Top 10% farmers in the Netherlands are above 5 lactations per cow
A common challenge for dairy farmers across the world is to increase longevity of their dairy herd. The average number of lactations across the world is about 3 lactations per animal (see Figure 1). This average is fairly constant between countries with a high milk production compared to countries with a low milk production. It is known however that the number of lactations per cow varies enormously within countries. The average number of lactations in the Netherlands for example is 3.5 lactations per cow, but the best 10% of Dutch farmers are above 5 lactations per cow.
