Entering lamb deaths for Sheep Genetics
Entering lamb deaths for Sheep Genetics
When an animal has a lamb and it dies at birth, how does it get recorded as a dead lamb for the purpose of Sheep Genetics analysis
In order for Sheep Genetics to deliver accurate genetic information,
ALL
lamb deaths should be recorded for the dams who have been confirmed as pregnant but do not drop a live lamb. (i.e. do not carry the lamb to term or birth a dead lamb at term)
The full parentage of a 'phantom' (or dead) lamb should be recorded, substituting DAB (dead at birth) in the ID.
For Example: 509999-2015-DAB001, 50999-2015-DAB002 etc.
Note:
It is important that the phantom lamb information includes the sire and dam, otherwise the reproductive information cannot be used to feed back into breeding values
