Description of research and teaching

I started my PhD project in June 2014 and I will defend my doctoral thesis in the beginning of 2019.  

In my PhD thesis, I'm studying the use of microalgae as a protein feed for dairy cows. The high protein content, rapid growth and high productivity of microalgae make them a very attractive alternative to conventional protein feeds. As they can be grown in land areas unsuitable for other agricultural production, microalgae do not compete with other food production for land area. These characteristics are valuable, as a future aim is to double food production for feeding the increasing human population while halving the ecological footprint.

The aim of my PhD project is to compare the effects of different microalgae species (Spirulina platensis, Chlorella vulgaris and Nannochloropsis gaditana) and conventional protein feeds (rapeseed meal, soybean meal and/or faba bean) on the feed intake, nutrient utilization and milk production of lactating dairy cows. In particular, the effects of different protein feeds on the nitrogen and phosphorus utilization of the animals are examined.

The data of my PhD project consist of four physiological trials each conducted with 4-8 dairy cows. Four peer-reviewed articles will be published of the trials. The supervisors of my PhD are docent Seija Jaakkola and professor Aila Vanhatalo (Department of Agricultural Sciences, University of Helsinki).
