Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

Botanically diverse pastures are commonly used in New Zealand to reduce the ruminant environmental impact by reducing the methane production from the rumen digestion. In order to evaluate the effects diverse pasture species have on the milk fatty acid profile seventy-two lactating Friesian-Jersey crossbred dairy cows were used in a randomised block design with two replicates of six treatments. Six different pasture mixtures were fed at a daily allowance of approximately 15 kg DM/cow/day. The mixtures were categorised as either a simple or a diverse pasture. The simple mixtures all contained white clover with the addition of either a standard diploid perennial ryegrass (RG), a diploid high sugar ryegrass (HS) or tall fescue (TF).

The decrease in the number of dairy farms in Sweden has been ongoing for a longer period of time. But the fact is that this has previously not had any big effects on total amount of milk produced in Sweden. The main reason is that the remaining dairy farms get larger. However, during the past year, there has been a decrease in the total amount of produced milk, because the decrease is faster than the increase within the farms that are left. During the same period of time the supply of milk on the global market also has decreased. In spite of the fact that the global supply have decreased and the fact that the milk price increases, there are dairy farmers in Sweden who chose to exit the market.

Endast en procent av alla bröstcancerdrabbade per år är män. Det är ett område som är eftersatt i forskningen och dåligt uppmärksammat av både vården och samhället. Syftet med studien var att undersöka mäns upplevelser av att drabbas av bröstcancer. Den metod som användes var i form av en litteraturstudie med kvalitativ ansats. Urvalet bestod av sju vetenskapliga artiklar som fokuserade på mäns upplevelser av att leva med bröstcancer som sedan granskades utifrån Polit och Becks (2010) kriterier.

Concentration of protein in bovine milk is one of the most significant milk quality parameters, to a large extent determining the price for milk to the producer. Mastitis is a common disease among dairy cows, negatively affecting not only milk yield but also milk protein composition. Milk from mastitic cows tends to have lower cheese yield, negatively affected processability properties and sensory quality, due to changed protein quality and composition. Poorer milk protein quality would have an economically negative impact on dairy industry. Only few studies have investigated the short term effects of mastitis on milk protein composition.

Breast cancer is the most common form of cancer which struck women around the world. When a human is exposed to threat or stress, e.g. breast cancer, different coping strategies are used in order to cope with the situation by the afflicted person. The aim of this literature study was to describe how women, who suffered from breast cancer, experienced coping with their situation. Scientific articles were found in the databases Medline (Pub Med) and Cinahl.

I ett internationellt perspektiv har Sverige hög amningsfrekvens, men under 2000-talet har amningsfrekvensen sjunkit och stora regionala skillnader ses. Kvinnorna rekommenderas att helamma sex månader. Mödravårdcentralen (MVC) informerar om bröstmjölkens hälsoeffekter som till exempel att bröstmjölken skyddar barn mot allergier. Forskning visar att överviktiga och feta kvinnor har kortare amningsduration, men få studier behandlar svenska förhållanden. Syfte: Syfte med fördjupningsarbetet är att studera samband mellan mammans BMI relaterat till amningsduration och mammans skattning av barnets hälsa de tre första levnadsåren.

Heat stress negatively influences the performance of dairy cattle such as lactation and reproduction. Heat stress can cause production losses as well as welfare problems. Years of research have shown that heat stress is a huge problem for dairy cattle in both the tropics and temperate zones but no such research have so far been done in northern European countries. It seems like shade is an important tool when improving pasture conditions and therefore deserves more attention. The aim with this study was to investigate whether there is a need of providing shade for grazing dairy cows during the summer in Sweden. Two groups of lactating Swedish Red dairy cows (n=15 per group) were kept on pasture.

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.

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

Background: The women who were called in for further examinations after a breast screening had all their examinations and test during one day. This organization has been conducted since 1993 in this clinic, but has not previously been evaluated. Aim: The aim of this study was to investigate the patients? experiences of the organization, in a radiologic breastcancer clinic, where all the examinations and the test-results were given at the same day. Method: An empirical quantitative study was performed.

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.

Cows affected by mastitis caused by Klebsiella (K.) pneumoniae often become seriously ill. In some cases herdproblems may occur. Contaminated bedding material is considered to be one of the most common risk factors for klebsiella mastitis. In a recently performed study in USA it was found, however, that more than 80 % of healthy, lactating dairy cows excreted K. pneumoniae in faeces.

The coproduct, dried distillers grains + solubles (DDGS) from ethanol production based on wheat contains much rumen degradable protein and fiber with low digestibility. To compliment this quality in an effective way a grass silage low in protein and much digestible fiber is needed. The aim of the study was to investigate the effects of adjusting the crude-protein concentration and fiber quality of the silage when feeding DDGS and of varying the inclusion level of DDGS, when feeding the adjusted grass silage, on intake, milk yield and composition, faecal traits and feed efficiency. Four different total mixed rations were compared. The normal grass-clover silage had a crude protein content of 17,8 % and an NDF content of 46,2 % of dry matter. The adapted grass silage had a crude protein content of 14,6 % and an NDF content of 52,9 % of dry matter. The diets were formulated to have similar nutritional content except for A + 4 which had a higher content of rumen degradable crude protein and a lower concentration of NDF.
