    Abstract : The aim of the present thesis was to investigate hormonal and physiological effects in mothers during a breastfeeding session and in dogs and their owners in response to short-term interaction. In study one, sixty-six mothers receiving either exogenous oxytocin infusion and/or epidural analgesia (EDA) during labor or intramuscular oxytocin injection post partum were studied. READ MORE

  5. 8. Health and herd health planning in organic dairy herds

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

    Abstract : The status in European organic dairy production does not in all aspects, meet organic principles with regards to the aims of good animal welfare and health, and consumers’ expectations, and therefore needs to be improved. The aims of this thesis were to; assess the status of animal health in organic dairy herds; assess the structural characteristics, and their relation to implementation, of animal health plans; and to investigate a structured participatory and farm-centric approach.

  6. 9. Progesterone profiles, oestrus expression and pregnancy in dairy cows

    Author : Sofia Nyman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : The cow’s ability to reproduce is essential for milk production. Traditionally genetic evaluations for fertility have been based on measures on insemination- and calving dates, which in general are highly influenced by on-farm decisions. Unfortunately, the low heritability of classical fertility traits makes the genetic improvement slow. READ MORE

  7. 10. Dairy cattle mating plans at herd level using genomic information

    Author : Christian Bengtsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Genotyping of dairy cattle can benefit farmers by increasing the accuracy of breeding values and improving mating plans at herd level. Validation studies on breeding values in this thesis revealed that for the vast majority of traits analysed in Holstein, Jersey and Nordic Red Dairy Cattle, genomically enhanced breeding values for virgin heifers were able to predict cow performance significantly more accurately than parent average breeding values.
