Position – Professor of the Polish Academy of Sciences

Field of interest-  genetics, animal breeding, organic cattle breeding, milk and beef properties

Scientific achievements ca. 139 publications, 64 papers from JCR list. Author and co-author of 11 books and monographs. Total citations ca. 244. Hirsch index – 9.

Selected scientific achievements:

1.Development of the cattle slaughter performance assessment method on live animal and chilled carcass based on computer image analysis of the animal's body shape and assessment of the carcass muscularity and fatness, according to the EUROP system, and MLD cross section.

2.Co-author of the implementation guide for improving the dietary value of milk produced on low-cost and ecological farms by modifying the composition of pasture and meadows sward.

3. The vitamins A, β-carotene, E, K2 and D3 and TAS content in milk has been doubled during the winter feeding period after supplementation of the cows' diet with the addition of flaxseed oil. These values were significantly brought to their levels from the pasture feeding period. In milk of the supplemented cows was also observed significantly changes in the quantity and quality of milk fatty globules, which have a positive effect on the improvement of the milk technological usefulness  for cheese production.

Realized research projects – Performer of two grants within the frame of European Research Area (ERA) and one within the frame of Horizon 2020:

1. Grant within the frame of CORE Organic Plus: “Towards preventive health management in native dual-purpose cattle adapted to organic pasture based production systems via novel breeding strategies based on novel trait recording”. Grant is being realized in 2015-2018  

2. Grant within the frame of ERA NET Susan: “Increasing productivity, resource efficiency and product quality to increase the economic competitiveness of forage and grazing based cattle production systems”. Grant will be realized in 2017-2021

3. Grant within the frame of the call H2020-SFS-2016-2017 (Sustainable Food Security – Resilient and resource-efficient value chains):”Genomic management Tools to Optimise Resilience and Efficiency” (GenTORE) which will be realized in 2017-2020.
