Babesios : en fallbeskrivning samt diskussion av fästingburna sjukdomar hos nöt i Sverige

Many farms in the counties in the south of Sweden have difficulties with diseases spread by ticks; mainly babesiosis and tick-borne fever (TBF) but there are indications that borreliosis ought to be included. All of the tick-borne diseases radically decrease farm profit if the herd is affected. The production of the vaccine used against babesiosis since the 1920´s, will be discontinued in the near future and in addition to economical reasons it is therefore important to learn more about the diseases above. During the summer and fall of 2002 and 2003, a farm in the island of Gotland was burdened with unusually many cases of bovine babesiosis. In total 43 animals fell ill and one died.

Berthåga kyrkogård

The aim with the literature study is to inform about the risks that exists in large dairy farms(with focus on mastitis and hoof health) and to inform about the milk industry in Sweden.Personal comments from two study visits (Nötcenter Viken and Vadsbo Mjölk AB) arelinked together with the literature and forms into a discussion regarding sustainableagriculture versus the milk cow's welfare.The profitability for Sweden's milk farmers have decreased because of the decreased milkprice and current inflation. This leads to an increase in herdsize in order to make a profit.The milk cow herds in Sweden becomes fewer year by year and the herdsize increases. Theincreased herdsize can cause a decrease in the time the farmer spends per animal. This canaffect early disease detection and prolong the animals suffering.Swedish Board of Agriculture published (2008) statistics showing that today's milk cow ismedicated primarily because of two reasons; mastitis or hoof problems. Mastitis is thereason to two thirds of all treatments that are carried out.

Animal welfare in Ethiopia: handling of cattle during transport and operations at Kera Abattoir, Addis Abeba

The main objective of this study was to evaluate animal welfare situation in Ethiopia during slaughter and to investigate chain activities between animal markets and Kera abattoir in Addis Abeba. In total, 442 animals were observed within 52 groups of cattle; both ox and calves with different breeds. The study was divided into four different sets of data collection; behavioural observations, recording of slaughter process, observation during transport and interview. During the behavioural observations, an ethogram was used with 46 behaviours observed, categorised into 5 different groups. The data was calculated using Excel and SAS. The results indicated that a significant correlation (p-value.

EU ger eko bland korna - från uppbundet till lösdrift :

ABSTRACT For hundreds of years there has been a tradition with tethered dairy cows in Sweden. The last decades the old fashioned way to hold cows have been questioned and the number of dairy cows in loose housing has been increasing. Last year (2004) 19 percent in total of all farms with milk production in Sweden had their cows in loose housing. Because of EU-legislation concerning all organic production no farms are allowed to build tie stalls any more and after 2010 all organic dairy cows are supposed to live in loose-housing systems. The aim of the thesis was mainly to find out the number of farms with tethered organic dairy cows and if they will continue after the year 2010. Furthermore the purpose was to study if there are any regional differences, how countries similar to Sweden interpret the EU-decision about tethered cows and differences in buildings between organic and conventional farms and the reasons to them.

Åkerböna i samodling med vårvete som helgrödesensilage till mjölkkor :

The aim of this undergraduate thesis was to formulate advices regarding the use of field beans, cultivated together with spring wheat, as whole-crop silage in feeding to dairy cows. In the thesis, optimal harvest time of the field bean/spring wheat crop, as well as the feeding value and the fermentation quality, was studied. On the research station at Röbäcksdalen in Umeå field bean/spring wheat (70 % respective 30 % of normal seed rate for the pure crop) and pea/oat (70/30) was grown in field experiments both 2002 and 2003. The following year, 2004, the pea/oat crop was excluded and instead field bean and spring wheat was cultivated in three different mixed ratios (field bean/spring wheat; 100:0, 70:30, 30:70). Every year the crops were harvested at four different development stages and the green forages were used in ensiling experiments.

Inverkan av den genetiska defekten Complex Vertebral Malformation på fruktsamheten hos SLB :

Complex Vertebral Malformation (CVM) is an autosomal recessive inherited defect in the Holstein breed. The defect has lead to structurally malformed calves and losses of pregnancies. To determine the effect of CVM on fertility in the Swedish Holstein Breed 375 Holstein bulls used in breeding by Svensk Avel and Skånesemin were assigned to this study. 228 bulls matched the criteria of birth year, 1995-1999, > 75 inseminations and a known CVM-status. Of the total 228 bulls 53 of them were CVM-carriers and 175 were non-carriers. The SAS-programme was used to determine the effects of CVM-status, the bull?s father and birth year on Non-return rates (NRR) for 28, 56 and 168 days.

Miljöpåverkan av Cu från mjölkkors klövbad

Klövsjukdomen digital dermatit hos kor ger upphov till smärta hos djuren samt störningar i produktionen. För att förebygga och behandla klövsjukdomen används olika preparat, däribland CuSO4-lösning.Syftet med studien är att undersöka om och i så fall i vilken omfattning spridande av kopparförorenad gödsel påverkar Cu-halten i jordbruksmark.Studien genomfördes med provtagning av två oberoende jordbruksmarker där ett av områdena gödslas med kopparförorenad gödsel. Resultaten visar att jordbruksmark där förbrukad CuSO4 spridits med stallgödseln ger upphov till en signifikant ökad Cu-halt i markens översta lager, 0-25 cm.  .

Kalvhyddans utformning : påverkan på kalvens hälsa och komfort

This paper aims to, through a literature review, examine how to best design and adapt calf huts to meet the calf's physiological requirements and reduce the infection pressure for enteric and respiratory diseases. It illuminates how the calf relates to different temperatures and climate, which temperature control mechanisms it uses and its ability to perform these regulations, as well as providing a summary of the past decades´ research on the calf huts housing system. These two theory chapters, along with a concluding discussion, provide a better understanding of how to, especially in temperate climates, design the most suitable calf hut, which cater to the calf's both thermal comfort and physical health. The literature suggests that the calf's own temperature control works well to counteract the temperature outside the desired range, and that one of the most important factors rather is ventilation of a calf hut, which reduces moisture and pathogens. The conclusion of this paper is mainly that there is not an obvious way to place and construct a calf hutch and that most design principles contribute to both positive and negative effects simultaneously.

Factors affecting the heifer´s age at pregnancy

Several factors affect the heifer´s growth and development, the newborn calf´s feeding of co-lostrum during its first hours of life is one important factor. The colostrum contains higher amount of immunoglobulins and insulin growth factors compared to matured milk. A high intake of immunoglobulins from colostrum results in a high blood concentration of immuno-globulins until the age of eight months. This leads to a lower incidence of diseases that can affect the growth and development negatively. Diarrhea is the most common disease in calves younger than 30 days.

Mineralämnen i fullfoder : studier på 20 mjölkkogårdar i Halland

In 2003 the recommended phosphorus allowance for dairy cows in Sweden was lowered approximately 10 %. For a cow at a production level of 35 kg ECM it decreased from 0,40 to 0,36 % of dry matter. To investigate if the decrease has been implemented at farm level, analysis of following minerals; P, Ca, Mg, K, Na, S, Se, Cu, Mn and Zn was performed on the TMR at 20 farms in Sweden in the summer of 2004. The purpose was to describe the actual allowance of different minerals as compared to the new recommendations. One hypothesis was that the decrease in recommended allowance of phosphorus would lead to the need of new mineral feeds on the market.

Communication of CSR activities : a case study in the dairy sector

Recent corporate challenges require effective communication in order to secure a company?s reputation. Companies as a result, need to be committed to a series of corporate social and environmental practices along with their financial commitments to their shareholders and investors. In fact, businesses are required to go above their ordinary operations and involve all potential stakeholders that can be affected by their strategies. Companies also need to communicate social, environmental and economic consequences of their activities along with their CSR commitments to their internal and external stakeholders in order to make a better corporate image and improve their market opportunities.

Can increased activity recorded with help of activity monitoring sensor indicate an upcoming calving?

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

Prevalence of subclinical mastitis in dairy farms in urban and peri-urban areas of Kampala, Uganda

En operation framkallar en icke önskvärd fysiologisk reaktion hos patienten som benämns som kroppens stressvar. Stressvaret innebär att sympatiska nervsystemet aktiveras och att endokrina ändringar erhålls, bland annat minskning i sekretionen av TSH och insulin samt ökning i sekretionen av ACTH, kortisol och ADH. En viktig uppgift för en veterinär är att välja premedicineringsläkemedel innan en operation. Premedicineringsläkemedel har som främsta uppgifter att motverka det perioperativa stressvaret hos djuret, minska smärta och förstärka anestesimedlens effekt. Syftet med det här arbetet är att beskriva vad som händer i kroppen vid ett perioperativt stressvar och hur svaret kan motverkas med hjälp av premedicineringsläkemedel. Premedicineringsläkemedel väljs och kombineras från klasserna sedativa, analgetika och antikolinergika. De vanligaste använda sederande läkemedlen på svenska veterinärkliniker är dopaminantagonisten acepromazin och alfa2-agonisten medetomidin.

Samband mellan hög incidens ämnesomsättningssjukdomar och klövhälsa hos svenska mjölkkobesättningar :

Metabolic diseases in dairy cows are considered to increase the risk for claw lesions, most of all laminitis, sole haemorrhages and sole ulcers, but also to increase the risk for environmental claw lesions. The aim of this study was to compare claw health in 27 Swedish dairy farms, 18 with high incidence of metabolic diseases and 9 with low incidence. Data on claw health status was retrieved from recordings at routine claw trimmings and analysed on herd level regarding the prevalence of: any lesion, interdigital dermatitis, heel-horn erosion, sole haemorrhages, sole ulcer, lameness, abnormal claw shape, and other diseases (abscess in the white line, limb disorders, double sole, laminitic groove, white line disease, interdigital phlegmon, interdigital hyperplasia, toe abscess and verucose dermatitis). Mean prevalence of any lesion for herds with low incidence of metabolic diseases was 48 % and in herds with high incidence 41 %, and there was no statistical difference between the two groups. Mean prevalence for interdigital dermatitis was 2,0 % and 6.4 % in the low and high incidence groups, respectively (p.
