How to interpret (81:4) without hadith? She-camels??

[Lobotomize94]

Quran 81:4 by Sahih international says: And when full-term she-camels are neglected

I looked up the root of that word, "she-camels above in the corpus" and here is what I got: http://corpus.quran.com/qurandictionary.jsp?q=E$r#(81:4:2) . I see a lot of "ten" and "relatives", but only one instance of She-camel.

Could the she-camel is a concept of Islamic Secondary sources that was placed into the translation of the Quran?

Another English translatio] changed 81:4 completely and said this:
"81:4. When the relationships are suspended." This is completely different from the she-camel thing?

This book here claims to just translate without having any bias for any school of thought! Which translation is correct?

I'm only concerned because I use the second book as my quran and I hope it is not a poorly translated version

I'm in the same boat. Im using seven interpretations and I can safely say all are influenced by secondary sources OR traditional types.  The safest I would say is corpus word by word literal and and the rest to God the Almighty's mercy and guidance.
Context is highly important too.
For now however, good deeds, charity and prayer seem to work the best.
