Further news has been released. The little calf was a COW, which makes this sad birthing event even more tragic. Of course given Tooth's overall genetic value, a calf of either gender would have been valuable to the population, but a little cow all the more so.
Regardless, as per the zoo, Sabie is in good shape after the birth, and it sounds like, although an unfavourable outcome, the birth went smoothly and without complications, so it should be a bright future for Sabie and her family all the same.

@Pongo , I beg to differ! Although Sabie does have five calves and two grand calves, yes, she herself is unrelated to Tusker and all his other progeny, and it’s also unlikely any of her sons with Tusker will enter the breeding population any time soon. A calf of either gender from her and Tooth would have been a valuable asset to the EEP, and while her matriline is safe purely in terms of living daughters/granddaughters, that’s no reason to put it on the back burner, so to speak, if an option such as Tooth is available! While Sabies lineage is safe, Tooth’s genetic legacy is in quite the opposite position at the moment, and will likely remain that way for some time, sadly.
