usually eat salt to grow big horns. Adult argali sheep have big horns, but lambs usually don’t, so it might be clearer to say that argali sheep eat grass and salt to grow big horns.
If you want to keep your sentence and make it clearer, you could say:
"Argali sheep eat grass and salt to grow big horns, just like the adult ones."
or if you want to talk about lambs specifically, say:
"Lambs eat grass and salt as they grow, but only adult argali sheep have big horns."
In short, your grammar is fine, but the meaning can be clearer!
