Britt Berglund

Britt Berglund
Professor in applied animal genetics. My research is mainly on the use of genetic variation in traits important for a sustainable breeding programme.

Presentation

I am specialized in dairy cattle and do research and teaching in most important traits. One focus is the genetic background to reproduction- and health traits and new phenotypic measurements for the traits. I am quite heavily involved in teaching.

Teaching

I am course responsible for the animal science students in the Master course in Cattle production, and for the basic education of students in Veterinary Medicine where I am course responsible for the part course in animal genetics within the Population medicine course, and contact person for the Master Thesis degree project in veterinary medicine performed at our department.

Research

Prolific (Pluridisciplinary study for a RObust and sustainabLe Improvement of the Fertility In Cows)

An EU project (FP7-KBBE-2012, 311776) with participants from 13 organizations in 8 countries. The overall aim of PROLIFIC is to integrate the information at herd and at cow level to understand, predict and find solutions to improve dairy cow fertility for a robust cow of the future. I am/has been supervisor for two PhD students within this project:  Effects of diet on phenotypic responses and molecular mechanisms in reproductive tissues - Theodoros Ntallaris, and Genetics of fertility in cattle with whole genome genotypes imputed from sires sequence information. – Amabel Tenghe (PhD dissertation 170428).

Feed efficient cows

In the Nordic project Feed Utilization in Nordic Cattle (FUNC) our aim is to improve feed efficiency (FE) by breeding, feeding and management. A proper definition of FE will be developed together with correlated proxy traits measurable in large scale at reasonable costs. New tools to consider FE for a more efficient milk production with reduced environmental impact will be developed for use in a sustainable dairy production. The project has several part goals. The Swedish part is financed e.g. by SLF (V1230028). One of my PhD students studies Genomic and phenotypic indicators of feed efficiency. – Bingjie Li

Genetic and management aspects on oestrus expression in dairy cows

The aim of this SLF financed project (V0730301, V1130050) is to study which heat signs are the best to record heat expression ability in today's high producing cow and how these measures can be used as a management tool and as a breeding tool to genetically improve the heat expression ability and thereby the fertility of dairy cows. PhD student – Sofia Nyman.

Improved breeding for fertility in Nordic dairy cows by using new recordings and novel traits

The use of automated recording systems within the milk production is increasing. These have mainly been developed as management tools, but could potentially also be used as breeding tools. This project is part of the Nordic 4-year project Improving Nordic dairy cow fertility through genetics. The Swedish part is financed by SLF (O-15-20-587), and our focus area is to investigate how we best can use automated recordings to improve the genetic evaluation for fertility, such as return to normal cyclicity after calving, association to oestrus intensity and ability to remain pregnant.  Records are from activity tags, milk progesterone, milk composition, and the pregnancy protein PAG. Our hypothesis is that traits we can define from these new data have sufficient good quality to be used in the routine genetic evaluation which may increase herd profitability. A post-doc is working in this project together with the project leaders.

Genetic and genomic variation in fertility measures of dairy cows

In this project the genetic variation in new phenotypic measures based on endocrine levels in the dairy cow are studied, such as progesterone profiles post partum and their genetic relationship with the pregnancy result. The goal is to improve the genetic evaluation for fertility. PhD student – Sofia Nyman.
