  1. 1. Sleep in dairy cows

    Author : Emma Ternman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Little is known about rest and sleep in dairy cows, but it has been shown in other species that the total amount of sleep, duration of sleep bouts and distribution of sleep over 24 hours differ depending on health status, age, pregnancy and lactation. Sleep recordings conducted on cows with surgically implanted electrodes have shown that they sleep four hours per 24-hour period. READ MORE

  2. 2. Non-coagulating milk from Swedish Red Dairy Cattle : Influence of milk composition, physical properties and genetic parameters

    Author : Kajsa Nilsson; Institutionen för livsmedelsteknik; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Non-coagulating milk; genetic parameter; milk composistion; heritability; protein profile; hydrolysation;

    Abstract : Non-coagulating (NC) milk is unwanted in cheese production, as it lowers cheese yield and prolongs processing time. Less yield will lead to economic losses at the dairies. Even if NC milk has been found in several breeds, studies suggest that Swedish Red Dairy cattle (RDC) has a higher frequency of NC milk than most other breeds. READ MORE

  3. 3. Environmental Improvments of the Post-Farm Dairy Chain: Production Management by Systems Analysis Methods

    Author : Johanna Berlin; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environment; cheese; dairy products; life cycle assessment; dairy; production scheduling; environmental systems analysis; actor analysis; yoghurt; LCA;

    Abstract : The production of dairy products is becoming more centralised at the same time as the number of different products is steadily increasing. In this thesis. the environmental impact of such ongoing development trends in the post-farm dairy chain was evaluated and improvements were suggested. READ MORE

  4. 4. Assessing phosphorus overfeeding in dairy cows

    Author : Maria Nordqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Faecal total phosphorus (TP) from dairy cows consists of a largely insoluble fraction and a soluble P fraction (SP), which mainly represents excess P. The soluble fraction increases proportionately with increased P feeding as excess P is mainly excreted with the faeces in soluble form. READ MORE

  5. 5. Predicting methane production in dairy cows

    Author : Mohammad Ramin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Methane is a potent greenhouse gas, to which enteric fermentation from ruminants contributes significantly. Reliable and accurate predictions of methane (CH₄) production from dairy cows would be of interest to develop mitigation strategies and for national inventories. READ MORE
