Genetic merit of commercial lambs from year 1 to 20 after implementation of each scenario. Scenarios investigated: ‘base scenario’ represents the current Irish industry; ‘PRO-intense scenario’ incorporates a reduction in the proportion of rams that are selected for mating from the top 40% to the top 20% and no shift in market share; ‘PRO-market scenario’ gradually shifts the market share of the CON subpopulation to the PRO subpopulation; ‘PRO-intense-market scenario’ includes a combination of a shifting market share towards the PRO subpopulation and a reduction in the proportion of rams that are selected for mating from the top 40% to the top 20%; ‘PROFOR scenario’ shifts the market share of the CON subpopulation between PRO, FOR and PROFOR; ‘FOR’, ‘FOR-5’ and ‘FOR-10’ scenarios includes the commercial subpopulation sourcing FOR sires directly from New Zealand once, every 5 years or every 10 years, respectively
