[Jacob-list] lamb color

[Gooch]

It's entirely possible that there may have been a non-Jacob ram at the old farm- I'll have to contact them to find out.  The ram that the ewes were exposed to here is a full 4H Jacob.  http://www.flickr.com/photos/asylumfarm/412099581/

I do have other breeds here, but they are in different pastures.  But- as always- anything is possible.  Someone could have jumped a fence...and then gone back to their own pasture or done the deed through the fence.

They'll be nice fiber animals if their fleeces are acceptable.  My girls like them any way!  We'll see what the rest of the ewes have.

The "white cap" coloration is generally considered an indication of cross breeding on one side or the other.  The lamb has the Jacob dominant black gene, but not the spotting gene.  It's quite possible for a sheep to look like a Jacob and not produce true to type.  This is where good records and progeny testing become even more important so that you have the information to begin to isolate the "guilty" party.   Shel, you mentioned that you are not really sure if your ram is the sire.  Were there other breeds at the farm?  If you really want to be sure, you can do a dna paternity test on the lambs.  Do you have other lambs by this ram?  Other lambs by this ewe?  Check out the breed standards at: http://www.jsba.org and http://www.jacobsheepconservancy.org and see if either the ewe or the ram are "iffy" in any other area.

 

JSBA and JSC both have open flock books, which means that if a sheep meets the standard it can be registered in JSBA or certified in JSC.  JSC also requires progeny testing for animals from unregistered parents to pass registration, but you'll find that JSBA breeders are also doing their own progeny testing.  You have a pretty flock and one odd birthing is just another puzzle.
