Jämförelse mellan viltbehandlade och obehandlade granplantor : Med inriktning på höjdtillväxt och betesfrekvens

The report is a comparative study between spruce plantations where 4 plants are treated with deer repellents and 4 plantations are untreated. The study aims to provide a base for the Forest Society's future decisions regarding the use of wildlife-repellents.  The report indicates that wildlife-repellents work reasonably well for its purpose, the treated stocks were virtually untouched during the planting year and next year while the untreated stocks have been heavily grazed during these years.  Growth difference between grazed plants and ungrazed plants found to be virtually non-existent (0, 01 m) of the treated stocks and 0, 07 m in the untreated plants. Because of the growth differences are so small between grazed and no grazed plants, it seems like the treatment of deer-repellent are unnecessary. Unless you know in particularly that the area has a specific problem whit severe deer-grazing..

Automatic registration of dairy cows grazing behaviour on pasture

Information regarding cows grazing behaviour and time spent grazing can be of great interest to dairy farmers, since this information can indicate how well suited the pasture is to the cows. Feed intake at pasture is however challenging to measure. Automated systems for monitoring the behaviour of cows within dairy production have become increasingly important and relatively common. The aim of this study was to validate an activity measuring device (HOBO® G Logger Pendant Data Logger, USA), a triaxial accelerometer that registers the cow?s head positions during grazing, in order to see if cows? grazing behaviour on pasture could be distinguished from their non grazing behaviour.

Grazemore DSS för att optimera utnyttjandet av bete i mjölkproduktionen :

The aim of the study was to investigate if the Grazemore Decision Support System (DSS) is able to provide a grazing management strategy that gives a high utilisation of grazed grass in milk production in the north of Scandinavia. To do this, a grazing experiment was planed and performed during the summer 2005. Simulations in the DSS were run to get a suggestion of how the cows should graze, grazing calendar 1. Deviations and updates during the season resulted in the simulated grazing calendar 2. During the experiment, the actual milk yield was recorded twice weekly. The difference between actual and predicted milk yield by Grazemore DSS was analysed statistically with regression analysis and the mean square prediction error (MSPE) was estimated.

Kombinationsbruk, talltimmer och vilt?

When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.

Nedskrivningsprövning av goodwill : En studie av diskonteringsräntor på Nasdaq OMX Stockholm

Goodwill accounting has for a long time been, and with the implementation of IFRS in 2005, has become an even bigger issue. Critics mean that reporting of goodwill impairments is subject to discretion that can be used by the managers. We have applied a study made by Carlin and Finch (2009) on Nasdaq OMX Stockholm during 2006-2012. Our study contains 50 of the 255 public companies at 2012-12-31. The purpose of the study is to investigate if companies use an opportunistic discount rate when testing for impairment in goodwill and if the relation between goodwill and net profit before taxes, goodwill intensity, is an incentive for opportunism.

Betesskador på lärkplantor

The purpose of this study was to show how the Hybrid Larch (Larix eurolepis x) are used by large herbivores in terms of grazing and fraying. More specifically I studied how impact on the seedlings was affected by forest stand area, tree height and stem density (stems/ha).The survey was done in Jönköpings county in southern Sweden. About 50 % of all stems that are measured are damaged by grazing and 5,8 % was damaged from fraying. The conclusion of the study is that the biggest influencing factor is the height of the seedlings. The size of the stands and number off seedlings per hectare have almost no impact on the injuries on the seedlings. Fraying are common on trees smaller than 3 meters, and doesn?t occur on trees above that height.

The effects of Gotland pony grazing on forest composition and structure in Lojsta hed, south eastern Sweden

Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.

Grazing behavior of Ankole and Boran cattle in an improved herding production system

To be able to provide the growing human population with food, the productivity of the animals as well as land use needs to be improved and intensified. Hence, understanding the behavior of animals is crucial both for animal welfare and productivity as well as the management of the cattle. There are many factors affecting the grazing behavior of cattle in tropical conditions, such as human-animal interactions, herd management, breed, season and temperature. The purpose of this study was to investigate the grazing behavior of two tropical cattle breeds, Ankole and Boran cattle. Kenyan Boran belongs to a zebu type of cattle and is preferred to many other breeds due to the higher productive and reproductive capacity and adaptability to tropical conditions.

Effects of koccidiae- and nematode infections in first-year grazing calves :

Twenty-four calves, which had not grazed previously, were divided into four groups. They were subsequently inoculated orally with either E. alabamensis oocysts, O.ostertagi/C. oncophora larvae, or both. One group remained uninfected and was used as a control.

Rental rates and land prices have gone through substantial changes the last two decades. The prices have both gone up and down since 1990 but from 1995 to 2008 land prices increased with 272 percent and rental rates with 61 percent. What factors that have the largest impact on rental rates and land prices are hard to determine but factors that may affect the price are the desire to live in the countryside and the expected profitability in agriculture. Prices of products and inputs are factors that affect the profitability in agriculture, but the profitability is also affected by agricultural policies. The economic for Swedish agriculture have changed several times over the last 20 years as a result of changing agricultural policies.The agricultural policies largely affect farmers behavior and decisions.

Klassning av renbete med hjälp av ståndortsboniteringens vegetationstypsindelning :

During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.

Individuell lönesättning för enhetschefer

 Abstract The purpose with this study is to study the individual setting of salary rates among branch heads. We have chosen to look deeper into which criteria that are the base for the branch heads? individual setting of wage rates within geriatric care and the care of disabled people. One other aspect we have looked into is how the setting of salary rates appears from a gender perspective. The empirical material in our thesis consists of both qualitative and quantitative methods in the shape of a questionnaire study and three open interviews.

Variation in piglet mortality between and within satellites in a sow pool

The piglet mortality rates have become a major issue in today?s pig production. While other production traits such as number of born piglets or produced piglets per sow have been improved, the mortality rate has escalated. High mortality rates before weaning does not only affect the economy but must also be looked at as both an animal welfare problem and an ethical issue. The background to this problem has been addressed many times, and its salvation has also been addressed by breeding.
