Maybe stupid question but 1.5kg empty or full?

We all know 1.5kg femail minimal breeding weight. But after 160gr medium rat defecation she can be say 1350... So whats the verdict? To breed or not to breed thats the question...
Is 1.5kg all times or sometime?

It's just a guide line. But it's empty. Breeding is more than 1500 g it's is the female ready?

1500 on empty but there is more than just weight, there is also age, and even then an animal of proper weight and age might still not be a good candidate, it's about proportion too.

Yeah like the above.

Personally i go through my females like this:

Age > how does she look > how is she feeding > what is her weight

I am sorry. Of course age is 2+ years

And proportions are good and 8mm follicles

I figured that the 1.5kg weight and 3 years old meant 1.5kg after pooping and not yet eaten on top of the age. Then again I'm only planning to breed mine after I get them well past the 1.5kg weight.
