No idea on the FG's or their crosses.
I absolutely love the Rex coat. Rex usually have a very good loin too.
I've had pretty solid results in a first generation cross of a black NZ/Altex doe and a chocolate Rex buck. They grew like weeds , those that were butchered dressed out very well.
I kept one doe blue from the first litter , she's now just over a year old and bred back to her sire produced 8 in her first litter ~18 days ago.
I had a pure Rex litter from the same buck and a very nice doe who are one day older but are quite a bit behind these NZ/Altex/Rex crosses in size while they also they seem to be much more mature , actively out of the nest while the pure Rex aren't doing much roaming around.
Originally the idea behind this cross was to improve the shoulders of my Rex herd and add black to the palette , both of which appear to have been delivered as they are little meat bricks with broad shoulders and I did get one black with Rex fur that I will likely be keeping.
I wasn't expecting to get the size and growth rate improvements I've seen in the first two generations but am thrilled with the results.
The first generation doe is a little over 13lbs which is pretty shocking considering her sire is a bit over 8 and her dam about 9 and 3/4. It appears thus far that she has passed some of the size / growth rate traits of the NZ & Altex on to her offspring considering they're outpacing the older litter from a fantastic mother.
My only concern at this point is stray guard hairs in this second generation and beyond but I'll have to wait to see how their coats are as they mature.
