Worldwide breeding index 2019: Focus on fat, new traits and additional indexes
Several years have passed since the last calculation of the worldwide breeding index (2013), which Holstein International did regularly since 1996. Enough time, which national breeding associations and other organizations used to develop new statistical models based on changing economic realities and the discovery of new relevant breeding traits. The results can be seen in the worldwide breeding index 2019, in which the ratio for fat to protein is a lot closer and which includes various new traits. And more changes will be coming in the next few years, as a lot of research is going on for traits like feed efficiency.
