Increased yield per cow and an increasing number of dairy cows milked in automatic milking systems (AMS) constitute the current trends in Norwegian dairy production.
The current project focus on opportunities and challenges on Norwegian AMS farms such as; feeding, energy balance, health, and reproduction of cows milked by AMS, breeding for better adaptation of dairy cows to AMS, farmers technology adaptation and management of AMS farms. Furthermore, the applicability of milking time testing in AMS and milk quality are in focus. An important part of the project deals with the development of novel mathematical approaches to model multidimensional data.

Milk production, subclinical ketosis and reproductive performance of dairy cows are strongly influenced by their energy status during the first weeks after calving.
In the AMS herds, the cows meet new challenges in the environment and the breeding program needs to be adjusted accordingly with respect to traits, trait definitions and weights in the total merit index.
Technology adaptation and new management methods in AMS herds influence quality of life for farmers.
The main aim of the feeding part of the AMS-project is to develop procedures for dynamic adjustment of feeding in agreement with feed intake and energy balance
Evaluation of relationships between teat-end condition and milking time tests such as; milk flow, length of overmilking period, vacuum levels in the teatcups, total milking time and vacuum in the mouth piece chamber
Farms with high milk spore counts are selected for an in depth study on forage conservation, storage, and feeding management.
Univariate, multivariate and high-dimensional AMS and sensor data need to be combined in order to explain the complex biological processes which predict energy balance, subclinical ketosis, delayed onset of ovarian function, estrus and subclinical intramammary infections in cows
