Longevity

CRV’s pathway to a healthy and efficient herd
  • Breeding for higher longevity
  • Extra revenues
  • More savings on replacement costs

Longevity

Older cows have higher production and a lower environmental impact. The first productive years of a cow are necessary to payback the cost involved in breeding her, and it is only in later lactations that a cow actually starts earning.

Older cows produce more milk, which means that average production is higher. They also reduce the need for replacement in the herd, which implies that fewer young cattle have to be raised. The culling of cows is ‘voluntary’ (insufficient production), or ‘involuntary’ (other traits such as fertility, health). In practice, culling is usually motivated by multiple reasons. Healthy and productive cows form the foundation of a long life.

“Big Boukje 192 (s. Cash) produced a whopping 208,000 litres of milk with 4.64% fat and 3.86% protein making her the first cow in the Netherlands to smash the barrier of 200,000 litres”
Jos Knoef, dairy farmer Geesteren, the Netherlands

CRV, leading in longevity

CRV has a long tradition of focussing on high lifetime production and longevity. Thanks to the high volume of data collected by Dutch and Flemish farmers, and the use of unique predictors, the breeding value for longevity is one of the most accurate and reliable breeding values in the world.

Longevity explained

Longevity proven in practice

A study among more than 22,000 animals also examined the performance of culled cows. The results revealed remarkable differences between the 25% highest scoring and the 25% lowest scoring cows for CRV Efficiency.

The highest scoring cows were not only more productive, they also had longevity of 274 days more. This resulted in a difference in lifetime production of more than 13,000 kilos of milk and more than 1,000 kilos of fat and protein. The best cows also had a significantly higher genetic level for longevity and CRV Efficiency. Breeding for Longevity really does pay off in practice!

CRV longevity facts

  • Over the past 60 years, a total of 37,777 cows have achieved 100,000kg of milk production in the Netherlands
  • More than six CRV cows* per day reach the exceptional milestone of 100,000kg of milk production per day
  • At culling, Dutch herdbook cows* note a lifetime production that averages 31,553kg of milk, with 1,371kg of fat and 1,120kg of protein (2019)
  • The Dutch cow Big Boukje (Cash x Labelle x F16 x Tops) was the first cow in the Netherlands to smash the magical 200,000kg milk barrier
  • Longevity is part of the CRV Efficiency index, a unique index that helps to breed highly productive cows that convert feed efficiently into milk and achieve high lifetime production
