Table 1 shows the average breeding values for health traits of the ten most used CRV sires compared with the ten most used imported sires and the ten most used Dutch sires from other suppliers. The evaluation looks at both young sires with a marker breeding value and daughter-tested sires. The figures show that daughters of the ten CRV sires will have healthier udders, be more fertile and be less susceptible to ketosis.
CRV sires win in terms of health and management
The most popular sires from the CRV selection clearly stand out from those of other suppliers when it comes to health and management traits. This emerges from an overview of the current breeding values of the most used sires in the financial year 2020-2021.
When it comes to management traits, the differences are even more pronounced. Calves of CRV sires are born more easily and will later calve more easily than the daughters of Dutch sires from other suppliers. In terms of behaviour, milking speed and lifespan, the ten most used CRV sires clearly stand out in a positive way.
