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 ›
The income over feed costs is a key financial factor for Willem Alders. Feed intake data really opened his eyes to the individual differences between cows. ‘The poorest performing animals add little or nothing to the total income over feed costs. However, the best performing animals contribute more to the profit than expected’, he states.
Willem Alders had expected there would be differences, but such a large variation in feed conversion rates between individual cows came as a big surprise to the dairy farmer. The Alders family from Overloon started registering the …read more ›
Two years ago, CRV became the first cattle improvement organisation in the world to start large-scale measurement of the feed intake of dairy cows on working farms. CRV is convinced that targeted breeding still has huge potential to improve the feed efficiency performance of cows.
In 2020 CRV will collect the feed intake data of more than 1600 cows. This data will be used to work towards ultimately reducing the cost price of milk production and increasing the sustainability of dairy farming.
