In December, CRV is introducing a new breeding value for its own bulls, which will enable a targeted and direct way to breed for feed efficiency. The index indicates how much more milk is produced by daughters of a particular bull using a kilogram of dry matter feed intake, compared with the population average. Good feed efficiency also means more efficient use of nitrogen and other minerals and a lower CO2 footprint for the production of milk.
The amount of milk a cow produces in kilos from a kilogram of dry matter feed intake. This defines feed efficiency in one s…read more ›
For years, the Netherlands has ranked among the best in class in terms of milk production per cow. Last year, a record for lifetime production was reached averaging 34,000 litres. Our recently published annual statistics reveal that higher production does not compromise the length of a cow’s life. The milk production of cows has increased in recent years while the animals have also reached a higher age.
For example, the annual statistics of Coöperatie CRV show that the longevity of Dutch herdbook cows increased by 2.5 months in the last financial year. Co…read more ›
De Rith Nora 265 smashed the barrier of 200,000 kg of milk today. The Addison daughter, who is owned by Adrion and Lisette van Beek from Breda, is the fourth cow in the Netherlands to achieve this amazing milestone.
Nora is much cleverer than her herd mates
Nora will be 19 years old this month. She has clocked up 12 milk yield records and took a total of 5457 days to reach the magic figure of 200,000 kg of milk. Nora was bred by Jos Peeters, Lisette van Beek’s father. She has spent her entire life at the De Rith dairy farm. Measuring just 143 cm in height, she is now…
CRV recently installed 40 roughage intake control feeders at Wietse Duursma’s dairy farm in Bellingwolde. These feeders measure the individual feed intake of the herd of 300 dairy cows. The measurements are vitally important in revealing the genetic variation in feed efficiency and further improving breeding values.
‘By working toward better feed efficiency, I can cut my feed costs by 2 cents per kilo of milk in the long term’, says Duursma. ‘As I supply three million kilos of milk every year, that converts to a financial gain of € 60,000.’ Duursma also mentions th…read more ›
A huge leap forward in the lifetime production achieved by cows at culling has been revealed in the 2018-2019 financial year. Compared with the previous financial year, lifetime production has increased by 1210 kg of milk and 96 kg of fat and protein. This is the first time that such a significant difference has been shown in two consecutive financial years. At culling, Dutch cows now note lifetime production that averages 31,553 kg of milk, with 1371 kg of fat and 1120 kg of protein. A combination of a longer productive life and higher milk production is behind this i…read more ›
