Evaluates genetic gain and economic benefits of female genotyping in Lacaune dairy sheep, suggesting profitability requires favorable conditions.

This research aims to assess the potential benefits of incorporating female genotypes into the Lacaune dairy sheep reference population.
Utilized a deterministic gene flow model to evaluate genetic gain and economic implications of female genotyping.
Analyzed scenarios of increased genomic reliability and varying genotyping costs over a 20-year period.
Compared costs and benefits of genomic predictions for production traits.
Detects a potential significant increase in genomic reliability (up to +0.20) at current genotyping costs.
Suggests a very low genotyping cost (€4/sample) is necessary to make female genotyping beneficial.
Finds that genotyping ewe lambs is not viable without additional benefits such as new trait predictions.
