1. Genetic and clinical studies of teat traits in the pig
Abstract : A major goal of pig breeding is to produce sows with good longevity, which can raise many uniform litters with healthy, fast-growing piglets. The fitness of the sow, including the presence of sufficient number of functional teats, is one key to the success of the initial rearing period of the piglets. READ MORE

2. Genetic Heteroscedasticity for Domestic Animal Traits
Abstract : Animal traits differ not only in mean, but also in variation around the mean. For instance, one sire’s daughter group may be very homogeneous, while another sire’s daughters are much more heterogeneous in performance. The difference in residual variance can partially be explained by genetic differences. READ MORE

3. Bovine milk microbiota - methods matter
Abstract : The idea of a bacterial community, a microbiota, in milk with the purpose of inoculating the offspring's intestine for a better start in life is very appealing from an evolutionary perspective. The overall purpose of this thesis was to investigate if such bacterial community exists in bovine milk from healthy individuals and to describe factors that affect the microbiota. READ MORE

4. Genetic variation of in-line recorded milkability traits and associations with udder conformation and health in Swedish dairy cattle
Abstract : Slow-milking cows lead to less efficient use of automatic milking systems (AMS) or may hold up the milking process when many cows are milked together in conventional milking parlours (CMP). Traditionally, genetic evaluations for milkability have been based on subjective observations, where the herdsmen have scored the animals once on a scale from slow to fast milking. READ MORE

5. Milk removal : effect on milk yield, milk composition and milking efficiency in dairy cows
Abstract : Milk from dairy cows is a staple dietary component for humans all over the world. Regardless of whether milk is consumed in its purest, unaltered form or as high-end products such as fine cheese or ice cream, it needs to be of high quality when taken from the cow, produced at a low price and produced in a system that consider aspects such as animal health, animal welfare and sustainability.
