The effect of arginine on root system development in Norway spruce (Picea abies L. Karst) somatic embryos
The demands for higher production yields and better quality materials from the forests are increasing globally. Tree breeding programs are directed to meet the future demands on forests. In order to capture the full benefits from the breeding programs, clonal propagation is necessary. For most conifer species, somatic embryogenesis (SE) is the only available option for large scale clonal propagation of Elite clonal material. For Norway spruce (Picea abies L.
The use of artificial insemination in dairy farms in urban/peri-urban Kampala, Uganda : a study of knowledge, attitude and practices
Uganda is one country with fastest growing populations in the world and with more than 25% of the population living in poverty. There is a rapid rural urban migration with increasing demands for food for low income earners especially in these areas. One way to mitigate food insecurity is to increase milk and meat production efficiency, and thus reproductive performance of cows is crucial for good production. A well-documented strategy for improving dairy cow productivity through faster genetic improvement is to breed dairy cows using proven semen via artificial insemination (AI). AI has been used in Uganda for over 60 years but only less than 10 %, a small population of the country?s herd has been bred that way.
The aims were to study knowledge, attitude and practices factors influencing cow fertility results on dairy farms around Kampala using AI and to propose ways of promoting increased use of AI in Uganda.
Flotation therapy for downer cows : a retrospective study of cases treated with flotation therapy at the Large animal clinic at the Faculté de Médecine Vétérinaire at Université de Montréal
There are about 700 000 dogs in Sweden. Roughly 70 % of the dogs are purebred and registered in the database at the Swedish Kennel Club (SKC). The database includes records of birth date, pedigree, offspring and results from e.g. veterinary examinations related to genetic health programs.Every year approximately 10% of the dogs die; most are euthanized by a veterinarian. Dog mortality data is stored as digital medical records at animal clinics and in insurance databases.Dog owners tend to register their puppy in the SKC, but they rarely report that the dog has passed away.
Näthinnesjukdomar hos hund :
An array of different retinal disorders is present as a threat in quite a
number of dog breeds. These often lead to profound visual impairment or
blindness. Many of the disorders are genetic, and they are, in Sweden as
well as in other countries, subject to breeding programmes.
The anatomy of the eye and the retina, as well as current examination
techniques (ophthalmoscopy, electroretinography (ERG) and genetic
analysis) are described. The more common retinal disorders encountered
in dogs in Sweden are discussed: retinal dysplasia, generalized
progressive retinal dystrophy, retinal pigment epithelial dystrophy, collie
eye anomaly, sudden acquired retinal degeneration, retinal detachment
and choroiditis. The possibly affected breeds are listed.
The value of diagnostic findings is discussed and current advances on the
subject in ophthalmologic research are accounted for..
A comparison of group housing and individual housing for dairy bulls kept for breeding
This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.
Prevalence of congenital defects in Swedish Hampshire, Landrace and Yorkshire pig breeds and opinions on their prevalence in Swedish commercial herds
This study concerns congenital defects in pigs; umbilical and scrotal hernia, cryptorchidism, kyphosis, splay legs, anal atresia, intersexuality and congenital tremor. The aim was to describe and estimate the prevalence of these defects and estimate the heritability for the most frequent defects, scrotal hernia and cryptorchidism in purebred Swedish Hampshire, Landrace and Yorkshire populations. Furthermore, information and opinions from herdsmen in commercial herds was collected and analysed. A low proportion of congenital defect pigs is of importance both from animal welfare and economic point of view. The accuracy of registration of the presence of defects in the litters has a decisive role for the ability to select against these defects.
Hur kan man få ned dödligheten hos kalvarna i dikobesättningarna?
This work is a literature review along with interviews from nine suckler herds. How to reducecalf mortality in the cow herd is the focus of this paper. To get profitability of a herd, it isimportant that you get a live calf per cow and year. Good fertility of the cows thus is veryimportant. During the years 2007 - 2008, approximately 5.5% of all calves born by beef cowsdied and about 8.5% of the calves born by heifers died.
Rengöring, desinfektion och förvaring avendoskop i djursjukvården
With a starting point in the legislation for organic production set up by the Swedishcertification organization KRAV, the reasons to why these regulations are important isexplained and how pigs are affected by these rules. The study also shows how well the pigscope in the organic environment considering the origin of the genetic material; from theconventional pig population. The conclusion is that pigs do function fairly well in the organicproduction environment and the traits affecting their functionality involve: motheringabilities, strong legs, good meat quality, good sow durability and longevity, capacity to eatmuch roughage and dark skin color. There are however still many ways of improving theorganic population of pigs to make them more adjusted to the organic environment; forexample different traits brought into the breeding goals and the choice of good parent animals..
Vegetationshistoria de senaste 5000 åren kring Fållnäs gård, Södermanland : med tyngdpunkt på antropogena aktiviteter
The manor Fållnäs gård is situated at the northern end of the bay Fållnäsviken, c. 12 km north-west of Nynäshamn, Sweden. A 300 cm long sediment core collected in the bay has been analyzed regarding pollen stratigraphy. AMS 14C dating of terrestrial macrofossils indicates that the sequence covers the last c. 5400 years.The aim has been to study vegetational changes, especially human impact, in the surroundings of Fållnäs gård.

Hjortpark, kronoskog och ladugård : En bebyggelseundersökning av Skyttsie Hage på Skanörs ljung
This essay is about a deserted medieval habitation called Skyttsie Hage which is located in the south of Sweden in the Scania province where it lies on a moor on the Falsterbopeninsula. Remains of five to six larger buildings have been found here with a surrounding earthwork, although it's not known for sure what kind of habitation they have been part of. Local folklore from the 17:th century states the area as a place where pirates lived, and that this was the reason for it's devastation. Another says that there once stood a breedingfarm belonging to the danish crown. Archaeologists have made several speculations which includes a deer park, a royal estate, an isolated farm or a smaller village.

Erhållen feedback användes i förbättringsarbetet av måltiderna.
Effekter av predationsrisk på sånglärkors (Alauda arvensis) habitatval på åkermark
Along with other European farmland birds, the skylark (Alauda arvensis) has declined rapidly since the 1970?s. Between 1975 and 2003, the Swedish population of skylarks declined with 64 %. In Britain, the decline is often explained by alterations in farming practices in general and the shift from spring-sown to winter-sown cereals in particular. The dense vegetation structure of winter cereals is limiting the number of breeding attempts possible, causing the entire population to decline.
Cystocentes versus spontankastad urin : tillförlitlighet vid klinisk diagnostik hos tik
This master thesis was conducted in order to investigate the effects of the browsing
species Yeheb on animal tissues in Swedish landrace goats and to make a literature
review in order to increase the knowledge of the importance of this plant for livestock
production in Somalia. The evergreen Yeheb bush is a very important feeding source for
grazing and browsing animals in Somalia during the dry period. Yeheb contains
cordeauxiaquinone that stains the bones of the animals red/pink, which has been an
increasing problem when exporting meat to foreign countries. In an experiment, two
goats were fed dry and fresh leaves from the Yeheb bush for one and two months,
respectively. The goats did not feed the intended amount of dry leaves, since the supply
and palatability was not as high as estimated.
