Dear Matthew
Genomic selection is being used for selection by some dairy goat and dairy
sheep breeders in New Zealand, Australia, soon Norway and also United
Kingdom. This is in addition to what Dominique has summarised for Europe.
To expand: dairy goat breeders involved with us at AgResearch have been
using genotyping by sequencing aka restriction enzyme reduced
representational sequencing (GBS) and around 56,000 SNPs are used by the
method. In the flocks involved, all the relevant animals are genotyped and
the method is the GRM being used for GBLUP/ssBLUP, also provides DNA
assigned parentage (for sales), and information for mate allocation to
minimise inbreeding. Currently, ~40,000 animals will have been genotyped by
this method since 2016. The base breeds involved in NZ and Australia
primarily consist of Saanen but have some Swiss Alpine and a little
Toggenburg. Genomic selection using this genotyping method is currently
under development in Norway by NSG.
SRUC and Yorkshire Dairy Goats (YDG) are doing genomic selection and have
done so for a number of years using the IGGC 50K goat SNP chip in a
composite of Saanen, SwissAlpine and Toggenburg I understand.
As far as dairy sheep are concerned, genomic selection using 15-18K ovine
SNP chips in East Friesian, Lacaune, and Awassi crosses and composites is
being undertaken in several large flocks in New Zealand.
Hope this helps
Cheers
John

Dear Matthew,
Genomic selection is been used in France to select dairy sheep (Lacaune and
Manech breeds) and goat (Alpine and Saanen breeds). Last week at PAG
Virginie Clment (from IDELE) described the genomic selection approach for
French dairy goats. I believe there are also some genomic selection schemes
in place in Spain (Laxta dairy sheep) and Italy (Sarda dairy sheep). But as
I'm not an expert someone else could probably give you more information on
those breeds.
Best regards,
Dominique

Objet: dairy goat/sheep genomics
Does any country have genomic breeding values for dairy goats or dairy sheep?
I know some have genetic BV, but have any implemented genomic BV and if so
for which breeds?
FYI-ABS is not getting into the dairy sheep/goat business this is me
helping get an answer for a non AnGenMap/non academic scientist
Thank you, Matt
