The average lifetime production realised by cows in The Netherlands has increased by almost 2500 kg of milk and 200 kg of fat and protein to 34,000 kg of milk.
The lifetime production of Dutch dairy cows has never been so high as seen in the 2019-2020 financial year.
This has been revealed by the annual milk recording statistics released by CRV cooperative. A combination of a longer productive life (+75 days) and higher milk production (+0.2 kg of milk per day) is behind this increase in lifetime production.
Rolling annual average increases
In this financial year, the rolling annual average of Dutch dairy cows also increased to 9203 kg of milk with 4.40% fat and 3.60% protein. The percentage of protein and kilograms of milk is still showing a rising trend.
The herd size on the farms participating in milk recording has increased this year from an average of 99 cows to 104 cows. As the cows are kept on the farms for longer, the number of culled cows was at a relatively low level. The number of productive days increased by 75 days to 1183. This means that the average number of calvings has risen to 3.6 calvings per cow. The calving interval has remained stable at 407 days.
Almost all breeds showed increased production this year.
The milk production of black-and-white Holsteins rose further from 10,522 to 10,688 kg of milk, with 4.34% fat and 3.56% protein in 358 days of production. Red-and-white Holsteins produced fewer kilos of milk on average than black-and-white, but with clear higher components. The milk production of this group of cows rose to 9,838 kg of milk with 4.54% fat and 3.67% protein
The 2018-19 NZ Dairy Statistics demonstrated that New Zealand’s cows are also producing more than ever before. The latest report will be available later in the year.
