Sire nominations open

Sire nominations are now open for the 2025 Resource Flock joining.

Approximately 120 sires selected from the nomination process are artificially inseminated to ewes across two sites. The progeny from these matings are genotyped and measured throughout their life and are taken through to slaughter, where a range of post-slaughter measurements are taken.

Please complete the form below to nominate your rams.

Selection criteria of sires for the resource flock

The MLA Resource Flock aims to develop an industry reference population and focuses on diversity more than genetic merit.

Key selection criteria include:

• Relatedness to animals already in the MLA Resource Flock – animals that are less related to the animals already used in the resource flock are preferred.
• The age of animal – is the animal reflective of the industry into the future? Younger animals are more likely to be related to future populations.
• Representation of the breed in the industry.

Annually approximately 120 sires are selected from a range of breeds. The number of sires selected from each breed depends on the:

• representation of these breeds in industry
• size of the reference already created for each breed.
