  1. 1. On-farm cow mortality in Swedish dairy herds

    Author : Karin Alvåsen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : A high rate of on-farm cow mortality (i.e. unassisted death and euthanasia) is both a financial concern and an important animal welfare issue. The overall aim of this thesis was to evaluate the development of mortality in Swedish dairy herds and to identify characteristics associated with on-farm mortality at cow and herd levels. READ MORE

  2. 2. Factors associated with spontaneous oxidized flavour in cow´s milk

    Author : Jessica Juhlin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Spontaneous oxidized flavour (SOF) is an off-flavour in milk that has received attention in only a few countries, primarily due to lack of monitoring. The poly unsaturated fatty acids in milk are considered to make it more prone to oxidize, with effects like shorter shelf life of dairy products and a reduction in consumer acceptance of milk.

  3. 3. Feed efficiency in dairy cows: individual cow variability in component traits

    Author : Abdulai Guinguina; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Feed efficiency (FE) varies between cows, and this variation is linked to the variation in energy metabolism variables. Respiration chambers are needed for measuring energy metabolism variables while individual cow dry matter intake (DMI) records are necessary for measuring FE, but these are difficult to obtain due to cost and logistic constraints.

  4. 4. Methane production in dairy cows : individual cow variability in methane production

    Author : Edward Hernando Cabezas Garcia; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Enteric methane (CH4) emissions vary between individual cows, and this variation is attributed to both animal and dietary factors. In addition, measurement technique of in vivo CH4 emissions from individual animals still represents a major challenge for successful emissions mitigation strategies. READ MORE
