Dietary fibre composition and sensory analysis of heat treated wheat and rye bran
When grains of wheat and rye are conventionally milled, large quantities of bran classified as by-products are left and are mainly used for animal feed. Bran is a complex material composed of the aleurone layer, nucellar epidermis, a seed coat, a fruit coat and a small proportion of the germ and endosperm depending on extraction rate. The bran fraction consists of approximately 40-50 % dietary fibre which can contribute to increase the nutritional quality of human cereal food. It would also be valuable for the food industry to convert by-products as bran to products with higher commercial values.
The aim of this thesis was to analyse the content and composition of dietary fibre of heat treated wheat and rye bran according to the Uppsala method with some modifications in order to analyse soluble and insoluble dietary fibre separately. Half of the bran samples were precooked, dried and roasted and the other half dried and roasted (uncooked).
Orsaker till mekaniska skador på nötslaktkroppar som uppstått under transporten till slakteriet eller på slakteriets stall :
In the Swedish abattoirs there are assistants that judge the slaughtered animals in regard to diseases and injuries. All diseases and injuries assign different codes. This master?s thesis is about code 42 which means injuries of different kinds like for example bruises etc. These injuries have risen during the transport from the farm to the abattoir lairage or during the stay at the lairage before slaughter.
Bacterial contamination of eggshells in deep litter floor systemsand conventional cages in Jordan
This study was carried out in Jordan with the purpose to investigate the bacterial microflora of egg shells from cage systems and from deep litter floor systems. Another aim wasto get a general impression of the hygiene, at farm level, of egg production in Jordan andthe factors affecting it.Eggs from two cage systems and three floor systems were analyzed, regarding bacterialcontamination of the egg shells. Egg samples were taken from the storage room, the eggcradle in the cage system and from the nest and floor in the floor system. To get a generalimpression of the hygiene at the farms, swab tests and air tests were performed. Swab testswere performed with a sterile cotton swab at the same units as the eggs were sampled andair tests were performed by opening petri dishes where the hens were staying.
Kognitionsforskning i djurhållningen: grisars kognition och dess tillämpning vid slaktsvinshållning
Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made.
A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.
Inhysning av struts :
The Swedish ostrich production started about thirteen years ago and still there are no Swedish recommendations regarding ostriches? space requirements. The European Council give recommendations and the Swedish Board of Agriculture (SJV) has a proposal, but so far the producers follow Danish regulations regarding space requirements. The Swedish Animal Welfare Agency are about to set standards for the ostriches? space requirements, and therefore the Swedish ostrich producers, together with The Federation of Swedish Farmers (LRF) ask for a scientific background to these decisions.
This thesis is a preliminary study at the prospect of a future experiment on which factors important for ostriches? space requirements and welfare will be examined more thouroughly.
Närklimat vid avvänjning av smågrisar :
SUMMARY
Several studies have shown that weaning pigs are in great need of heat. The reason for this is
mainly because the pigs are given very little feed just after weaning. Some of the pig producers
of today have tried to get along with these problems by building some kind of hut for the
pigs. Some of these pig houses have been included in this study.The study has shown shortcoming
functions for the pig cottage. The expected heat increase has not occurred.
Hemlösa katter i Göteborg med omnejd
Today there are over 100 000 stray cats in Sweden and of these 10 000 are found in Gothenburg. There are several instances that try to reduce the number of stray cats. The problem for stray cats is primarily the suffering they may face in hunger, cold, predators, diseases, parasites, accidents, etc. The cats receive no veterinary care and may die from a simple infection that easily can be cured with antibiotics. Stray cats also can spread diseases to domestic cats, be a sanitary problem and compete with other small predators on prey.
Authorities working with stray cats are the Country Administrative Board and the police authority.
Åkerböna till slaktkyckling - effekt av enzymtillsats
I Sverige är soja det vanligaste proteinfodermedlet inom fjäderfäproduktionen. Att utfodra med inhemska proteinfodermedel istället för soja kan göra slaktkycklingsproduktionen mer hållbar. I Sverige är åkerbönan ett alternativ att ersätta sojan med då den är rik på råprotein och skördarna i landet har ökat de senaste åren. Åkerbönan innehåller dock antinutritionella substanser (ANS) så som tanniner, trypsininhibitorer och lektiner, som försämrar näringsupptaget hos kycklingen. Vitblommig åkerböna innehåller låg mängd av tanniner, men innehåller däremot trypsininhibitorer och lektiner, vilket kan medföra att det blir svårare för kycklingen att tillgodogöra sig protein, vilket kan leda till försämrade produktionsegenskaper.
Wolf movement patterns and the distribution of moose kills : implications for human harvest?
Most studies regarding wolf (Canis lupus) predation on moose (Alces alces) have focused on the total annual consumption of moose within a wolf territory but few have tried to describe the spatial impact of wolf predation on a local scale. In this study I have analyzed wolf movement data, wolf predation, moose hunting statistics and moose hunter observations to investigate how wolf predation affects the human harvest of moose in Scandinavia. Since wolves prey on mostly juvenile moose during summer, analysis of their summer movement patterns is crucial to understand its impact on the human harvest later during autumn. In this study both reproducing (n = 45) and non-reproducing wolves (n = 12) reduced their movement range during summer to 66% and 67% of their annual movement range, respectively. Reproducing wolves increased their movement range from early to late summer while non reproducing wolves did not.
Majstorkning :
The corn plant came to Europe with Christopher Columbus in the 14th century and have
ever since bin cropped here, but corn haven?t bin very common in Scandinavia until
recently. The mainly use for this crop silage but even corn for grain is cropped in
Europe. Corn for grain is a common part of feed in beef and chicken farming. In Sweden
corn for grain is pretty rare but almost 1000 hectares are used for this crop, Lantmännen
Sverige is the biggest buyer of corn at the moment.
Nitrogen flow in Scania : substance flow analysis on a regional level
In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog.
The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.
Attitudes towards hedging by diversified and non-diversified farmers : a comparative qualitative study
Deregulation on the market for agricultural products leads to a more globalised market with increasing price fluctuations. This, in turn, places the farmer in positions influenced by new risks but also improved opportunities. The farmers are faced by uncertainty in terms of financial outcome. To be able to utilise these new market conditions it becomes increasingly important for farmers to continuously follow the price trend, and to develop strategies how to manage the risks exposed by a volatile market.
Farmers with different conditions perceive risk in different ways. Hence, their risk management behaviour will vary.
Pallaskattens (Otocolobus manul) beteende i två djurparker - påverkan av hägndesign och miljö
The Pallas cat is a small cat living in central Asia. The cat is approximately the size of a domestic cat but the Pallas cat is more stocky build and has a much thicker fur that enables the cat to live in a climate with temperatures plummeting to -50°C. The thick fur is one of the reasons this cat has been a popular game for hunters in the past. Nowadays there are other threats to the Pallas cat. One of the major threats today is the reduction of food sources.
Inverkan av SPC på induktion av protein AF och produktionsresultat hos slaktkyckling
This study was a degree in Master of Science in agriculture with specialization in animal science for the Department of animal nutrition and management at SLU. The subject was created by AS-Faktor, a small company for science and development within the company Lantmännen AB. It was a test of the effect of SPC (Special Processed Cereals) on induction of the endogenous protein AF (an antisecretory factor) in plasma and intestinal lumen in broilers. Previous results have shown positive effects on different intestinal diseases in pigs, horses, dogs as well as in humans. Beside the induction we also studied the effects on results in a conventional slaughter chicken production, including the ability of SPC to compete with or be affected by the coccidiostat, Salinomax.When diarrhoea occurs, it's because there is an imbalance between the secretion and the absorption and it can be caused by for example toxins.
Aktivitet, läggnings- och resningsbeteenden, tillväxt samt renlighet hos kvigor i liggbås respektive djupströbäddsbox :
The aim of this study was to compare activity, lying down and getting up behaviour, weight gain and cleanliness in heifers in cubicles versus on deep-litter.
The study was conducted from autumn of 2005 until autumn of 2006 in a commercial organic dairy herd with 340 cows. In 2005 the farm rebuilt half of the young stock accommodation from deep-litter pens to cubicles. The experiment used 150 heifers of the breeds Swedish Red, Swedish Holstein and crossbreeds between these, all born on the farm. The animals were divided into three blocks based on breed and within each block they were sorted after increasing age. The youngest heifer in each block was randomly allocated to one of two groups, cubicle or deep-litter pen.
