Did you know that NTM is one of the world’s most progressive breeding value systems?
The Nordic Total Merit Index (NTM) is a combined index of different genetic traits heritable by mating bulls with cows. It aims to develop cattle’s “genetic capital” to increase herd profitability and functionality. This is achieved by breeding new generations of cows capable, for example, producing more kilos of milk fat and protein and having better disease resistance.
NTM comprises more than 90 sub-traits combined into 15 main ones.
Different combined indices weight traits differently depending on the breeding goal. Some emphasise cows’ conformation (Frame, Udder, Feet and Legs), others focus on production (i.e., how much milk the cow produces), and some target health traits (e.g., resistance to hoof and udder diseases).
