CRV is introducing a unique breeding value for feed efficiency on December 1st 2020. CRV is the only company in the world to base this breeding value on real feed intake data. We currently collect feed intake data from over 1,800 lactating cows on a daily basis. In combination with data collected from over 7,000 Dutch and Flemish cows, this yields the most reliable breeding value in the sector.
Efficient and sustainable herds
Efficient and sustainable cows generate immediate benefits for both dairy farmers and society. Feed costs represent about 60% of all variable costs involved in milk production. Breeding for feed efficiency saves on average 10% on feed costs. In addition, efficient utilisation of feed also has a positive impact on the environment as it reduces greenhouse gas emissions and the use of scarce resources.
CRV, leading in feed efficiency
In 2017, CRV became the first herd improvement org+anisation to start large-scale measurement of the feed intake of dairy cows on five working farms. The aim is to reduce the feed costs for milk production. We currently collect feed intake data from over 1,800 lactating cows on a daily basis. This gives CRV a leading position in the collection of real feed intake data.
Greater profitability through higher revenues
Using the breeding value feed efficiency soon results in 10% higher milk production for the same feed costs.
Feed efficiency: the amount of milk produced by a cow per kg of feed
An average cow in CRV’s test programme produces 1.46 kg FPCM per kg of feed. There is a wide variation between cows (1.1 – 1.9) and herds (1.2 – 1.6). The 25% highest scoring cows for feed efficiency in the herd produce 0.4 to 0.5 kg of milk more with the same amount of feed than the 25% lowest scoring cows for feed efficiency. Using more efficient cows also reduces manure and methane emissions.
Highly reliable breeding value
In our actual bull portfolio the reliability of the feed efficiency breeding value with CRV daughter proven bulls is 85 – 90%. That is the result of analysing the measurements on the farms in the programme. From December 1st, farmers can select bulls based on this new breeding value.
