Diurnal behaviour of cattle, sheep and goats on semi-arid pastures in Kenya
Studien genomfördes i Shompole i södra Kenya. I det här området är invånarna herdar som förlitar sig på kor, får och getter som sin enda inkomstkälla. De föder upp boskap under extensiva förhållanden, med naturligt bete som huvudsaklig födokälla för sina djur. Sex besättningar av den typen ingick i studien som genomfördes från mitten av december 2009 till mitten av februari 2010, vilket gav totalt 65 observations-dagar.
Syftet med studien var att samla in födo- och förflyttningsbeteende hos nötkreatur, får och getter på bete.
Association between animal-based measures and register-based welfare indicators in dairy cows : a study of the advisory service "Ask the Cow" and the web report "Animal Welfare Signals"
Animal welfare can be measured in several different ways; for example by using animal-based measurements. It has been shown that register data from the Swedish Official Milk Recording Scheme can be helpful when identifying herds at risk of having poor animal welfare, which led to a development of the advisory service of ?Ask the Cow? and the web report ?Animal Welfare Signals?. The aim of this project was to find out if register data from ?Animal Welfare Signals? can be used as a screening tool for detecting herds at risk of having poor animal welfare and in need of an ?Ask the Cow?.
Norrländsk känsla för Japan
Sweden signed, in 1992, the Convention on Biological Diversity (CBD) and has thus assumed responsibility for the indigenous biodiversity. That also means that Sweden has a conservation responsibility for the Swedish Friesian (SLB) (SJV, 2007a). In a survey conducted by the Board of Agriculture (SJV) in 1996, it appeared that there were around 780 cows and heifers of the SLB breed (SJV, 1997). SJV did in 2006 a plan for the development of livestock genet-ic resources and the number of cows of SLB was estimated at approximately 200. This meant that the SLB was in need of being conserved and SJV assumed it would be categorized as threatened.The primary objective of conservation of a breed is to reduce the loss of the original genetic variation (Lacy et al., 1995).
Levande vikt vid olika åldrar och sambandet med bröstomfång och mankhöjd hos SRB och SLB :
Live-weight at different ages for Swedish Holsteins (SLB) and for the Swedish Red and White Breed (SRB), and the correlation to heart girth and height at withers.
The aim of this investigation was to study the live-weight changes and mature weight for the Swedish Red and White Breed (SRB) and for Swedish Holsteins (SLB), and to estimate the correlations between body weight and body measurements such as heart girth and height at withers, respectively. The material used was from one of the experimental dairy herds (Jälla) of the Swedish University of Agricultural Science. It included recordings on 293 dairy cows with information from 7142 weight occasions and recordings on 275 dairy cows with information of 557 heart girth measurements and 560 measurements of height at withers. The registrations were done during 1993-2002.
There was a large variation in live weight between cows in different ages and lactation stages.
Sustainability reporting within the food industry : a case study of regional differences in the plant-based non-dairy industry
Sustainability Reporting has emerged and transformed over the past decades as a voluntary practice by companies across industries that desire to show proof of good conduct and environmental; social; and economic responsibility. As industrial food production is one of the largest contributors to contemporary environmental problems, it might be expected that reporting within the industry would be both well established and well understood.
Unfortunately, it is neither. In light of the food industry?s considerable environmental impact and the growing popularity of plant-based food as a more sustainable alternative to dairy products, this paper assesses and briefly discusses the Sustainability Reporting of two companies in the plant-based food and beverage industry. The research was designed to compare the practices of Europe-based Alpro and US-based SoDelicious, and this study has two major purposes: to describe the reporting of the case companies and to subsequently
compare their practices to the other as well as to global reporting standards.
The empirical study in this paper was conducted through content analysis.
RTLS - real time location systems : an inventory study for agriculture applications and requirements
The trend towards increasingly large farming units raises questions regarding how to better monitor production. Larger units make the impact from possible errors more severe, which increases the pressure on management supervision. To cope with management issues, prevent errors and handle increased demands on traceability and documentation, the Real Time Location Systems (RTLS) concept is making its way into various parts of agriculture.
In sectors outside agriculture, RTLS are already being used successfully to track and locate items through nodes at different levels of accuracy, such as room level or the relative or absolute position. Empirical data can be received in real time from the nodes.
Djurförbud : en granskning av beslut enligt 29 § djurskyddslagen under 2006-2008
The purpose of this candidate thesis is to obtain an overall picture of how many prohibitions against owning or taking care of animals that were announced in Sweden in the years 2006-2008 and on what basis these judicial decisions were taken. What is the situation for the person behind the judicial decisions? Is there a so-called risk category where preventive actions to solve the problem can be taken at an earlier stage?The first Swedish animal welfare legislation came into force in 1944. Previously there was a law of 1857 that only prohibited the maltreatment of farm animals. In 1988 the existing animal welfare law was revised into an in principle new law (1988:534).As early as in the Royal Majesty?s government bill (1944:43) to the 1944 animal welfare legislation, there was a proposal that issued prohibition for those having been convicted of aggravated cruelty to animals.
Effekt av biotintillförsel på klövhälsan hos mjölkkor i lösdrift : ett kontrollerat fältförsök på tre gårdar
The Effects of dietary biotin supplementation on hoof health in Swedish dairy cows - a controlled cohort field study.
The aim of the present degree project was to investigate the effects of biotin supplementation on hoof health in dairy cows. The experiment was performed as a controlled cohort study in three commercial farms in western Sweden from January 2002 to October 2002. The cows were all housed in cubicle systems with transponder concentrate feeding systems. Within each farm the cows were allocated to either biotin or control treatment. The biotin groups received 20 mg of biotin per cow and day, starting 14 days before expected calving.
Mjölkningsfrekvensens påverkan på mjölkproteinets sammansättning och kvalitet :
In modern dairy production the milking frequency is increased in some herds due to introducing of automatic milking systems or the farmers decision to milk high producing dairy cows more than two times a day. With more frequent milkings the milk yield increases while the content of fat and protein decreases. However, how the composition of protein is influenced is not fully evaluated. The purpose of this study was therefore to see if a higher milking frequency had any impact on the milk production and especially on the protein composition.
This study was conducted as a half udder experiment.
Utvärdering av en snabbtest för diagnostisering av hypokalcemi hos nötkreatur :
Clinical signs of hypocalcaemia in dairy cows are easily recognized, and a rapid response to treatment generally confirms the diagnosis in the field. However, clinical signs of other disorders in cows, such as toxemia, calving paralysis, or muscoskeletal injury, may mimic those associated with hypocalcaemia. Therefore, making a diagnosis of hypocalcaemia on the basis of clinical signs alone may be difficult. In ambulatory veterinary practices, cow-side tests are useful to make the diagnosis and prognosis easier.
Kruuse?s Kalcium Test is a cow-side test based on the principle that calcium ions are necessary for coagulation of blood, and that chelation with EDTA prevent coagulation.
Lövängen i nordöstra Skåne :
The purpose of this paper is to study how the wooded hay meadow of the forest district of northeastern Scania is preserved today, and what local history it has, to thereby achieve a better understanding of the dynamics of the landscape and the complex of problems involved in keeping a historical element of the cultural landscape alive. To accomplish this, literature concerning the subject has been studied, experts have been consulted and an example, the old farm Sporrakulla in Östra Göinge municipality, has been studied. The paper states that the wooded hay meadow constitutes an important part of the history of northeastern Scania, where it provided leaf fodder and hay for the farmers keeping cattle. Today, however, only a few wooded hay meadows remain. One of these is the studied example at Sporrakulla, where juridical protection like Natura 2000 and financial support of maintenance like miljöersättningar make sure that the wooded hay meadow will remain.
Bristande mjölknedsläppning hos förstakalvare : en enkätstudie
Milk ejection in dairy cows can be inhibited if oxytocin is not released from the pituitary gland. The problem with inhibition of the milk let down is not new, but has recently regained interest. It is observed during different types of emotional stress, for example when cows are moved to an unfamiliar environment, during oestrus, changing from suckling to machine milking or when being milked for the first time.
The aim of the study was to examine the extent of cows with disturbed milk ejection in Sweden. A survey was sent out to 1000 dairy farmers in order to collect data about herd size, housing systems and routines at calving and milking.
Inhyrning av maskintjänster : ett alternativ till att använda egna maskiner vid vallskörd?
The economic conditions for Swedish dairy farmers are constantly changing. The numbers of
producers are declining and the economic conditions for dairy production are weakening
debilitating. To improve the economic situation for a farm a hired contractor is a possible solution since previous studies show that machinery cooperation may be beneficial for the farmers.
The aim of this study is to examine the possibility for farmers to cut costs by hiring a
contractor for harvesting silage. A comparison between using own machinery and hire a
contractor is the starting point of this study. Another aim is to discuss the farmer?s decision process when achieving today?s situation and to determinate what factors affect their decisions.
The study is based on cases selected from four farms that today have chosen not to or only to some extent, hire a contractor for harvesting silage.
Magnesium chloride in dry cow silage to prevent hypocalcaemia
Milk fever, or parturient paresis, is the second most common disease in Swedish dairy cows. The disorder is associated with the onset of lactation when some cows are unable to meet the metabolic demands of calcium to support milk production and therefore develop a state of hypocalcaemia. Clinical hypocalcaemia (milk fever) may lead to coma and death in severe cases but subclinical hypocalcaemia has also been shown to have negative effects on e.g. feed intake and production and to increase the susceptibility of the cow to develop secondary diseases. The nutritional strategy applied precalving is of great importance in preventing milk fever and e.g.
Val av liggplats och väderskydd hos dikor vid utedrift vintertid
If you keep cattle in a herd outside all year round on big varying grounds, their possibilityto perform their natural behaviour increases. This way of keeping cattle requires that youprovide them with their other needs, like shelter and a dry and clean resting place.According to the animal welfare authority´s regulations on livestock farming, only animalsthat are suited to stay outside during the cold season are allowed to be kept outside. Theyshould also have access to a shelter or another building that gives them protection from theweather and wind and provides a dry and clean resting place.Research has shown that as long as cattle do not get exposed to precipitation and wind theywill manage low temperature well. Some of the things that will affect how well the animalshandle different climates are the isolation ability of the fur, the animals´ body size and thefeed intake. A dry lying place that is both insulating and moisture absorbent is also of greatimportance.
