(PhD Thesis;2021:35, Doctoral thesis, 2021)Zambia is one of the largest aquaculture producers in sub-Saharan Africa, with tilapia production having increased exponentially during the last 20 years. Lake Kariba is the most active commercial fish farming site in the ... -
Studies of boar taint, with an emphasis on testicular function and development
(PhD Thesis;2015:43, Doctoral thesis, 2015)Boar taint is an odour reminiscent of sweat, urine or faeces, perceived as off-flavour when meat from entire male swine is heated. The compunds that cause boar taint are androstenone and skatole/indole. Androstenone is ... -
Studies of mechanisms of virulence of viral hemorrhagic septicemia (VHS) : comparison between different genotypes of the virus
(PhD Thesis;2015:17, Doctoral thesis, 2017-07-04)Viral hemorrhagic septicemia virus (VHSV) has four major genotypes (I, II, III, and IV) with different sub-lineages (Ia-e and IVa-c). VHSV infects a wide-host-range with a preference for low-temperature environments. The ... -

Studies on the interbranchial lymphoid tissue in the gills of Atlantic salmon and common carp
(PhD Thesis;2017:17, Doctoral thesis, 2017)As wild-capture fisheries exceed sustainable levels, aquaculture is expected to increase its importance as a source of fish products for a growing world population. Vaccination is a major prophylactic measure in modern ... -
Symmetrical onychomadesis and hypothyroidism in the Gordon Setter and English Setter
(PhD Thesis;2015:58, Doctoral thesis, 2017-07-04)Symmetrical onychomadesis (SO), also called symmetrical lupoid onychodystrophy, is a severe claw disease frequently seen in the Gordon Setter (GS) and English Setter (ES). Affected dogs will initially show sudden onset of ... -
The cellular prion protein and the inflammatory response
(PhD Thesis;2017:81, Doctoral thesis, 2017)The cellular prion protein (PrPC) is known for its pivotal role in the development of prion diseases, such as Creutzfeldt-Jakob disease in humans and scrapie in small ruminants. In these diseases, PrPC is converted into a ... -
The impact of management on dairy calf welfare
(PhD Thesis;2015:106, Doctoral thesis, 2016-05-19)No universal definition of animal welfare exists. However, an animal allowed expression of natural, innate behaviours, showing good biological functioning and having a positive affective state is generally viewed as having ... -
The interplay between IPNV and host cell machinery : possible strategies for immune evasion
(PhD Thesis;2016:46, Doctoral thesis, 2016)The aquatic birnaviruses cause diseases in different aquatic species worldwide. Infectious pancreatic necrosis (IPN), caused by IPN virus (IPNV) in salmonids, has arguably been the most economically important disease caused ... -
