How do I use the Genetic Merit, Trait Criteria table? (show/hide answer)

First select the type of sheep you are looking for – Dual Purpose to breed replacement ewes or Terminal Sire to produce only lambs for carcass production.

Now choose what traits you want to base your overall index of merit on by ticking the boxes in the “Use” column of the Goal traits section of the table. Note that you can still show SIL sub-indexes for traits that are not in your overall index of merit by checking the “Show” box for a trait while leaving the “Use” box clear.

Choose minimum or maximum constraints for only a few indexes (or BVs). Putting too many constraints on will lead to few or no animals found.

To view BVs to place constraints on, tick the box in the top right corner of the Criteria table.

Alter the sort criteria as required.

Select age of animals you want to find. Note that if you have a very wide range the search may fail due to too many animals being found or taking too long to find animals that match your other specifications

Select region if you want – SIL recommends you do not initially

Pick progeny birth years if you want to restrict a search to animals with progeny

Specify Genetic Vision or Breed proportions to restrict the search to the genotype of animals you are looking for. Another note tells you more about what Genetic Vision is.

Use the flock criteria to restrict a search to just three or less flocks and/or exclude just three or less flocks from your search

Hit the search button at the bottom of this window to start your search.

What does Genotype Specification mean? (show/hide answer)

NB: The breed names used in eSearch are based on information provided to SIL for flocks and for individual animals. While effort has been made to ensure accuracy, in some cases these may not be correct.

Genetic Vision is like "breed" but it accounts for the fact that some flocks are marketed based on a breeding strategy or brand and may have more than one breed in the background pedigree.
You cannot select multiple breeds for this variable. You must conduct separate searches for each breed you may be interested in.

Breeds in Pedigree allows you to specify which of several breeds may (or may not) be in the pedigree background of animals you are searching for.

What are the current index and breeding value definitions? (show/hide answer)

You can view the current definitions (PDF, Adobe Reader or equivalent required).

Why is there a grey arrow linking the eBVs Lamb Growth and Adult Size? (show/hide answer)

Selection for faster growth is expected to lead to increases in adult size if genetic merit for adult size is ignored. SIL recommends that both Lamb Growth and Adult Size be included for DP sheep indexes where rams are used to breed replacement ewes. However, you can choose whether or not to do this because there may be circumstances where genetic merit for adult size is not wanted in the index for total genetic merit. The grey arrow linking these Goal Traits for DP sheep is a reminder that these two traits are closely linked genetically.

Search times out before giving you results? (show/hide answer)

If you have very few restrictions the eSearch engine will find so many animals that the search stops. Try adding some more criteria to focus your search more. Timeouts often occur if you select ANY for genetic vision and you apply no index or eBV trait thresholds.
