The ProCROSS Ranking (PCR) is formulated to help those using this structured breeding programme – which alternates the VikingRed, VikingHolstein, and Coopex Montbéliarde breeds – to improve the profitability of their herds through better genetic selection.
The formula of the PCR is built with two key considerations that differentiate it from pure breed indexes. One is its recognition of the relative differences between the breeds, allowing the crossbreeding producer to gain more of each breed’s strengths.
The other accounts for hybrid vigour, also known as heterosis, which is the uplift in performance that comes through breeding unrelated bloodlines. Heterosis greatly improves health and fertility traits, as well as lifespan.
