Nordic Total Merit Index

A powerful tool for dairy farmers

What is NTM?

We are always talking about NTM, Nordic Total Merit index. But what is NTM? What does it mean? What makes NTM one of the most progressive breeding value systems in the world? 

NTM is a combined index of different genetic traits that are heritable through mating bulls with cows. The purpose, of course, is to develop the cattle’s ‘genetic capital’ to achieve higher profitability and functionality of the herd by breeding new generations of cows with higher capability e.g. for milk production and resistance to diseases.

90 different sub-indices are combined into 15 main traits. That makes NTM the most complete total merit index in the world. A balanced breeding between production and health is what you get.

NTM weights

NTM is about money

With NTM you are always breeding for better productivity, better health and good functional conformation. Our breeding goal is to improve the health of cattle in each generation while increasing production as well. Healthy cows have a long lifespan (i.e. longevity) and cost less, therefore improving the profitability of the herd. The weights vary a bit between breeds.
