Genetic Parameters for Parasite Traits
Following work by the PRLB group, genetic parameters for parasite traits have been re-estimated. Details here.
Lleyn Connectedness Run – January 2019
This Excel sheet shows the connectedness (genetic linkage) between individual flocks within the breed analysis. Whilst colour categories show the degree of linkage between flocks as being adequate (green), limited (amber) and low (red) the most important aspect of this report is the relative ranking of flocks to each other – something that can be deduced from looking at this table.

Lleyn Reports 2018
Please note that publication criteria are still to be implemented in reports for new traits. When completed, trait EBVs will not show for individuals who have accuracy values below the thresholds shown below:
FEC (Combined) – 50% / FEC S – 50% / FEC N – 50% / Saliva IgA – 50% / Lamb Survival – 50% / Lambing Interval – 30% / Age at First Lambing – 40% / Longevity – 25%
The New Lleyn Index
The new Lleyn index is now live for 2017 breeding evaluations. The change follows close discussions with breeders and several changes to the EBVs generated for Lleyn evaluations.
The new index focuses on optimising, rather than maximising traits by continuing to improve maternal ability, lamb growth rate and muscling but also rewarding sheep with ‘optimum prolificacy’, controlling ewe mature size and penalising the leanest breeding lines in addition to the fattest.
The new index will be shown on reports instead of the previous maternal and carcase+ index. Individual EBVs will still be visible so breeders can continue to use these how they wish.
We expect changes in animal rankings, it is important not to compare the new index value with previous indexes.
