  2. 1. Organic dairy production : herd characteristics and genotype by environment interactions

    Author : Therese Ahlman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The aim of this thesis was to gain further knowledge about the performance of cows in organic dairy production and their ability to adapt to the organic production environment. Milk production traits, fertility traits, somatic cell count (SCC) and longevity traits were analysed in organic and conventional herds and the reasons for culling in the two systems were investigated.

  4. 2. 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

  5. 3. Domestic protein feeds in dairy production : potential of rapeseed feeds and red clover

    Author : Helena Gidlund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The purpose of the four studies that form the basis for this thesis was to extend the knowledge about how to utilize the domestic protein feeds in Swedish dairy production. To optimize the use of nitrogen (N) from both concentrates and forages into milk product, and thereby improving the profitability and the resilience of the domestic dairy farms. READ MORE

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

    Author : Kajsa Nilsson; Avdelningen för livsmedel och läkemedel; []
    Keywords : 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

  7. 5. Gas emissions from dairy cow and fattening pig buildings : effects of animal parameters, climatic factors and manure management on methane and ammonia missions

    Author : Ngwa Martin Ngwabie; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The objective of this research is to contribute to the knowledge concerning the abatement of gas emissions from livestock production. Investigations regarding the choice of sampling locations for gas concentration measurements, quantification of gas emissions and the factors that affect gas emissions were conducted. READ MORE
