Genetic variation in dairy cattle claw health traits recorded by claw trimmers

Claw health has been recorded by claw trimmers at trimming in Sweden since 1996, but data was then captured at each AI association. From 2003 data was captured by central scanning and entered directly to the national cow data base at the Swedish Dairy Association (SDA). This reporting was introduced because SDA wanted to be able to use these records to improve dairy cow Claw health by breeding. It is desirable with cows that have healthy claws, because poor Claw health can contribute to impaired production and fertility. The Claw health report begins with some information about herd, claw trimmer, date et cetera and continues with the part where the Claw health is recorded. Here the ID of each cow is filled in and on the same row the conditions for dermatitis, heel horn erosion, sole haemorrhage and sole ulcer are recorded as no lesion (blank), slight lesion (/) or severe lesion (X).

Genotype by environment interactions of claw health in Swedish dairy cattle in tie stalls and loose-housing

Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. This raises the question if there are genotype by environment (GxE) interactions for claw diseases in different housing systems. To investigate this claw trimming records for Swedish Red dairy cattle (SR) and Swedish Holstein cows (SH) were retrieved from the Swedish Dairy Association.

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.

Klövhälsa hos får : ur ett nationellt och internationellt perspektiv

Lameness causes suffering and poor performance in sheep, as in other species. The cause of lameness often originates in problems of the claws. Many claw diseases of sheep are described in British and Australian research, but this field has previously not been of special concern in Sweden. This graduate thesis contains the first Claw health survey made on Swedish sheep. The chief objective was to give an overview of sheep claw diseases and to assess Claw health in adult sheep.

Klövhälsa registrerad vid rutinmässig verkning i lösdrift eller uppbundna system med ekologisk eller konventionell mjölkproduktion :

KRAV-certified organic dairy herds generally have a lower milk yield than conventional dairy herds. A high-level of milk yield requires a feeding regime with high amounts of concentrates, a factor known to contribute to the development of claw lesions (Bergsten, C. 2003). The aim of this study was to compare Claw health between organic and conventional dairy herds in free and tie stall systems. The number of herds from different domestic animal health associations was chosen in proportion to the association´s total portion of Swedish dairy producing herds of each type, respectively.

Effects of rubber alley flooring on cow locomotion and welfare

This study investigated the effects of rubber alley flooring on cow locomotion, claw and leg health, production, cleanliness, grooming behaviour and cow exclusion rate in a free stall herd. The study was conducted in a new dairy house with a rotary milking system, with a matched group of cows on traditional scraped concrete alleys used for comparison. All claws were trimmed and lesions recorded at the beginning and end of the 4-month study. Locomotion, claw and leg health, behaviour and hygiene were observed and scored at regular intervals during the study. The results showed that cows on rubber alley floors displayed significantly (p.

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.

The effect of hoof trimming on dairy cows´ behaviour, locomotion and production

The Swedish dairy production today consists of big farms and different housing systems are in use. These systems put demands on the cows? ability to cope with the environment and one challenge is the Claw health in the herds. Some claw lesions that are frequently observed are foot rot, hemorrhages, digital dermatitis and sole ulcers, which can be caused by, for example, the claws? environment and the flooring type used.

Klövform och klövsjukdomar hos intensivt uppfödda köttrastjurar :

The top selection of Swedish beef bulls are evaluated yearly by Svensk Köttrasprövning AB at Gismestad. The bulls are selected from six different breeds; Angus, Blonde d´Aquitaine, Charolais, Hereford, Limousin and Simmental, and are kept on straw bedding apart from a concrete alley in front of the feeding area during the six months of evaluation period. The bulls are evaluated according to their fertility scores, growth, exterior and temperament and the exterior, body posture and claw conformation reflect important qualities for their longevity. In spite of good values for fertility, it has been noticed in the last years that the fertility results and longevity have been unsatisfactory and claw and/or bone disorders have been suspected as a contributory cause. Persson et al. (2007) studied breeding bulls from Gismestad and other places, which had been slaughtered due to poor fertility (no pregnancies in the herd during their last year in service).

Klosjukdomar hos hund : en litteraturstudie och en fallstudie i den Svenska Riesenschnauzerpopulationen

Various problems with nail disorders have been noticed in the Swedish population of Giant Schnauzer, but the frequencies of these problems are unknown. This could be due to the fact that bad nail quality has several differential diagnoses and lack of diagnostic criteria and diagnostic codes for nail disorders. The main purpose of this study is to review different types of claw defects and diseases of the nail bed in dogs, and to classify and evaluate the proportions in the Swedish Giant Schnauzer population. The nail is a specialized part of the skin. The quick will strengthen and protect the third phalang against the surrounding.

Införande av mjuka golv för mjölkkor : en fallstudie

Soft rubber flooring have gained in popularity over the last years. Rubber flooring al-lows cow to move more freely without slipping and improves claw and leg health. The purpose of this study was to investigate the influence of a stepwise introduktion of soft flooring on cow`s placement in cow houses with robotic milking. A case study was carried out in a herd in northern Sweden with 41 cows. Observations were made every 15 minutes between 09.00 and 16.00 concering cow placement in cu-bicles, in cubicle alley, in feeding alley and in feeding alley with the head through feed-ing gate. One observation period was carried out per flooring alternativ: 1) all concrete slatted floor, 2) rubber slatted floor in feeding alley and concrete slatted floor in cubicle alley and 3) rubber slatted floors in feeding alley and solid rubber floors in cubicle alley. The study showed that 6 %-units fewer cows lay in the cubicles when the feeding alley surface was slatted rubber.

Herbs for horses

The aim of this study was to find out how many and which of the herbs used for horses that have been scientifically studied with results to justify the use. In order to find out which herbs that are commonly used by horse-owners a phone interview was performed where six companies selling herbs for horses was contacted and asked to provide information on the most sold herbs for horses in Sweden. Devil's claw (Harpagophytum procumbens), chamomile (Matricaria recutita), dandelion (Taraxacum officinalis), nettle (Urtica dioica) and monk's pepper (Vitex agnus-castus) where the most sold herbs, followed by marshmallow (Althaea officinalis), burdock (Arctium lappa), marigold (Calendula officinalis), purple coneflower (Echinacea angustifolia/purpurea), cleavers (Galium aparine), licorice (Glycyrrhiza glabra), rose hip (Rosa canina), thyme (Thymus vulgaris) and vervain (Verbena officinalis), in no particular order. Of the most used herbs, research with focus on the use for horses was found for purple coneflower, licorice, devil's claw, monk's pepper, rose hip, thyme, and vervain. These studies did not cover the whole range of traditional use for the mentioned herbs, and more studies are needed to be able to claim that these herbs have, or have not, scientific support for use in equine management..

Möjligheter till utveckling av en hälsofrämjande skola

School can be an effective environment for achieving a more equal health among children and adolescents, since many individuals can be reached by the health promoting work in the school. In the year of 2000 a project in Skåne was started for the development of health promoting schools. The health promoting projects however, have shown to be of short duration. So, as an alternative, the integration of the health in school ought to be tried. The aim of this study is to give examples how health promoting schools can strengthen their profile.

Vårdvalet - Val för alla? : Granskning av fördelningen av vårdcentraler före och efter vårdvalsreformen

This master thesis is an analysis of how the amount of health centers per inhabitant has changed since the Swedish government implemented a new health care reform in 2010. The reform implies a free choice of health centers in the Swedish regions and opens up the market for private firms. The purpose of the thesis is to study the effects of the different financing systems toward the health centers in the regions. The models are based on theories of the need of health care. Two of the independent variables which are studied are income and age.
